30Sabine 2.4 GHz Smart Spectrum® Wireless8.4. Possible Compression Trouble AreasLike any signal processing, compression can be misused, and improperapplication may cause undesirable side effects in the audio signal. Some ofthese problems include:1. Noise. If the threshold for compression is set too low, and the output gainis raised substantially to make up for the gain loss of compression, theresulting output signal can be noisy. This is because the overall signalmust be raised significantly to produce the same audible level, and thenoise floor of your equipment will be amplified unnecessarily. This prob-lem will be exaggerated if the input signal level to the compressor is verylow (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 floorwill modulate up and down as the audio signal rises above and fallsbelow 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 orspeech has been removed or curtailed. Dynamic variation may be a majorcomponent of a performer’s message and command of the audience;don’t remove dynamics, just control them. This may be particularly true forpercussive musical instruments such as drums.8.5. Release & Knee SettingsTwo other important compressor variables are release time and knee. Re-lease time adjusts the speed with which compression stops and output gainreturns 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 exceedsthe 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, increaseas the input gain crosses the threshold, and reach full compression wellabove the nominal threshold.Values for release time and knee are set at the factory: default release time is250 mSec, and the default knee setting is a “soft” setting of 20. These defaultscan be temporarily changed or reprogrammed using the Sabine True MobilityTMRemote Software (see Section 13 for details).Compressor Limiter

De-mystifying De-essersCertain consonant sounds produced by the human voice contain more energythan others, and have the potential to overload a microphone capsule. Thiscan produce a disproportionately harsh result when amplified through a soundsystem, 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 termfor this particular vocal sound is “sibilance,” and the devices that control suchsounds 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 microphoneitself, and the normal variations in human vocalization. Cardioid- pattern con-denser microphones are especially susceptible to sibilance problems, butthe problem can also occur with other types and patterns of microphones. Therange of frequencies affected by sibilance starts above 2 KHz, and generallytapers 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-esserThe 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 aredetected that correspond to sibilance, a shelving filter is imposed on the ap-propriate frequency bands, and remains in place only for the duration of thesibilance. High frequency energy levels that remain below the comparisonthreshold do not trigger de-essing, and lows and highs outside the sibilancerange are also passed unprocessed and unaffected. This means the SabineDe-esser is effective but transparent.9.3. Using the De-esserUsing 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.Fig. 9a: De-esserDe-esser

With so little to remember, the ability to save andrecall system settings has not been necessary. With the Sabine SWM7000series, however, you get a very sophisticated processor with a variety of adjust-able parameters. The ability to save and recall your carefully programmedsetups can be a tremendous time-saver. Your SWM7000 allows you to storeand recall up to 10 different presets.10.1. Saving a PresetTo 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 toreplace an existing program, press SELECT until you reach that program’snumber. Then press the SAVE button. The function display will show “YES?”.If you are ready to save, immediately press the SAVE button again, and yoursettings will be saved to that program number. The message PRESET SAVEDwill be shown for four seconds in the text display to confirm this action, as theLCD 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 RFchannel.10.2. Loading a PresetLoading 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 andyour 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 PresetPresets, channels and receivers can be named using the Sabine True MobilityRemote Software. Refer to Section 13 for details.10.4. Power Off MemoryThe SWM7000 retains in memory all settings in effect at the time of beingpowered off, and returns to those settings when powered on.Program Save & RecallFig. 10a: Program Front Panel ButtonsFig. 10b: Program SAVE YES?Fig. 10d: Program LOAD YES?Fig. 10c: Program PRESET SAVEDPRESET NOTES 1. Preset 01 is the System Default (SYSDEF on the front panel) and you cannotsave a preset here. Load this setting when you want to return the receiver to thefactory default settings.2.

