8.4. Possible Compression Trouble Areas

Like any signal processing, compression can be misused, and improper

application may cause undesirable side effects in the audio signal. Some of

these problems include:

1. Noise. If the threshold for compression is set too low, and the output gain

is raised substantially to make up for the gain loss of compression, the

resulting output signal can be noisy. This is because the overall signal

must be raised significantly to produce the same audible level, and the

noise floor of your equipment will be amplified unnecessarily. This prob-

lem will be exaggerated if the input signal level to the compressor is very

low (which will already degrade the signal-to-noise ratio).

2. Breathing. In situations where the compression ratio is high, the thresh-

old is low, and the release time of the compressor is short, the noise floor

will modulate up and down as the audio signal rises above and falls

below the threshold.

3. Over-compression. Applying too much compression to a mix can some-

times result in such evened-out dynamics that the “life” of the music or

speech has been removed or curtailed. Dynamic variation may be a major

component of a performer’s message and command of the audience;

don’t remove dynamics, just control them. This may be particularly true for

percussive musical instruments such as drums.

8.5. Release & Knee Settings

Two other important compressor variables are

release time

and

knee

. Re-

lease time adjusts the speed with which compression stops and output gain

returns to unity with input gain, once the input signal falls below the compres-

sion threshold. Knee refers to the degree with which the full ratio of compres-

sion is imposed once the input level threshold is approached and exceeded.

A “hard knee” changes from no compression to maximum compression ex-

actly and immediately at the threshold crossing; a “soft knee” gradually im-

poses the full compression ratio as the input gain approaches and exceeds

the threshold. In Sabine products, the “softness” of a knee can vary from 1-40,

with the higher level representing the “softest” character. In such a setting,

slight compression will begin well below the compression threshold, increase

as the input gain crosses the threshold, and reach full compression well

above the nominal threshold.

Values for release time and knee are set at the factory: default release time is

250 mSec, and the default knee setting is a “soft” setting of 20. These defaults

can be temporarily changed or reprogrammed using the Sabine True MobilityTM

Remote Software (see Section 13 for details).

9. DE-ESSER

9.1. De-mystifying De-essers

Certain consonant sounds produced by the human voice contain more energy

than others, and have the potential to overload a microphone capsule. This

can produce a disproportionately harsh result when amplified through a sound

system, and/or recorded to analog or digital storage media. The most com-

mon and obvious of these sounds (in English and many languages) is the

“ssss” sound, associated with pronunciation of both “s” and soft “c” conso-

nants, also the consonants “t,” “f,” “x” and sometimes “d.” The technical term

for this particular vocal sound is “sibilance,” and the devices that control such

sounds are typically called “de-essers” (or sometimes sibilance controllers).

The frequency range of sibilance will vary depending on the singer/speaker,

the consonant involved, the orientation to the microphone, the microphone

itself, and the normal variations in human vocalization. Cardioid- pattern con-

denser microphones are especially susceptible to sibilance problems, but

the problem can also occur with other types and patterns of microphones. The

range of frequencies affected by sibilance starts above 2 KHz, and generally

tapers off above 10 KHz; in other words, sibilance is primarily a problem asso-

ciated with higher frequencies (though not the upper octave of human hear-

ing).

9.2. The Sabine De-esser

The Sabine De-esser is essentially a type of frequency-band compressor,

active in the 2-10 KHz range, and inactive below 2KHz and above 10 KHz.

Sabine’s algorithm works by dynamically comparing band-specific and asso-

ciated harmonic energy levels to the total signal energy. When spikes are

detected that correspond to sibilance, a shelving filter is imposed on the ap-

propriate frequency bands, and remains in place only for the duration of the

sibilance. High frequency energy levels that remain below the comparison

threshold do not trigger de-essing, and lows and highs outside the sibilance

range are also passed unprocessed and unaffected. This means the Sabine

De-esser is effective but transparent.

9.3. Using the De-esser

Using the Sabine De-esser is simplicity itself. Turning the knob labeled “DE-

ESS CUT” counterclockwise will increase the amount of sibilance reduction,

by increasing the maximum depth of the shelving filter. The maximum allow-

able cut is 24 dB.

10. PROGRAM SAVE & RECALL

Most wireless microphone systems provide control of one or two settings (RF

channel and maybe gain). With so little to remember, the ability to save and

recall system settings has not been necessary. With the Sabine SWM7000

series, however, you get a very sophisticated processor with a variety of adjust-

able parameters. The ability to save and recall your carefully programmed

setups can be a tremendous time-saver. Your SWM7000 allows you to store

and recall up to 10 different presets.

10.1. Saving a Preset

To save a program, press the SELECT button. The last preset used (num-

bered 01 - 10) will be shown in the LCD Display (see Fig. 10b). If you want to

replace an existing program, press SELECT until you reach that program’s

number. Then press the SAVE button. The function display will show “YES?”.

If you are ready to save, immediately press the SAVE button again, and your

settings will be saved to that program number. The message PRESET SAVED

will be shown for four seconds in the text display to confirm this action, as the

LCD Display continues to show the number (01-10) of the preset (see Fig.

10c). After four seconds, the LCD Display will revert to an indication of the RF

channel.

10.2. Loading a Preset

Loading a program is just as easy. Press SELECT until you locate the pro-

gram number you wish to load. Press LOAD. The function display will show

“LOAD YES?” (see Fig. 10d). Immediately press the LOAD button again and

your new program, including all the parameters, will be loaded for that chan-

nel. The message PRESET LOADED will appear in confirmation (see Fig.

10e).

10.3. Naming a Preset

Presets, channels and receivers can be named using the Sabine True Mobility

Remote Software. Refer to Section 13 for details.

10.4. Power Off Memory

The SWM7000 retains in memory all settings in effect at the time of being

powered off, and returns to those settings when powered on.

11. MULTIPLE SYSTEMS OPERATION

11.1. Overview

In many circumstances a single wireless microphone system is all that will be

in use at any one time. Larger applications (church, concert hall, theater

stage, conference room, etc), however, can often require a large array of wire-

less microphones, all demanding flawless uninterrupted simultaneous op-

eration.

Multiple system operation presents at least two important operational chal-

lenges: interference among transmission channels, and setup complexity.

The Sabine SWM7000 provides powerful solutions to both, particularly the

interference problems associated with two or more RF channels at work at the

same time, at the same location.

11.1.1. Multiple System Interference

Sabine’s SWM7000 addresses multiple system interference with two strat-

egies. First, greater available bandwidth in the 2.4-2.4835 GHz range means

more channels can occupy the band, i.e., the expanded range can be divided

into a greater number of separate transmission/reception bands. Second,

with Smart Spectrum transmission and reception, channels are more toler-

ant of interference. The net result is that the SWM7000 offers the potential for

many more simultaneous transmission channels than conventional UHF or

VHF systems.