OverviewIn many circumstances a single wireless microphone system is all that will bein use at any one time. Larger applications (church, concert hall, theaterstage, 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 theinterference problems associated with two or more RF channels at work at thesame time, at the same location.11.1.1. Multiple System InterferenceSabine’s SWM7000 addresses multiple system interference with two strat-egies. First, greater available bandwidth in the 2.4-2.4835 GHz range meansmore channels can occupy the band, i.e., the expanded range can be dividedinto 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 formany more simultaneous transmission channels than conventional UHF orVHF systems.While such performance benefits are one of the major advantages of theSWM7000, more systems working at the same time leads to a greater po-tential for complexity. Fortunately, the SWM7000 also offers tools to simplifysetup and operation.11.1.2. Setup ComplexityMultiple wireless systems in a large installation are of course more compli-cated than a single transmitter/receiver. More space is needed, and thesheer quantity of transmitters and receivers that may be in use at a singleinstallation 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-savingadvantage with 2-channel receivers that occupy the same 1U space assingle channel receivers. Each channel in a 2-channel system sharesthe true diversity operation of the two antennas connected to the singlereceiver 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 canbe mounted on either the rear or front panel, multiple receivers at onelocation can potentially create a forest of antennas protruding from thefront or back of a rack. The SWA6SS Antenna Distributor reduces thenumber of antennas to as few as 1/6 what would otherwise be needed.An added important advantage of using the SWA6SS is its distributedsignal 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 transmittersto receivers, or the presence of obstacles (walls, for example) in thetransmission path that can interfere with clear reception. While theSWM7000 series is designed to minimize these kinds of problemswithout accessories, the SWASS-EXT (set of two extension antennas,shown in figure 12b on page 36) may prove helpful or even necessaryin some situations. In addition to providing remote and/or desirablelow profile positioning with improved reception, the SWASS-EXT alsoadds another 18 dB of antenna gain for even more reliable systemperformance. The Extension Antenna and Distribution Amplifier com-ponents are also designed to operate in tandem, with the ExtensionAntenna plugged directly into the amp, which can then feed (via cable)Multiple Systems Operation
34Sabine 2.4 GHz Smart Spectrum® Wirelessthe antenna inputs of 6 receivers. A combination of 2-channel receivers(SW72-R or SW72-NDR), a set (2 pieces) of SWASS-EXT, and oneSWA6SS, would reduce the antenna clutter of 12 transmission chan-nels to a single pair of extension antennas. See Section 12 for moreinformation about setup and use of the SWASS-EXT.4. Fourth, software control for the ND series receivers allows up to 70receiver channels to be controlled from a single computer. This quickand powerful control methodology means you can monitor and changetransmission channels, mic modeling, compression and de-essing —in short, all front panel controls — from a remote laptop or desktop. Inaddition to simplifying multiple unit operation with remote front panelcontrols, the remote software provides additional features and func-tions not available from front panel control. See Section 13 for moreinformation about setup and use of the Remote Software.11.2. Antenna Distribution AmplifierSabine’s optional accessory SWA6SS Antenna Distribution Amplifier is idealfor simplifying antenna set up when multiple receivers are used, by using asingle pair of antennas to replace pairs for up to 6 different receivers. Standardequipment 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 closeenough to the receivers to minimize cable runs. In most applications, you canuse the standard Sabine 2.4 GHz antennas supplied with any of the receiversto connect to the terminals on the Antenna Distributor, and then connect (inmatching pairs) the jumpers to all your receiver antenna connections (up to 6receivers, 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 betterposition, and risking excessive transmission loss back to the receivers orrequiring an upgrade to more expensive cable, is to utilize a pair of SabineExtension Antennas (SWASS-EXT). These will connect to the antenna inputsof 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 withthat product.Multiple Systems Operation

36Sabine 2.4 GHz Smart Spectrum® Wireless12. EXTENSION ANTENNAS12.1. OverviewSabine’s SWM7000 series receivers are designed for easy interface withSabine’s SWA-SSEXT Extension Antenna Kit (figure 12b). This triangular, at-tractive wood-grained unit is designed to mount easily and unobtrusively on awall (allowing either a through-the-wall or out-the-bottom connection), or (bythreading) atop a microphone stand for a more portable or temporary position-ing. Each package contains 2 Extension Antennas, all necessary mountinghardware (screws and mic stand thread connectors) and both right-angle andstraight connectors for mating with RG-58 cable (for connections to a receiveror Antenna Distribution Amplifier).12.2. Antenna Cabling & Cable LossWhile an extension antenna affords the opportunity to increase the distancefrom transmitter to receiver, there is a loss of signal in the interconnectingcable that limits that distance. The maximum connection length is determinedby 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 6dB. Without external signal boosts, the different cables shown in the tablewould then allow maximum lengths ranging from less than 4 M (RG-58) to 24M (RG8/U). Thus, for a passive extension antenna, your choices are to limit thecable run, or increase your budget and buy the more expensive, thicker cable.Extension AntennasFig. 12b SWASS-EXT Mic-stand mount andwall-mount extension antennasRG58 9203 Polyethylene #20 Stranded -16.29 14 TNCRG58/AU 9311 Foam Polyethylene #20 Stranded -11.10 20 TNCRG212/U 9861 Polyethylene #15.5 solid, -6.11 36 NSilver PlatedRG8/U 9913 Semi-solid Polyethylene #10 Solid -2.50 88 NRG142 83242 Teflon #18 Solid, -6.54 34 TNCSilver PlatedCoaxial Cable Attenuation Table - 2.4 GHzFig. 12c Coaxial Cable Attenuation Table10 MeterAttenuation(dB)MaximumPracticalDistance UsingSWASS-EXT(meters)CableType Belden # Insulation CenterConductor ConnectorTypeIMPORTANTAntenna Cabling Impedancemust be 50 Ohm.! !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 thecase of low-cost RG-58 cable, adding an SWASS-EXT to your setup increasesthe acceptable maximum cable run by more than 4 times, to 14 meters. WithRG-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 Antennastems from its more focused, directional nature. Sabine receiver’s coaxialdipole antennas (standard equipment that mount directly on the front or rearpanels of the receiver or SWA6SS) are more omni directional in nature. Incontrast, 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 andoff-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 inwhich its addition to your system can greatly enhance performance. Here’s ashort list of such applications:
37 Sabine 2.4 GHz Smart Spectrum® WirelessE-SWM7000-OpGuide-031211.pmd - hto1. Antenna repositioning. Provides solutions when receiver placement op-tions are limited or challenging. Sabine’s Extension Antenna’s multiplemounting options allow higher placement (wall mount or microphone standmount).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. Receptionin this arc is enhanced.4. Rear RF rejection required. Because Sabine’s Extension Antenna is lesssensitive to signals received from the rear, it can be positioned to reject anysuch directional RF interference.5. Extended operational range. Given a potential maximum cable length ofalmost 100 meters from Extension Antenna to receiver, Sabine’s SWASS-EXT allows more options for extending the distance between transmitterand receiver. (It should be noted that the typical range of Sabine’s SWM7000series systems without the Extension Antenna is already 100 meters intypical circumstances). Consider that RF signal strength through the air isdiminished by the square of the distance (twice as far away = ¼ the signalstrength), while signal loss through cable is (roughly) inversely propor-tional (twice as far away = ½ the signal). That means you can use anextension 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 ampExtension AntennasIMPORTANTActive Electronics AntennaSabine wireless receivers provideantennas with active electronics.