While such performance benefits are one of the major advantages of the

SWM7000, more systems working at the same time leads to a greater po-

tential for complexity. Fortunately, the SWM7000 also offers tools to simplify

setup and operation.

11.1.2. Setup Complexity

Multiple wireless systems in a large installation are of course more compli-

cated than a single transmitter/receiver. More space is needed, and the

sheer quantity of transmitters and receivers that may be in use at a single

installation can prove difficult to manage. The SWM7000 series helps man-

age such potential complexity with four strategies and/or system accesso-

ries:

1. First, the SW72 and SW72-NDR receivers offer a 50% space-saving

advantage with 2-channel receivers that occupy the same 1U space as

single channel receivers. Each channel in a 2-channel system shares

the true diversity operation of the two antennas connected to the single

receiver chassis.

2. Second, the optional SWA6SS (six-system antenna distribution ampli-

fier) greatly reduces the complexities of multiple receiver antenna de-

ployment. Since each receiver has two (diversity) antennas, which can

be mounted on either the rear or front panel, multiple receivers at one

location can potentially create a forest of antennas protruding from the

front or back of a rack. The SWA6SS Antenna Distributor reduces the

number of antennas to as few as 1/6 what would otherwise be needed.

An added important advantage of using the SWA6SS is its distributed

signal boost provided to all the antenna outputs, delivered while main-

taining diversity in all attached reception channels.

3. Third, large installations often entail long distances from transmitters

to receivers, or the presence of obstacles (walls, for example) in the

transmission path that can interfere with clear reception. While the

SWM7000 series is designed to minimize these kinds of problems

without accessories, the SWASS-EXT (set of two extension antennas,

shown in figure 12b on page 36) may prove helpful or even necessary

in some situations. In addition to providing remote and/or desirable

low profile positioning with improved reception, the SWASS-EXT also

adds another 18 dB of antenna gain for even more reliable system

performance. The Extension Antenna and Distribution Amplifier com-

ponents are also designed to operate in tandem, with the Extension

Antenna plugged directly into the amp, which can then feed (via cable)

Multiple Systems Operation

Sabine 2.4 GHz Smart Spectrum® Wireless

the antenna inputs of 6 receivers. A combination of 2-channel receivers

(SW72-R or SW72-NDR), a set (2 pieces) of SWASS-EXT, and one

SWA6SS, would reduce the antenna clutter of 12 transmission chan-

nels to a single pair of extension antennas. See Section 12 for more

information about setup and use of the SWASS-EXT.

4. Fourth, software control for the ND series receivers allows up to 70

receiver channels to be controlled from a single computer. This quick

and powerful control methodology means you can monitor and change

transmission channels, mic modeling, compression and de-essing —

in short, all front panel controls — from a remote laptop or desktop. In

addition to simplifying multiple unit operation with remote front panel

controls, the remote software provides additional features and func-

tions not available from front panel control. See Section 13 for more

information about setup and use of the Remote Software.

11.2. Antenna Distribution Amplifier

Sabine’s optional accessory SWA6SS Antenna Distribution Amplifier is ideal

for simplifying antenna set up when multiple receivers are used, by using a

single pair of antennas to replace pairs for up to 6 different receivers. Standard

equipment packed with each Antenna Distributor includes an AC power cable,

and 6 pairs of 1-meter long jumper cables (RG-58 AU foam core) for connect-

ing the Antenna Distributor to receivers (2 cables provide true diversity recep-

tion to each receiver).

For best results, the Antenna Distribution Amplifier should be positioned close

enough to the receivers to minimize cable runs. In most applications, you can

use the standard Sabine 2.4 GHz antennas supplied with any of the receivers

to connect to the terminals on the Antenna Distributor, and then connect (in

matching pairs) the jumpers to all your receiver antenna connections (up to 6

receivers, 1 pair per receiver).

Care should be exercised when using longer cables, due to possible trans-

mission signal loss (approximately 1.7 dB/meter). Using the “rule-of-thumb”

that a signal loss no greater than 6 dB will prove acceptable in many circum-

stances, you may be able to use RG-58 cable up to 3 meters or so in length.

However, a better strategy than moving the Antenna Distributor to a better

position, and risking excessive transmission loss back to the receivers or

requiring an upgrade to more expensive cable, is to utilize a pair of Sabine

Extension Antennas (SWASS-EXT). These will connect to the antenna inputs

of the Antenna Distribution Amplifier, and offer increased range, better rear-

source RF rejection, an expanded 180 degree forward sensitivity, flexible mount-

ing options, and signal boost (see Section 12).

For more details regarding specifications and operation of the SWA6SS An-

tenna Distribution Amplifier, please refer to the operating guide included with

that product.

12. EXTENSION ANTENNAS

12.1. Overview

Sabine’s SWM7000 series receivers are designed for easy interface with

Sabine’s SWA-SSEXT Extension Antenna Kit (figure 12b). This triangular, at-

tractive wood-grained unit is designed to mount easily and unobtrusively on a

wall (allowing either a through-the-wall or out-the-bottom connection), or (by

threading) atop a microphone stand for a more portable or temporary position-

ing. Each package contains 2 Extension Antennas, all necessary mounting

hardware (screws and mic stand thread connectors) and both right-angle and

straight connectors for mating with RG-58 cable (for connections to a receiver

or Antenna Distribution Amplifier).

12.2. Antenna Cabling & Cable Loss

While an extension antenna affords the opportunity to increase the distance

from transmitter to receiver, there is a loss of signal in the interconnecting

cable that limits that distance. The maximum connection length is determined

by the type of cable used, and the degree of signal attenuation acceptable.

Let’s presume that an acceptable degree of loss over the total cable run is 6

dB. Without external signal boosts, the different cables shown in the table

would then allow maximum lengths ranging from less than 4 M (RG-58) to 24

M (RG8/U). Thus, for a passive extension antenna, your choices are to limit the

cable run, or increase your budget and buy the more expensive, thicker cable.

Fortunately, Sabine’s SWASS-EXT Active Extension Antenna offers a far better,

more cost-effective solution, due to its built-in active 18 dB signal boost. In the

case of low-cost RG-58 cable, adding an SWASS-EXT to your setup increases

the acceptable maximum cable run by more than 4 times, to 14 meters. With

RG-8 cable, the maximum length is extended to 88 meters!

Power for the Extension Antenna is delivered from any Sabine SWM7000 se-

ries receiver or SWA6SS Antenna Distribution Amplifier (see Section 11).

An additional advantage of using Sabine’s SWASS-EXT Extension Antenna

stems from its more focused, directional nature. Sabine receiver’s coaxial

dipole antennas (standard equipment that mount directly on the front or rear

panels of the receiver or SWA6SS) are more omni directional in nature. In

contrast, the Sabine’s Extension Antenna is sensitive to RF reception in a 180-

degree arc in front of its mounted position. It extends sensitivity to the front and

off-axis side locations as it increases rear RF rejection.

The multiple functions (relocation of antenna, boost of signal, directional sen-

sitivity) of Sabine’s Extension Antenna mean there are many applications in

which its addition to your system can greatly enhance performance. Here’s a

short list of such applications:

37 Sabine 2.4 GHz Smart Spectrum® Wireless

E-SWM7000-OpGuide-031211.pmd - hto

1. Antenna repositioning. Provides solutions when receiver placement op-

tions are limited or challenging. Sabine’s Extension Antenna’s multiple

mounting options allow higher placement (wall mount or microphone stand

mount).

2. Barriers interrupting transmission. Anytime a barrier interferes with trans-

mission and reception, Sabine’s SWA-SSEXT can be mounted on the trans-

mitter side of the barrier with cable connections made on the receiver side.

Perhaps the most common situation of this nature would arise when re-

ceiver and transmitter are located in separate rooms.

3. Expanded or directional sensitivity required. Sabine’s Extension An-

tenna picks up in a 180-degree arc, focused towards the front. Reception

in this arc is enhanced.

4. Rear RF rejection required. Because Sabine’s Extension Antenna is less

sensitive to signals received from the rear, it can be positioned to reject any

such directional RF interference.

5. Extended operational range. Given a potential maximum cable length of

almost 100 meters from Extension Antenna to receiver, Sabine’s SWASS-

EXT allows more options for extending the distance between transmitter

and receiver. (It should be noted that the typical range of Sabine’s SWM7000

series systems without the Extension Antenna is already 100 meters in

typical circumstances). Consider that RF signal strength through the air is

diminished by the square of the distance (twice as far away = ¼ the signal

strength), while signal loss through cable is (roughly) inversely propor-

tional (twice as far away = ½ the signal). That means you can use an

extension antenna to replace transmission-through-air with transmission-

through-cable, to help minimize signal loss.

The SWASS-EXT provides the following benefits:

• Wall mount or mic-stand mount

• Straight and right angle TNC connectors

• 180 degree reception pattern

• +18 dB boost in RF

• Matched pairs

• Wood-tone finish

• Phantom-powered from either the receiver or the distribution amp

13. REMOTE CONTROL OPERATION

13.1. Overview

In many circumstances you will adjust and control your Sabine SWM7000

wireless microphone system using the front panel controls, as outlined in

previous sections of this operating guide. In circumstances where an en-

hanced level of control over a single receiver is desired, or to enable simulta-

neous computer-based control of multiple receivers, you will need to install

(on either a laptop or desktop computer) the free Sabine SWM Remote Control

Software included with your system. Only receivers may be remotely con-

trolled; handheld and belt pack transmitters cannot be remotely controlled.

For online instructions for any function in the software, you may also refer to the

Help menu.

13.1.1. Single vs. Multiple Receiver Control

All SWM7000 series receivers have an RS-232 9-pin serial COMM Port and a

USB port. Thus, any single receiver can be controlled remotely. Control over

multiple receivers from a single computer is possible only with ND-series

receivers (SW71-NDR and SW72-NDR). These units have additional RS-485

network connections (RJ-45 jacks) for daisy-chain connection from one re-

ceiver to the next. Up to 35 receivers (70 transmission channels if all receivers

are 2-channel) may be connected in this network, all under the control of a

single computer. Single- and dual-channel receivers can be mixed in the same

network. The first receiver in such a network can be connected to the computer

via an RS-232 9-pin serial cable or USB cable. The remaining units connect

via an RS-485 cable.

NOTE: It is not possible to upgrade/retrofit a standard receiver to make it an

ND-series unit.

13.1.2 Features & Controls Added Software

All front panel controls and displays are duplicated in the software. In addi-

tion, a deeper level of software control over receiver operation is enabled.

These new controls are complete and independent for each transmission/

reception channel, meaning there are two sets of controls for dual channel

receivers. These controls and displays include:

• Parametric filter access and control. FBX filters can be changed to

parametric filters, and their width, depth, and frequency can be adjusted.

Changes can be made at any time, both before and after FBX filters

have been set. Parametric and FBX filters can be mixed in any combi-

nation, totaling 10 for each receiver channel.

• Adjustable FBX parameter control. Maximum depth of FBX filters can

be adjusted globally; filter width can be adjusted globally or individually.

Two controls, Sensitivity and Persistence, can be tweaked to tailor the

operation of automatic FBX filter placement to match the audio pro-

gram. Proper settings will optimize the balance between false filtering

and delayed response to feedback (the factory default settings should

operate excellently in the vast majority of conditions and may never

need to be changed).

• Control over balance of FBX Fixed and Dynamic filters. Any FBX filter

can be set to be either fixed or dynamic.

• Adjustable high and low cut filters. (Software only) High Cut Filter, user

controllable between 3 KHz and 20 KHz, 12 dB/octave roll-off; Low Cut

Filter user controllable between 20 Hz and 1 KHz, 12 dB/octave roll-off.

• Additional compressor controls. Aside from adjustments for ratio,

threshold, and attack (which duplicate front panel controls), the Remote

Software provides control of compressor release time and knee. The

effect of compression on the output signal as a function of input signal

strength and parameter settings is displayed in Sabine’s unique dy-

namic ColorComp graph, in addition to the traditional opposing-meter

indicators.

Remote Control Operation

NOTE: Some SWM7000 receivers

may not have a USB port. In this

case, simply use a USB to RS-232

9-pin adaptor. Go to Sabine.com for

a list of suggested adapters.

39 Sabine 2.4 GHz Smart Spectrum® Wireless

E-SWM7000-OpGuide-031211.pmd - hto

• RF Scan and Report, which measures strength for each of the 70 trans-

mission channels, and displays a hierarchical ordering of the clearest,

strongest channels to use during system setup and operation. You can

print a copy of the scan results.

• Additional memory options. In addition to saving presets in receiver

memory, channel configuration settings can be saved to and recalled

from disc or hard drive. All parameter settings made with the remote

control, including adjustments that are not accessible from front panel

controls (e.g., compressor knee and release), are saved with presets.

All software settings stored for each of the 10 presets, including set-

tings not accessible from the front panel, will be loaded whether pre-

sets are recalled by remote control or from the front panel. Note that all

settings made in Off-line/Edit mode can be saved and applied in online

operation.

• Ability to print a report of all parameter settings, creating hard copy

documentation.