38Sabine 2.4 GHz Smart Spectrum® Wireless13. REMOTE CONTROL OPERATION13.1. OverviewIn many circumstances you will adjust and control your Sabine SWM7000wireless microphone system using the front panel controls, as outlined inprevious 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 ControlSoftware 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 theHelp menu.13.1.1. Single vs. Multiple Receiver ControlAll SWM7000 series receivers have an RS-232 9-pin serial COMM Port and aUSB port. Thus, any single receiver can be controlled remotely. Control overmultiple receivers from a single computer is possible only with ND-seriesreceivers (SW71-NDR and SW72-NDR). These units have additional RS-485network connections (RJ-45 jacks) for daisy-chain connection from one re-ceiver to the next. Up to 35 receivers (70 transmission channels if all receiversare 2-channel) may be connected in this network, all under the control of asingle computer. Single- and dual-channel receivers can be mixed in the samenetwork. The first receiver in such a network can be connected to the computervia an RS-232 9-pin serial cable or USB cable. The remaining units connectvia an RS-485 cable.NOTE: It is not possible to upgrade/retrofit a standard receiver to make it anND-series unit.13.1.2 Features & Controls Added SoftwareAll 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 channelreceivers. These controls and displays include:• Parametric filter access and control. FBX filters can be changed toparametric filters, and their width, depth, and frequency can be adjusted.Changes can be made at any time, both before and after FBX filtershave 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 canbe adjusted globally; filter width can be adjusted globally or individually.Two controls, Sensitivity and Persistence, can be tweaked to tailor theoperation of automatic FBX filter placement to match the audio pro-gram. Proper settings will optimize the balance between false filteringand delayed response to feedback (the factory default settings shouldoperate excellently in the vast majority of conditions and may neverneed to be changed).• Control over balance of FBX Fixed and Dynamic filters. Any FBX filtercan be set to be either fixed or dynamic.• Adjustable high and low cut filters. (Software only) High Cut Filter, usercontrollable between 3 KHz and 20 KHz, 12 dB/octave roll-off; Low CutFilter 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 RemoteSoftware provides control of compressor release time and knee. Theeffect of compression on the output signal as a function of input signalstrength and parameter settings is displayed in Sabine’s unique dy-namic ColorComp graph, in addition to the traditional opposing-meterindicators.Remote Control OperationNOTE: Some SWM7000 receiversmay not have a USB port. In thiscase, simply use a USB to RS-2329-pin adaptor. Go to Sabine.com fora list of suggested adapters.
39 Sabine 2.4 GHz Smart Spectrum® WirelessE-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 canprint a copy of the scan results.• Additional memory options. In addition to saving presets in receivermemory, channel configuration settings can be saved to and recalledfrom disc or hard drive. All parameter settings made with the remotecontrol, including adjustments that are not accessible from front panelcontrols (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 allsettings made in Off-line/Edit mode can be saved and applied in onlineoperation.• Ability to print a report of all parameter settings, creating hard copydocumentation.• A receiver channel output mute button.• The ability to custom name each RF channel and receiver. This namewill be displayed in the software only.• Display of important transmitter status information. In addition toduplicating the battery charge status, battery warning message, andtransmitter on/off/mute status from the front panel display, the RemoteSoftware displays the number of hours the battery has been in use, thefrequency midpoint (in GHz) of the transmission channel chosen, thetransmitter pad and low cut filter settings, and a warning indication inthe case of low RF signal strength. For handheld transmitters, thesoftware 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 RemoteSoftware also displays the exact frequency, width, and depth of FBXfilters. The frequency response curve resulting from combined filtersettings (including FBX, parametric, and high and low cut) is graphicallydisplayed in the software. Frequency response changes imposed bychoosing various microphone models are also shown.• Customizable front panel lock settings. Software control allows you toprogram selective access to front panel controls to be made availableonce the Remote Control is disconnected. Customizable front panellock settings are saved and recalled as part of each receiver’s settings.All software-only accessible settings are saved with presets. Carefulprogramming 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 atemporary adjustment would not permanently alter a setup designed towork in most situations, but would allow tweaking to address unusualsituations.Remote Control OperationWARNING:BEFORE DISCONNECTING RECEIVER FROM COMPUTERQuit 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.

Software Multiple Unit ControlThe true extent of the power of the SWM Remote Software is realized when itis used to control multiple wireless receivers. When ND-series receiversare connected in a network, the additional controls offered by the RemoteSoftware 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 andalerts draw attention to potential problems.• Detailed, quick access to a single set of controls. The “CommandView” (figure 13c) displays comprehensive information about a singleselected RF channel, and easy adjustment of all its controls. Channelsare selected by clicking the appropriate All Channel View button. (NOTE:Each channel display in the All Channel View also allows quick accessto parameter adjustments, by using the right mouse button to popup aparameter control menu.)• Quick, interactive control of wireless network channels. All or se-lected parameter settings for a given channel can be copied to one ormore additional channels, using the Copy Parameters option.13.2. Software Installation13.2.1.