• A receiver channel output mute button.

• The ability to custom name each RF channel and receiver. This name

will be displayed in the software only.

• Display of important transmitter status information. In addition to

duplicating the battery charge status, battery warning message, and

transmitter on/off/mute status from the front panel display, the Remote

Software displays the number of hours the battery has been in use, the

frequency midpoint (in GHz) of the transmission channel chosen, the

transmitter pad and low cut filter settings, and a warning indication in

the case of low RF signal strength. For handheld transmitters, the

software display also shows the type of mic capsule in use.

• Improved and expanded operational displays. In addition to organiz-

ing all front panel displays on a single computer screen, the Remote

Software also displays the exact frequency, width, and depth of FBX

filters. The frequency response curve resulting from combined filter

settings (including FBX, parametric, and high and low cut) is graphically

displayed in the software. Frequency response changes imposed by

choosing various microphone models are also shown.

• Customizable front panel lock settings. Software control allows you to

program selective access to front panel controls to be made available

once the Remote Control is disconnected. Customizable front panel

lock settings are saved and recalled as part of each receiver’s settings.

All software-only accessible settings are saved with presets. Careful

programming enables some powerful operational features — for ex-

ample, locking Program Save but enabling other front panel controls

(including Program Load) will let front panel users update settings tem-

porarily, yet reload the original settings at the push of a button. Such a

temporary adjustment would not permanently alter a setup designed to

work in most situations, but would allow tweaking to address unusual

situations.

Remote Control Operation

WARNING:

BEFORE DISCONNECTING RECEIVER FROM COMPUTER

Quit all SWM7000 Software functions and close software BEFORE disconnecting the receiver connection to you computer.

Failure to do this may cause the receiver to lock up. In case of receiver lock up, restart receiver.

Sabine 2.4 GHz Smart Spectrum® Wireless

13.1.3. Software Multiple Unit Control

The true extent of the power of the SWM Remote Software is realized when it

is used to control multiple wireless receivers. When ND-series receivers

are connected in a network, the additional controls offered by the Remote

Software over the entire system include:

• Simultaneous multiple channel/system monitoring. The Remote Soft-

ware “All Channel View” (figure 13h) shows all important status condi-

tions for up to 70 transmission channels. Color-coded warnings and

alerts draw attention to potential problems.

• Detailed, quick access to a single set of controls. The “Command

View” (figure 13c) displays comprehensive information about a single

selected RF channel, and easy adjustment of all its controls. Channels

are selected by clicking the appropriate All Channel View button. (NOTE:

Each channel display in the All Channel View also allows quick access

to parameter adjustments, by using the right mouse button to popup a

parameter control menu.)

• Quick, interactive control of wireless network channels. All or se-

lected parameter settings for a given channel can be copied to one or

more additional channels, using the Copy Parameters option.

13.2. Software Installation

13.2.1. Requirements & Recommendations

• PC Minimum Requirements: Pentium 266 MHZ CPU or AMD Duron

CPU; 128 Megabytes of RAM; 20 Megabytes free space on hard drive;

Windows 95 or higher.

• PC Recommended Requirements: Pentium 1.0 GHZ CPU or AMD

Athlon CPU; 512 Megabytes of RAM; 20 Megabytes free space on hard

drive; Windows 2000 or XP.

•SVGA or greater resolution graphic card and monitor. Recommended

minimum monitor resolution: 1024 x 768 pixels (or 800 x 600 pixels for

15 inch monitors). Select “small fonts” and 16 bit color as defaults for

monitor display. Windows XP users select 96 dpi screen settings.

•USB or Serial COMM Port.

13.2.2. Connections

There are three types of connections that are used in a remote controlled

one-or two-channel Sabine SWM7000 system:

•Serial port (RS-232 9-pin): Use this to connect to a single receiver, or

the first receiver in a network (multiple receivers). Be sure to use a cable

with standard 9-pin D-connectors (male on one end, female on the

other) that is a “serial,” not a “null modem” cable.

•USB: Use this to connect to a single receiver, or the first receiver in a

network (multiple receivers).

NOTE: Some SWM7000 receivers may not have a USB port. In this

case, simply use a USB to RS-232 9-pin adaptor. Go to Sabine.com for

a list of suggested adapters.

• Network (multiple SWM7000-ND series receivers):

1. Connect the first receiver in your network to the PC using a USB cable

or an RS-232 Serial Cable (not supplied).

2. Connect all other receivers as a chain using RS-485 (or standard

Ethernet) cables. There are two such jacks on the back of all ND-series

receivers. Either jack can connect to another receiver either “upstream”

or “downstream” from the computer remote control. As signals travel in

both directions (from computer to receiver and back), it is not necessary

to connect the last receiver in a network back to the computer (you do not

need to make a “loop”).

3. IMPORTANT: Set dip switch #7 on the back of the first receiver to the

“OFF” (down) position (default). Set dip switch #7 on all other networked

receivers to the “ON” (up) position.

4. When all cable connections have been made, open the SWM7000

Remote Control Software program on your PC. The SWM7000 software

will find all the receivers in the network and show them in a dialog box

(receiver sequence can be reordered). Click “Accept” to control the net-

work. NOTE: Up to 35 2-channel (or 1-channel, or any combination

thereof) receivers – totalling up to 70 transmission channels – can be

connected in a single network to a single PC.

13.2.3. Installing the Software

Follow these simple instructions for installing the Sabine SWM Remote Soft-

ware on your computer:

1. Insert the Sabine software CD into your PC’s CD ROM drive and wait a

few seconds for the auto-start software installer to open.

2. Select the SWM7000 Remote Control Software installation icon and

follow the instructions given in the dialog boxes that appear. NOTE: For

best results, allow the installation program to install the software within

the default directories.

13.3. Launching the software

Launching the software produces the Startup Screen (Fig. 13a).

13.3.1. Off-Line Edit/Demo

Clicking the right button (“Off-Line Edit/Demo”) will open the main software

screen regardless of whether any SWM receivers are connected. The soft-

ware functions in Off-Line mode are completely programmable, and may be

saved and downloaded to a connected receiver at a later time. Display

settings (e.g., level, compression, transmitter settings) which are depen-

dent on the presence of actual signal are simulated, for demonstration only.

You may turn the simulated displays on or off using the OPTIONS menu.

13.3.2. Connecting Receivers.

Clicking “Connect Receiver” will direct the software to poll the bus on the

designated COMM Port to detect connected, powered-on receivers. If no

receivers are detected, you may change the designated COMM Port by click-

ing the appropriate button. If this also proves ineffective, check your cables

and connections, and make sure the connected receivers are powered on.

In very rare instances you may need to reset your COMM Port settings on your

computer.

Once polling is completed, the software will display all the receivers de-

tected, in sequence, and the model of each receiver (ND series or standard,

1 or 2-channel). (See figure 13b for a sample opening display)

Once you confirm that the information reported is correct, proceed to the

main screen, and you may begin remote control operation.

13.4.1. Two Views, Two Sets of Controls

The default main screen appears

as shown in figure 13c.

The top portion of the screen

(above the “Active Channels” bar

and two arrow buttons) is the

Command View, showing details

and allowing parameter adjust-

ments for a single receiver chan-

nel at a time.

The bottom portion (below “Active

Channels”) is the All Channel View,

capable of simultaneously show-

ing the most important (but less

detailed) information for multiple

channels. Each audio (RF) chan-

nel in the system has its own dis-

play box, arranged in rows of eight

channels each, organized in order

to correspond to the string of re-

ceivers in the serial bus.

If you have 8 or fewer RF channels, both View Modes will fit on your monitor.

For more than 8 channels, there are quick shortcuts for optimizing your dis-

play and switching and mixing View Modes:

• Click and drag the Active Channel bar to pull the All Channel View up or

down, partially or completely covering the Command View. You cursor

will change to a hand icon.

• Use the up/down arrows flanking “Active Channel” to scroll the rows

displayed in the space allocated to the All Channel View.

• Click on the Command View or All Channel View button in the upper left

menu bar (or use F2 and F3), to immediately change from one to the

other.

• To select a channel to edit in either view, left click on a channel in All

Channel View (indicated by a red border around the selected channel).

This displays the selected channel’s settings in the Command View. A

right mouse click on a single channel shown in the All Channel View

pops up a menu of parameters (see figure 13d). The value of the

parameter selected is displayed in the All Channel View for each RF

channel, and also pops up an adjustment screen for the selected chan-

nel. You can review and compare settings on all channels, one param-

eter at a time, and adjust any setting on any unit from the All Channel

View.

• Parameter adjustments in the Command View can be made by clicking

and turning any knob; or by a right-clicking on a parameter to pop up an

adjustment window, and keying in a value.

13.4.2. Menus, Icons & Hot Keys

Quick access to the features described above, plus some additional soft-

ware control, is available from four pull-down menus (File, Select Receiver,

Options, and RF Scan) and five icons (FBX, Lock, Command View, All Chan-

nel View, and RF Scan) at the top of the screen. The controls associated with

the five icons can also be accessed using function keys F2 through F6,

respectively. Figure 13e shows the location of the menus and icons, and

describes associated controls which are accessed.

13.4.2.1. FBX Settings (F4)

Allows global settings of FBX filter width and maximum allowed FBX

filter depth. As filters are set, they will conform to the global width cho-

sen at the time of setting. It is thus possible to mix filter widths by

changing the width value in between setting FBX filters. Maximum depth

will be common to all FBX filters, and the value will update if the global

setting is changed.

Sensitivity and Persistence are controls that allow the speed and analy-

sis of the FBX algorithm to match the type of audio program. Some

audio programs, notably certain types of classical music, produce oc-

casional waveforms that are difficult to distinguish from acoustic feed-

back. The factory default Sensitivity and Persistence values should

work in almost all conditions; however, you may change them if neces-

sary to prevent the possibility of triggering a false filter, or to more quickly

set the FBX filters. There is a trade-off between speed of filter place-

ment and how carefully the filter is placed. More demanding audio

sources may require higher Sensitivity & Persistence settings, which

will slightly slow down the speed of filter placement, but decrease any

possibility of mistaking program audio for feedback.

FBX Dynamic Filter Time Out This function gives each dynamic filter a

time limit, after which the filter automatically resets. A setting of “zero”

disables the timer.

13.4.2.2. Lock (F5)

You can customize the mix of functions that

will be locked when choosing Front Panel Lock

2 (figure 13g). Front Panel Locking can only be

activated using the Dip Switches on the re-

ceiver back panel. See Appendix D for more

information.

13.4.2.5. RF Scan (F6)

Use the RF scan to get a “picture” of the potential RF interference in your

location. You should perform a scan before every program so you can

see the ambient RF levels on all

70 channels of your system.

Caution: The RF Scan mutes and

takes control of the selected chan-

nel. All other functions are dis-

abled on the selected channel. Do

not perform an RF scan on a chan-

nel you need during your pro-

gram!

Select RF Scan by using the toolbar

button, the F6 hot key, or the RF

Scan menu item. You will see the

screen shown in Figure 13i. Se-

lect Single Scan or Continuous

Scan if you want to look at the RF

levels over time. The software will

take control of the selected receiver,

and will step through all 70 chan-

nels. You can control the speed of

the scan using the Dwell Time ad-

justment.

Scan results are shown in several ways. A thick green line indicates a

Sabine transmitter is active on the associated channel. Thin green lines

on either side of that line show RF signal levels for left and right anten-

nas respectively. This RF Diversity function is especially useful for an-

tenna positioning when using distribution amp. A red line indicates

ambient RF is present on the channel, at a level indicated by the scale

on the left side of the chart. A dotted red line indicates a previous RF

level from an earlier scan, and a small yellow “T” indicates the peak RF

level observed over the entire time. Left click on any line or channel

number brings up the “RF Scan data history” window, allowing you to

disable the specific channel (figure 13J). If you chose Continuous Scan

you can also choose to see the Channel Details (figure 13k) and a

history of all RF activity on a particular channel for the duration of the

Continuous Scan (figure 13k).

Channels with very low RF signals (below -70 dBm) should be consid-

ered open channels. We include this low level measurement so you

can see the activity in your location, but the Sabine transmitters will

overpower and ignore those very low signals.

You can choose to disable all chan-

nels with ambient RF levels above

a selectable threshold. Click and

drag the dotted horizontal purple

line to change the threshold (fig-

ure 13i). Choose Block Channels

to disable channels above the

threshold. These channels will no

longer be available when select-

ing RF channels from the front

panel of the receiver.

14. TIPS & TROUBLESHOOTING

14.1. Tips for Maximum Performance

• Keep a clear and unobstructed path between transmitter and receiver.

• Position receiver antennas at least one meter off the performance floor

level.

• Avoid placing receiver antennas near large metallic or other dense

materials.

• Keep receiver antennas away from RF signal generating equipment

(computers, high-voltage equipment, etc.).

• Position antennas perpendicular to each other.

• Use a Sabine Antenna Distribution System (SWA6SS) for multiple sys-

tem installation.

• Return transmitters to a charger when not in use.

• Use a Sabine SWASS-EXT Extension Antenna to extend range and/or

improve reception.