Windows XP users select 96 dpi screen settings.•USB or Serial COMM Port.13.2.2. ConnectionsThere are three types of connections that are used in a remote controlledone-or two-channel Sabine SWM7000 system:•Serial port (RS-232 9-pin): Use this to connect to a single receiver, orthe first receiver in a network (multiple receivers). Be sure to use a cablewith standard 9-pin D-connectors (male on one end, female on theother) that is a “serial,” not a “null modem” cable.•USB: Use this to connect to a single receiver, or the first receiver in anetwork (multiple receivers).NOTE: Some SWM7000 receivers may not have a USB port. In thiscase, simply use a USB to RS-232 9-pin adaptor. Go to Sabine.com fora list of suggested adapters.• Network (multiple SWM7000-ND series receivers):1. Connect the first receiver in your network to the PC using a USB cableor an RS-232 Serial Cable (not supplied).2. Connect all other receivers as a chain using RS-485 (or standardEthernet) cables. There are two such jacks on the back of all ND-seriesreceivers. Either jack can connect to another receiver either “upstream”or “downstream” from the computer remote control. As signals travel inboth directions (from computer to receiver and back), it is not necessaryto connect the last receiver in a network back to the computer (you do notneed to make a “loop”).Remote Control OperationUSB DRIVERSYour USB enabled SWM7000 receiverrequires version 2.0 or above software.Installing this software will also install thenecessary USB drivers onto your com-puter. If at any time you need to re-installUSB drivers, use the software CD sup-plied with your receiver, or download themfrom Sabine.com.NETWORKCABLE CONNECTIONSConnect the first receiver of a networkusing a USB or RS-232 9-pin connection.All subsequent receivers connect to eachother via RS-485 connection.UP: All but the first re-ceiver connected to anetwork.DOWN: First receiverconnected to the net-work.NETWORKDIP SWITCH SETTINGS

Set dip switch #7 on all other networkedreceivers to the “ON” (up) position.4. When all cable connections have been made, open the SWM7000Remote Control Software program on your PC. The SWM7000 softwarewill 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 combinationthereof) receivers – totalling up to 70 transmission channels – can beconnected in a single network to a single PC.13.2.3. Installing the SoftwareFollow 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 afew seconds for the auto-start software installer to open.2. Select the SWM7000 Remote Control Software installation icon andfollow the instructions given in the dialog boxes that appear. NOTE: Forbest results, allow the installation program to install the software withinthe default directories.13.3. Launching the softwareLaunching the software produces the Startup Screen (Fig. 13a).13.3.1. Off-Line Edit/DemoClicking the right button (“Off-Line Edit/Demo”) will open the main softwarescreen regardless of whether any SWM receivers are connected. The soft-ware functions in Off-Line mode are completely programmable, and may besaved and downloaded to a connected receiver at a later time. Displaysettings (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 thedesignated COMM Port to detect connected, powered-on receivers. If noreceivers are detected, you may change the designated COMM Port by click-ing the appropriate button. If this also proves ineffective, check your cablesand connections, and make sure the connected receivers are powered on.In very rare instances you may need to reset your COMM Port settings on yourcomputer.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).

Two Views, Two Sets of ControlsThe default main screen appearsas shown in figure 13c.The top portion of the screen(above the “Active Channels” barand two arrow buttons) is theCommand View, showing detailsand allowing parameter adjust-ments for a single receiver chan-nel at a time.The bottom portion (below “ActiveChannels”) is the All Channel View,capable of simultaneously show-ing the most important (but lessdetailed) information for multiplechannels. Each audio (RF) chan-nel in the system has its own dis-play box, arranged in rows of eightchannels each, organized in orderto 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 ordown, partially or completely covering the Command View. You cursorwill change to a hand icon.• Use the up/down arrows flanking “Active Channel” to scroll the rowsdisplayed in the space allocated to the All Channel View.• Click on the Command View or All Channel View button in the upper leftmenu bar (or use F2 and F3), to immediately change from one to theother.• To select a channel to edit in either view, left click on a channel in AllChannel View (indicated by a red border around the selected channel).This displays the selected channel’s settings in the Command View. Aright mouse click on a single channel shown in the All Channel Viewpops up a menu of parameters (see figure 13d). The value of theparameter selected is displayed in the All Channel View for each RFchannel, 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 ChannelView.• Parameter adjustments in the Command View can be made by clickingand turning any knob; or by a right-clicking on a parameter to pop up anadjustment window, and keying in a value.13.4.2.

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 bychanging the width value in between setting FBX filters. Maximum depthwill be common to all FBX filters, and the value will update if the globalsetting 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. Someaudio 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 shouldwork in almost all conditions; however, you may change them if neces-sary to prevent the possibility of triggering a false filter, or to more quicklyset the FBX filters. There is a trade-off between speed of filter place-ment and how carefully the filter is placed. More demanding audiosources may require higher Sensitivity & Persistence settings, whichwill slightly slow down the speed of filter placement, but decrease anypossibility of mistaking program audio for feedback.FBX Dynamic Filter Time Out This function gives each dynamic filter atime limit, after which the filter automatically resets.