14.2. Troubleshooting

Problem: True Mobility receiver and transmitter power are on, receiver RF

Signal meters and Input Level meters are lighting up, but there is

no sound from system.

Solution: Check connection between receiver and mixer/amp. Adjust re-

ceiver Output Level control. Check for MUTE status in Remote

Control Software. Make sure RF scanner is OFF.

Problem: True Mobility receiver and transmitter power are on, but receiver

RF Signal meters and Input Level meters are not lighting up.

Solution: Check transmitter On/Battery Indicator. Recharge transmitter if

necessary. Check transmitter and receiver frequency Channel

settings (make sure they match). Check receiver antenna con-

nections. Check distance between transmitter and receiver an-

tennas and possible obstructions in path.

Problem: Transmitter is on, but sound is noisy.

Solution: Check transmitter On/Battery Indicator. Replace weak battery with

fresh battery from charger unit if necessary. Check for other

sources of RF interference (high voltage equipment, lighting

equipment, etc.). Check distance between transmitters and re-

ceiver antennas.

Problem: Transmitter is off, but noise still coming from receiver.

Solution: Check for other sources of RF interference (high voltage equip-

ment, lighting equipment, trolley cars, etc.). Select another fre-

quency. Check connection and position of the receiver antennas.

Utilize a Sabine Extension Antenna.

Problem: Noise or humming.

Solution: Check for fluorescent lights — bad ballasts may cause noise or

hum in your system.

Problem: “ERROR 1” message displays on receiver:

Solution: Make sure that the #1 dip switch (located on the rear panel of the

receiver) is in the down (OFF) position.

14.3. Common Sources of RF Interference

Since Marconi and others pioneered the first radio broadcasts, the radio spec-

trum has become increasingly crowded with a huge diversity and variety of RF

sources. The strength, frequency, location, and timing cycles of these RF

sources create a shifting pattern of interfering and overlapping frequencies

and coverage patterns, which can render the use of radio microphones a

difficult and unpredictable business.

The typical sources of interference for conventional wireless mics can be high-

powered broadcasters such as radio stations and TV transmitters, or other

short-range wireless devices, including multiple radio microphones operat-

ing at the same location (either by design, or by coincidence), that operate in

proximate (or harmonically related) bands. Less commonly, interference may

arise from spurious outputs emitted by electronic equipment (notably comput-

ers, printers, or similar devices with digital clocks), faulty electrical equipment,

neon signs, dimmers and lighting controllers, and so forth.

Many UHF and VHF mics are especially vulnerable because they share the RF

spectrum with the very high-powered transmitters for television. The coming

conversion to digital and high-definition broadcast will increase the problems

for UHF and VHF.

The 2.4 to 2.4835 GHz frequency band is not only well above the fundamental

(nominal) transmission frequencies of such strong analog and digital broad-

casts, but also high enough to escape interference problems occurring at the

strong first harmonic of even the highest digital television broadcast. The band

is approved worldwide for a variety of uses, including such diverse transmit-

ters as baby monitors, garage door openers, wireless LANs, amateur satel-

lite, cordless telephones, etc. Compared to RF broadcast sources like televi-

sion and radio stations, these low power devices produce very localized, short

range interference; furthermore, many of the devices working in the 2.4 GHz

range use spread spectrum transmission and reception. Both of these facts

mean such uses of the RF spectrum are less likely to cause interference with,

or suffer from interference from the use of, Sabine’s systems.

14.3.1 RF Sources

Your first step in checking for interference should be utilizing the Scan func-

tion in the SWM7000 Remote Control Software. See Section 13.4.2.5 RF

Scan for a complete discussion of the benefits of scanning, which will reveal

any potential RF sources in your location and allow you to make an informed

choice of channels to use. The scanner can scan for long periods of time

and will give you a report of RF activity over time for each of the 70 channels

available on your Smart Spectrum system.

1. Microwave ovens

In the vast majority of situations, interference from microwave ovens will

not affect performance of your SWM7000 series microphone systems.

Since barriers such as walls work to block interference, a microwave

oven will likely present a problem only when located in fairly close prox-

imity within the same room as the wireless receiver (or reception an-

tenna). See caution below.

Commercial quality microwave ovens present a bigger potential prob-

lem. They sweep over a wider band of frequencies than the limited

band affected by consumer units, and use two magnetron tubes which

alternate to avoid inactivity during a power cycle. Fortunately, Sabine

systems are only affected by such ovens in close proximity to receiver

antennas. That protection, plus the availability of 70 different RF chan-

nels to choose from, makes serious interference problems arising from

microwave ovens avoidable and unlikely. See caution below.

Tips & Troubleshooting

As a general precaution, keep 2.4 GHz cordless telephones, microwave ovens,

WLAN antennas and 2.4 GHz wireless video camera transmitters twice the distance

from your Sabine wireless microphone system antennas as that of your Sabine 2.4

GHz transmitters.

Antenna Placement Caution

Sabine 2.4 GHz Smart Spectrum® Wireless

2. Wireless Local Area Networks (WLANS)

These computer network devices allow computers to connect via wire-

less devices that act as both receivers and transmitters. These low-

powered transceivers often have selectable channels and can utilize

the entire 2.4 GHz band. In general, Sabine microphones should not be

affected by these WLANS because their spread spectrum technology

does not present a problem for the Sabine Smart SpectrumTM system.

The Sabine wireless system will not interfere with the WLAN. See cau-

tion below.

3. Cordless phones

These home telephones broadcast at very low power and should not

present interference problems for your Sabine wireless. This is espe-

cially true if the telephone uses spread spectrum technology. See cau-

tion below.

4. Wireless Video Cameras

Certain wireless video cameras (X10, for example) use the 2.4 GHz

band. These devices are also very low power and, in general, should

not present a problem when using the SWM7000 system. See Section

5 Receiver Operation for methods of optimizing clear reception and

minimizing interference. See caution below.

In the event problems still arise, see Section 5 Receiver Operation for meth-

ods of optimizing clear reception and minimizing interference.

Tips & Troubleshooting

As a general precaution, keep 2.4 GHz cordless telephones, microwave ovens,

WLAN antennas and 2.4 GHz wireless video camera transmitters twice the distance

from your Sabine wireless microphone system antennas as that of your Sabine 2.4

GHz transmitters.

15. FBX THEORY & PRACTICE

15.1. Introduction to FBX®

WHY FBX? Feedback is certainly the most pervasive challenge to the audio

industry. The potential appearance of sudden, loud, out-of-control feedback is

every sound engineer’s and musician’s nightmare. Unlike more subtle audio

quality problems or shortcomings, feedback is embarrassingly obvious — it

disturbs the performer, the audience, and the technician, and can damage

equipment and just generally ruin your day.

Feedback is a potential problem in any amplified sound system that places a

microphone or pickup in proximity to a loudspeaker. Poor acoustical condi-

tions or misguided use by unsophisticated sound system operators only ag-

gravate the situation. To make matters still worse, a non-Sabine variety of

wireless microphone adds yet another level of feedback danger to the picture.

Since feedback erupts whenever the distance, location, and gain relation-

ships between a speaker and a microphone reach a critical combination, a

mic that can move anywhere results in an ever changing potential for feed-

back. A step in the wrong direction may change a clear sound to a piercing

shriek in less than a second.

This enhanced potential for feedback with a wireless system gets worse if

lavalier microphones are used. Such microphones are usually placed farther

from the mouth than handheld or head set microphones, thus requiring more

gain. Also, the polar pattern of a lavalier microphone is frequently omnidirec-

tional. Thus, the likelihood of feedback increases, due to the microphone’s

increased off-axis sensitivity to the sound emanating from the loudspeakers.

The Sabine True Mobility® SWM7000 wireless systems solve feedback prob-

lems by precise attenuation of very narrow bands of feedback-prone frequen-

cies. The process is automatic, simple to use, adaptable to changing acous-

tical conditions and relationships, powerful in its application, and has minimal

consequences to the audio fidelity of the signal. We call this automatic filter an

FBX Feedback Exterminator® filter, or FBX filter for short.

15.2. The Advantages of FBX Filters

Before the invention of FBX, the most common device for controlling feedback

was the 31-band graphic EQ. However, an FBX filter offers three distinct ad-

vantages over graphic filters.

1. First and most obvious is the automatic nature of FBX filters. When feed-

back occurs, FBX responds more quickly than even the most experienced

engineer. Automatic FBX placement works even in the presence of audio

program material, intelligently distinguishing feedback from music or

speech.

2. A second advantage is that FBX micro-filters are precisely placed any-

where feedback occurs (with 1 Hz resolution), while graphic EQ filters are

limited to 31 fixed center points. An FBX filter represents a direct hit on

feedback! In contrast, a graphic EQ filter can only approximate the exact

frequency of the feedback, and the filter (or filters) with the closest center

frequency must be pulled down. Such filters are deepest at their centers,

and such imprecise attenuation takes a big (and unnecessary) chunk out

of your sound (see Fig. 15a).

3. Increased clarity and gain-before-feedback are further accomplished by

the third and most important advantage of FBX: Sabine’s micro-filters are

ten times narrower than 31-band EQ filters. Using FBX micro-filters will

return up to 90 percent of the power removed by EQ filters.

Here’s a good place to make a very important distinction. Graphic EQ filters

are typically called “1/3-octave,” but it’s important to understand that this term

refers to the spacing of the filter centers (1/3-octave apart), and not the width of

the filter (usually a full octave). Graphic filters thus overlap one another, and

affect frequencies well above and below the center point frequency, including

frequencies of adjacent bands. This makes graphic equalizers very practical

tools for shaping sound “with broad strokes,” such as dialing in overall system

EQ, but results in destructive audio quality overkill when they are used to elimi-

-10 dB cut at 500, 630, 1K, 1.25K, 1.6K & 2K Hz

If the graphic EQ really had 1/3 octave filter

widths, the frequency response curve would vary

6 dB between sliders. This would ruin the sound.

Graphic EQs usually use one-octave-wide over-

lapping filters that provide much smoother fre-

quency response curves. Notice that the over-

lapping filters add together to cut -16 dB when

the sliders are only pulled down -10 dB.

Program

FBX Theory & Practice

Sabine 2.4 GHz Smart Spectrum® Wireless

nate feedback. A graphic equalizer would need more than 10,000 narrow-

band sliders to be as precise and powerful as your FBX.

As an example of the power of FBX, figure 15b shows test results measured

with a PA set up consisting of a microphone, mixer, FBX Feedback Extermina-

tor®, power amp and two speakers. The system’s gain was first raised until

the FBX removed nine feedback points. Next, the FBX was replaced with a

graphic EQ. The EQ was adjusted while the system gain was raised to the

same level achieved with the FBX. The frequency response curves of each

device were then plotted and are compared in figure 15b. Note how much

more of the program (the “good audio”) is eliminated using an EQ — whereas

only feedback is eliminated using FBX filters.

15.3. Parametric Filters and FBX

Of course, many savvy sound engineers, realizing the limitations of graphic

equalizers in removing problem feedback, prefer to use a different type of

equalizer, called a parametric EQ, for such applications. If you’re one such

audio engineer, you’ll be comforted to know that FBX filters share much in

common with parametrics.

Compared to graphic filters, parametrics allow more precise adjustments —

specifically, control of filter width, the amount of boost or cut, and the mid-band

frequency of the filter. This greater precision, however, comes at a price, as

parametric filters are not nearly as intuitive or simple to use as graphic equal-

izers.

Nothing, however, is easier to use than an FBX filter, which enjoys the preci-

sion of a parametric filter, yet deploys instantly and automatically whenever

feedback is detected. Effectively, an FBX filter is a parametric filter set to a tenth-

octave width, restricted to cut-only activity, and automatic in its choice of fre-

quency band. If you want hands-on control, use the Sabine True Mobility®

Remote Software to change FBX filters to parametrics, and tweak frequency,

width, and depth to your liking.

Sabine Constant Q Filters

It is common to describe a filter’s quality factor, or “Q,” as the center frequency of the filter divided by the filter width (in Hertz)

measured at the -3dB point. Filters that have the same Q, or width, at the -3dB point regardless of the filter’s cut or boost are called

Constant Q filters (see Fig. 15b). Filters that get wider as the filter gets deeper are called Proportional Q filters (see Fig. 15c). Lately,

however, the definition of Constant Q is becoming less distinct. Many equalizer manufacturers claim their equalizers have Constant

Q filters, when in fact they get substantially wider as they get deeper. The only way to know for sure if the filters are truly Constant

Q is to inspect their frequency response curves. Sabine FBX Filters are true Constant Q filters.

15.3.1. The FBX & True Mobility® Advantage

After inventing FBX technology and refining it for over a

decade, Sabine has brought our patented automatic feed-

back control to its fullest realization with the Sabine

SWM7000 True Mobility® wireless systems. Our latest

advance in maintaining the highest quality audio signal

is due to the placement of the signal processing in the

input chain of the microphone signal. Many times signal

processing (compression and equalization) is placed

after the output stage of a mixer, meaning it is applied to

a combination of inputs mixed together into one output

and passed through the processor. Particularly in the

case of equalization and feedback control, one conse-

quence of such placement is that filtering appropriate to

only one microphone may be applied to all mics in the

same mix bus. In other words, unnecessary filtering

may be applied to microphones that, due to variations in position and micro-

phone characteristics, will feedback at a different set of frequencies. Al-

though the filters are very transparent, why add filtering if you can avoid it?