You can control the speed ofthe scan using the Dwell Time ad-justment.Scan results are shown in several ways. A thick green line indicates aSabine transmitter is active on the associated channel. Thin green lineson 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 indicatesambient RF is present on the channel, at a level indicated by the scaleon the left side of the chart. A dotted red line indicates a previous RFlevel from an earlier scan, and a small yellow “T” indicates the peak RFlevel observed over the entire time. Left click on any line or channelnumber brings up the “RF Scan data history” window, allowing you todisable the specific channel (figure 13J). If you chose Continuous Scanyou can also choose to see the Channel Details (figure 13k) and ahistory of all RF activity on a particular channel for the duration of theContinuous 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 youcan see the activity in your location, but the Sabine transmitters willoverpower and ignore those very low signals.You can choose to disable all chan-nels with ambient RF levels abovea selectable threshold.

47 Sabine 2.4 GHz Smart Spectrum® WirelessE-SWM7000-OpGuide-031211.pmd - hto14.3. Common Sources of RF InterferenceSince Marconi and others pioneered the first radio broadcasts, the radio spec-trum has become increasingly crowded with a huge diversity and variety of RFsources. The strength, frequency, location, and timing cycles of these RFsources create a shifting pattern of interfering and overlapping frequenciesand coverage patterns, which can render the use of radio microphones adifficult 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 othershort-range wireless devices, including multiple radio microphones operat-ing at the same location (either by design, or by coincidence), that operate inproximate (or harmonically related) bands. Less commonly, interference mayarise 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 RFspectrum with the very high-powered transmitters for television. The comingconversion to digital and high-definition broadcast will increase the problemsfor 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 thestrong first harmonic of even the highest digital television broadcast. The bandis 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, shortrange interference; furthermore, many of the devices working in the 2.4 GHzrange use spread spectrum transmission and reception. Both of these factsmean 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 SourcesYour 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 RFScan for a complete discussion of the benefits of scanning, which will revealany potential RF sources in your location and allow you to make an informedchoice of channels to use. The scanner can scan for long periods of timeand will give you a report of RF activity over time for each of the 70 channelsavailable on your Smart Spectrum system.1. Microwave ovensIn the vast majority of situations, interference from microwave ovens willnot affect performance of your SWM7000 series microphone systems. Since barriers such as walls work to block interference, a microwaveoven 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 limitedband affected by consumer units, and use two magnetron tubes whichalternate to avoid inactivity during a power cycle. Fortunately, Sabinesystems are only affected by such ovens in close proximity to receiverantennas. That protection, plus the availability of 70 different RF chan-nels to choose from, makes serious interference problems arising frommicrowave ovens avoidable and unlikely. See caution below.Tips & TroubleshootingAs a general precaution, keep 2.4 GHz cordless telephones, microwave ovens,WLAN antennas and 2.4 GHz wireless video camera transmitters twice the distancefrom your Sabine wireless microphone system antennas as that of your Sabine 2.4GHz transmitters.Antenna Placement Caution