And why divide your processing power among multiple signals?

Placing the filtering and other signal processing in the input signal path is a

concept called Targeted Input Processing. It means each microphone so

equipped will have customized, unique signal processing applied — and no

unnecessary processing.

With FBX technology, your microphone will finally sound loud enough, every-

one in the audience will understand each word, and feedback will be far less

likely to make an unwelcome and unexpected visit—and you’ll be comfort-

able knowing that protection is extended to anywhere a wireless microphone

might be taken.

14.3.2. FBX Fixed & Dynamic Filters

FBX filters come in two flavors, fixed and dynamic. Both operate automati-

cally. There is no audible difference between fixed and dynamic filters in

terms of sonic purity; the difference arises in their application.

14.3.2.1. Fixed FBX Filters

Once they set automatically (see Section 7 for information on setting

filters), fixed FBX filters will NOT change frequency. You can think of fixed

filters as cures for problem frequencies (the “first-to-feedback” frequen-

cies encountered during normal system operation), common to most

locations in the room.

14.3.2.2. Dynamic FBX Filters

Dynamic FBX filters also set automatically, but can change frequency,

on a rotating basis, as the need arises. To help distinguish dynamic

from fixed filters, consider the example of a speaker using a wireless

lavalier microphone, who walks under a ceiling speaker for the first

time. In so doing, he enters a location-specific feedback zone, where

it’s possible that a problem frequency may have escaped detection and

notching by a fixed filter. If all fixed filters have been deployed, a dynamic

filter will be set automatically as soon as feedback appears, solving the

problem. Great! But what happens when the speaker then moves away

from the ceiling speaker, and close to a floor monitor? Feedback from

the ceiling speaker is no longer a problem, but a new frequency starts to

squeal. If all fixed and dynamic FBX filters are already set, a dynamic

filter will change, to adjust to the new location. An FBX dynamic filter

thus stands guard if new problem feedback arises after all available

filters have been set, providing a deeper and more flexible level of pro-

tection against the dreaded surprise of feedback.

Other than the ability to change frequency, a dynamic filter is equivalent

to a fixed filter.

Sabine 2.4 GHz Smart Spectrum® Wireless

14.3.2.3. Balancing Fixed & Dynamic Filters

Each channel of your SWM7000 wireless receiver offers a total of 10

FBX filters (combined fixed and dynamic), which can be used as needed

to exterminate feedback. After years of experience and experimentation,

Sabine has settled upon a default balance of 7 fixed and 3 dynamic

filters, set at the factory. This default condition can be changed to 8 fixed

and 2 dynamic, by changing a DIP switch on the back of your receiver

(see Appendix D FBX Configuration DIP Switch), or to any configuration

using the Remote Control software (see Section 13).

If you follow setup instructions for setting FBX filters (see Section 7),

your receiver will automatically exit SETUP mode (enter READY status)

after all fixed filters, and the first dynamic filter, have set. In the default

condition, this means you will have set eight filters (seven fixed and one

dynamic), with two dynamic filters still unset and remaining on standby

alert. If you wish to set fewer filters, press the READY button before

SETUP automatically exits, after you have set enough filters to safely

achieve your desired gain level. In that case, in the factory default con-

dition, you will reserve three unset dynamic filters for standby.

14.3.3. FBX Filter Width

Sabine’s experience and testing with filters and sound quality along led us to

decide upon a default FBX filter width of .10 (one-tenth) octave as the optimal

notch width, able to eliminate feedback without affecting music programs. If,

with all filters properly set, feedback is still a problem, FBX filters may be set

to .20 (one-fifth) octave width. This wider filter setting will help to better elimi-

nate feedback trouble areas, but may also affect music programs slightly.

Therefore, the wider setting is generally considered to be appropriate where

speech (less demanding than music) is the primary application of the Sabine

Wireless system. You can globally change FBX filter width by repositioning a

rear panel DIP switch, to change from .10 to .20 octave (see Appendix D FBX

Configuration DIP Switch), or by adjusting filter width using the True MobilityTM

Remote Software (which allows a range of widths from .01 to 1.0 octave).

You may also mix filter widths, either by adjusting individual filter widths

using the Remote Software, or by changing the DIP switch position during

setup. The width of any set filter will always be determined by the position of

the switch at the time the filter is created.

14.3.4. Who Benefits from FBX?

Virtually every sound system will be improved with the Sabine True Mobility®

Wireless System. Singers and speakers who do not have sound techni-

cians can now increase their monitor or house system volume so they can

hear themselves clearly and with full fidelity, without worrying if their micro-

phones will suddenly squeal if they move to the wrong place.

Auditoriums and churches of all sizes will enjoy reliable feedback control.

Hotels and conference centers around the world can offer meeting rooms

with microphones that won’t howl during programs. The Sabine True Mobil-

ity® Wireless System can be installed in theaters, schools, sports arenas,

courtrooms, teleconferencing, intercoms or interactive remote classrooms

— anywhere one or multiple microphones are used.

Appendix G: Changing Audix Mic Capsules (SW70-H)

Sabine's Mic SuperModeling™ function requires a baseline characteristic for the capsule in use. Therefore, after changing

capsules, you will need to “tell” the transmitter which capsule is now attached. NOTE: this is only necessary when the

capsule is changed.

Open the handheld mic’s battery door.

While holding down the SELECT button, turn on the mic. Continue to hold the select button for about

3 seconds, then let go.

One of the screens at right will appear in the transmitter LCD — showing the currently assigned

capsule.

Using the transmitter control up/down buttons, select the capsule you now have attached. Wait a few

seconds until the LCD cycles through the transmitter firmware version numbers and returns to the

default display (channel number).

IMPORTANT: In order for the new capsule selection to be saved, you must now edit the RF channel

selection. To do this, press the Select button, then use the up/down buttons to change the RF

channel. Wait a few seconds to allow the transmitter screen to return to the default display. NOTE: you

can return to the original channel by repeating the channel selection process.

16. CAUTIONS & WARRANTY

Cautions & Warranty

CAUTION - Implanted cardiac pacemakers or AICD devices:

Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wireless microphones have

Iow-power transmitters (less than 0.05 watts output) that are unlikely to cause difficulty, especially if they are at least a few inches away.

However, since a beltpack transmitter typically is placed against the body, Sabine suggests attaching it at the belt, rather than in a shirt

pocket where it may be immediately adjacent to an implanted medical device. Note also that any medical-device disruption will cease

when the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, or

experience any problems with the use of this or any other RF equipment.