49 Sabine 2.4 GHz Smart Spectrum® WirelessE-SWM7000-OpGuide-031211.pmd - hto15. FBX THEORY & PRACTICE15.1. Introduction to FBX®WHY FBX? Feedback is certainly the most pervasive challenge to the audioindustry. The potential appearance of sudden, loud, out-of-control feedback isevery sound engineer’s and musician’s nightmare. Unlike more subtle audioquality problems or shortcomings, feedback is embarrassingly obvious — itdisturbs the performer, the audience, and the technician, and can damageequipment and just generally ruin your day.Feedback is a potential problem in any amplified sound system that places amicrophone 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 ofwireless 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, amic 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 piercingshriek in less than a second.This enhanced potential for feedback with a wireless system gets worse iflavalier microphones are used. Such microphones are usually placed fartherfrom the mouth than handheld or head set microphones, thus requiring moregain. Also, the polar pattern of a lavalier microphone is frequently omnidirec-tional. Thus, the likelihood of feedback increases, due to the microphone’sincreased 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 minimalconsequences to the audio fidelity of the signal. We call this automatic filter anFBX Feedback Exterminator® filter, or FBX filter for short.15.2. The Advantages of FBX FiltersBefore the invention of FBX, the most common device for controlling feedbackwas 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 experiencedengineer. Automatic FBX placement works even in the presence of audioprogram material, intelligently distinguishing feedback from music orspeech.2. A second advantage is that FBX micro-filters are precisely placed any-where feedback occurs (with 1 Hz resolution), while graphic EQ filters arelimited to 31 fixed center points. An FBX filter represents a direct hit onfeedback! In contrast, a graphic EQ filter can only approximate the exactfrequency of the feedback, and the filter (or filters) with the closest centerfrequency must be pulled down. Such filters are deepest at their centers,and such imprecise attenuation takes a big (and unnecessary) chunk outof your sound (see Fig. 15a).3. Increased clarity and gain-before-feedback are further accomplished bythe third and most important advantage of FBX: Sabine’s micro-filters areten times narrower than 31-band EQ filters. Using FBX micro-filters willreturn up to 90 percent of the power removed by EQ filters.Here’s a good place to make a very important distinction. Graphic EQ filtersare typically called “1/3-octave,” but it’s important to understand that this termrefers to the spacing of the filter centers (1/3-octave apart), and not the width ofthe filter (usually a full octave). Graphic filters thus overlap one another, andaffect frequencies well above and below the center point frequency, includingfrequencies of adjacent bands. This makes graphic equalizers very practicaltools for shaping sound “with broad strokes,” such as dialing in overall systemEQ, 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 HzIf the graphic EQ really had 1/3 octave filterwidths, the frequency response curve would vary6 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 whenthe sliders are only pulled down -10 dB.Fig. 15a What a Graphic EQ does to yourProgramFBX Theory & Practice
50Sabine 2.4 GHz Smart Spectrum® Wirelessnate 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 measuredwith 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 untilthe FBX removed nine feedback points. Next, the FBX was replaced with agraphic EQ. The EQ was adjusted while the system gain was raised to thesame level achieved with the FBX. The frequency response curves of eachdevice were then plotted and are compared in figure 15b. Note how muchmore of the program (the “good audio”) is eliminated using an EQ — whereasonly feedback is eliminated using FBX filters.15.3. Parametric Filters and FBXOf course, many savvy sound engineers, realizing the limitations of graphicequalizers in removing problem feedback, prefer to use a different type ofequalizer, called a parametric EQ, for such applications. If you’re one suchaudio engineer, you’ll be comforted to know that FBX filters share much incommon 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-bandfrequency of the filter. This greater precision, however, comes at a price, asparametric 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 wheneverfeedback 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 FiltersIt 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 calledConstant 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 ConstantQ filters, when in fact they get substantially wider as they get deeper. The only way to know for sure if the filters are truly ConstantQ is to inspect their frequency response curves. Sabine FBX Filters are true Constant Q filters.Fig. 15b - Constant Q Filter Fig. 15c - Proportional FilterFBX Theory & Practice

The FBX & True Mobility® AdvantageAfter inventing FBX technology and refining it for over adecade, Sabine has brought our patented automatic feed-back control to its fullest realization with the SabineSWM7000 True Mobility® wireless systems. Our latestadvance in maintaining the highest quality audio signalis due to the placement of the signal processing in theinput chain of the microphone signal. Many times signalprocessing (compression and equalization) is placedafter the output stage of a mixer, meaning it is applied toa combination of inputs mixed together into one outputand passed through the processor. Particularly in thecase of equalization and feedback control, one conse-quence of such placement is that filtering appropriate toonly one microphone may be applied to all mics in thesame mix bus. In other words, unnecessary filteringmay 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 aconcept called Targeted Input Processing. It means each microphone soequipped will have customized, unique signal processing applied — and nounnecessary 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 lesslikely to make an unwelcome and unexpected visit—and you’ll be comfort-able knowing that protection is extended to anywhere a wireless microphonemight be taken.14.3.2. FBX Fixed & Dynamic FiltersFBX filters come in two flavors, fixed and dynamic. Both operate automati-cally. There is no audible difference between fixed and dynamic filters interms of sonic purity; the difference arises in their application.14.3.2.1. Fixed FBX FiltersOnce they set automatically (see Section 7 for information on settingfilters), fixed FBX filters will NOT change frequency. You can think of fixedfilters as cures for problem frequencies (the “first-to-feedback” frequen-cies encountered during normal system operation), common to mostlocations in the room.14.3.2.2. Dynamic FBX FiltersDynamic FBX filters also set automatically, but can change frequency,on a rotating basis, as the need arises. To help distinguish dynamicfrom fixed filters, consider the example of a speaker using a wirelesslavalier microphone, who walks under a ceiling speaker for the firsttime. In so doing, he enters a location-specific feedback zone, whereit’s possible that a problem frequency may have escaped detection andnotching by a fixed filter. If all fixed filters have been deployed, a dynamicfilter will be set automatically as soon as feedback appears, solving theproblem. Great! But what happens when the speaker then moves awayfrom the ceiling speaker, and close to a floor monitor? Feedback fromthe ceiling speaker is no longer a problem, but a new frequency starts tosqueal. If all fixed and dynamic FBX filters are already set, a dynamicfilter will change, to adjust to the new location. An FBX dynamic filterthus stands guard if new problem feedback arises after all availablefilters 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 equivalentto a fixed filter.Fig. 15d - FBX at Work: What FBX Gives Back to your ProgramFBX Theory & Practice
52Sabine 2.4 GHz Smart Spectrum® Wireless14.3.2.3. Balancing Fixed & Dynamic FiltersEach channel of your SWM7000 wireless receiver offers a total of 10FBX filters (combined fixed and dynamic), which can be used as neededto exterminate feedback. After years of experience and experimentation,Sabine has settled upon a default balance of 7 fixed and 3 dynamicfilters, set at the factory. This default condition can be changed to 8 fixedand 2 dynamic, by changing a DIP switch on the back of your receiver(see Appendix D FBX Configuration DIP Switch), or to any configurationusing 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 defaultcondition, this means you will have set eight filters (seven fixed and onedynamic), with two dynamic filters still unset and remaining on standbyalert. If you wish to set fewer filters, press the READY button beforeSETUP automatically exits, after you have set enough filters to safelyachieve 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 WidthSabine’s experience and testing with filters and sound quality along led us todecide upon a default FBX filter width of .10 (one-tenth) octave as the optimalnotch width, able to eliminate feedback without affecting music programs. If,with all filters properly set, feedback is still a problem, FBX filters may be setto .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 wherespeech (less demanding than music) is the primary application of the SabineWireless system. You can globally change FBX filter width by repositioning arear panel DIP switch, to change from .10 to .20 octave (see Appendix D FBXConfiguration DIP Switch), or by adjusting filter width using the True MobilityTMRemote Software (which allows a range of widths from .01 to 1.0 octave).You may also mix filter widths, either by adjusting individual filter widthsusing the Remote Software, or by changing the DIP switch position duringsetup. The width of any set filter will always be determined by the position ofthe 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 canhear 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 roomswith 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.FBX Theory & Practice

Therefore, after changingcapsules, you will need to “tell” the transmitter which capsule is now attached. NOTE: this is only necessary when thecapsule 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 about3 seconds, then let go.One of the screens at right will appear in the transmitter LCD — showing the currently assignedcapsule.Using the transmitter control up/down buttons, select the capsule you now have attached. Wait a fewseconds until the LCD cycles through the transmitter firmware version numbers and returns to thedefault display (channel number).IMPORTANT: In order for the new capsule selection to be saved, you must now edit the RF channelselection. To do this, press the Select button, then use the up/down buttons to change the RFchannel. Wait a few seconds to allow the transmitter screen to return to the default display. NOTE: youcan return to the original channel by repeating the channel selection process.Audix OM-3Audix OM-512345

CAUTIONS & WARRANTYCautions & WarrantyCAUTION - 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 haveIow-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 shirtpocket where it may be immediately adjacent to an implanted medical device. Note also that any medical-device disruption will ceasewhen the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, orexperience any problems with the use of this or any other RF equipment.Japan 100 VACU.S./North America 120 VACContinental Europe 230 VACUnited Kingdom 240 VACAustralia 240 VACJapanese EMI Compliance StatementThe True Mobility is designed to operate from standard AC power.Please be sure the power in your area is compatible with thepower requirements marked on the rear of the unit.
