Digital Hybrid Wireless Belt-Pack Transmitters
Introduction
The design of the SMWB transmitter delivers the advanced technology and features of Digital Hybrid Wireless® in a Lectrosonics belt-pack transmitter at a modest
cost. Digital Hybrid Wireless® combines a 24-bit digital
audio chain with an analog FM radio link to eliminate a
compandor and its artifacts, yet preserve the extended
operating range and noise rejection of the finest analog wireless systems. DSP “compatibility modes” allow
the transmitter to also be used with a variety of analog
receivers by emulating the compandors found in earlier
Lectrosonics analog wireless and IFB receivers, and
certain receivers from other manufacturers (contact the
factory for details).
The housing is a rugged, machined aluminum package.
The input jack is a standard Lectrosonics 5-pin type for
use with electret lavaliere mics, dynamic mics, musical instrument pickups and line level signals. The LEDs
on the keypad allow quick and accurate level settings
without having to view the receiver. The unit is powered
by two AA batteries. The antenna port uses a standard
50 ohm SMA connector.
The switching power supplies in the provide constant
voltages to the transmitter circuits from the beginning to
the end of battery life, with output power remaining constant over the life of the battery. The input amplifier uses
an ultra low noise op amp. Input gain is adjustable over
a 44 dB range, with a DSP-controlled dual envelope
input limiter providing a clean 30 dB range to prevent
overload from signal peaks.
About Digital Hybrid Wireless®
All wireless links suffer from channel noise to some
degree, and all wireless microphone systems seek to
minimize the impact of that noise on the desired signal.
Conventional analog systems use compandors for
enhanced dynamic range, at the cost of subtle artifacts
(known as “pumping” and “breathing”). Wholly digital
systems defeat the noise by sending the audio information in digital form, at the cost of some combination of
power, bandwidth, operating range and resistance to
interference.
The Lectrosonics Digital Hybrid Wireless system overcomes channel noise in a dramatically new way, digitally
encoding the audio in the transmitter and decoding it
in the receiver, yet still sending the encoded information via an analog FM wireless link. This proprietary
algorithm is not a digital implementation of an analog
compandor but a technique which can be accomplished
only in the digital domain.
Since the RF link between transmitter and receiver is
FM, channel noise will increase gradually with increased operating range and weak signal conditions,
however, the Digital Hybrid Wireles system handles this
situation elegantly with rarely audible audio artifacts as
the receiver approaches its squelch threshold.
Rio Rancho, NM
In contrast, a purely digital system tends to drop the
audio suddenly during brief dropouts and weak signal
conditions. The Digital Hybrid Wireless system simply
encodes the signal to use a noisy channel as efficiently
and robustly as possible, yielding audio performance
that rivals that of purely digital systems, without the
power, noise and bandwidth problems inherent in digital
transmission. Because it uses an analog FM link, Digital
Hybrid Wireless enjoys all the benefits of conventional
FM wireless systems, such as excellent range, efficient
use of RF spectrum, and long battery life.
Servo Bias Input and Wiring
The input preamp is a unique design that delivers
audible improvements over conventional transmitter
inputs. Two different microphone wiring schemes are
available to simplify and standardize the configuration.
Simplified 2-wire and 3-wire configurations provide several arrangements designed for use only with servo bias
inputs to take full advantage of the preamp circuitry.
A line level input wiring provides an extended frequency
response with an LF roll-off at 35 Hz for use with instruments and line level signal sources.
DSP-controlled Input Limiter
The transmitter employs a digitally-controlled analog
audio limiter prior to the analog-to-digital converter.
The limiter has a range greater than 30 dB for excellent
overload protection. A dual release envelope makes the
limiter acoustically transparent while maintaining low
distortion. It can be thought of as two limiters in series,
connected as a fast attack and release limiter followed
by a slow attack and release limiter. The limiter recovers
quickly from brief transients, so that its action is hidden
from the listener, but recovers slowly from sustained
high levels to keep audio distortion low and preserve
short term dynamic changes in the audio.
Recorder function
The SMWB has a built in recording function for use in
situations where RF may not be possible or to work as
a stand alone recorder. The record function and transmit functions are exclusive of each other - you cannot
record AND transmit at the same time. The recorder
samples at 44.1kHz rate with a 24 bit sample depth.
(the rate was selected due to the required 44.1kHz rate
used for the digital hybrid algorithm). The micro SD card
also offers easy firmware update capabilities without
the need for a USB cable or driver issues.

Battery Status LED Indicator
AA batteries can be used to power the transmitter.
The LED labeled BATT on the keypad glows green
when the batteries are good. The color changes to red
when the battery voltage drops down and stays red
through most of the battery life. When the LED begins
to blink red, there will be only a few minutes remaining.
The exact point at which the LEDs turn red will vary
with battery brand and condition, temperature and
power consumption. The LEDs are intended to simply
catch your attention, not to be an exact indicator of
remaining time.
Some batteries give little or no warning when they
are depleted. If you wish to use these batteries in the
transmitter, you will need to manually keep track of the
operating time to prevent interruptions caused by dead
batteries.
Start with a fully charged battery, then measure the time
it takes for the Power LED to go out completely.
NOTE: The battery timer feature in many
Lectrosonics receivers is very helpful in measuring
battery runtime. Refer to the receiver instructions
for details on using the timer.
A weak battery will sometimes cause the LED to glow
green immediately after the transmitter is turned on, but
it will soon discharge to the point where the LED will
turn red or the unit will turn off completely.
LECTROSONICS, INC.
Digital Hybrid Wireless Belt-Pack Transmitters
Battery Installation
The transmitter is powered by two AA batteries. We
recommend using lithium for longest life.
Because some batteries run down quite abruptly, using
the Power LED to verify battery status will not be reliable. However, it is possible to track battery status using
the battery timer function available in Lectrosonics
Digital Hybrid Wireless receivers.
The battery door opens by simply unscrewing the
knurled knob part way until the door will rotate. The
door is also easily removed by unscrewing the knob
completely, which is helpful when cleaning the battery
contacts. The battery contacts can be cleaned with
alcohol and a cotton swab, or a clean pencil eraser. Be
sure not to leave any remnants of the cotton swab or
eraser crumbs inside the compartment.
A small pinpoint dab of silver conductive grease* on the
thumbscrew threads can improve battery performance
and operation. Do this if you experience a drop in battery life or an increase in operating temperature.
Insert the batteries according to the markings on the
back of the housing. If the batteries are inserted incorrectly, the door may close but the unit will not operate.
*if you are unable to locate a supplier of this type of
grease - a local electronics shop for example - contact
the factory for a small maintenance vial.

Microphones, line level audio sources and instruments
can be used with the transmitter. Refer to the section
entitled Input Jack Wiring for Different Sources for
details on the correct wiring for line level sources and
microphones to take full advantage of the Servo Bias
circuitry.
Using Line Level and Instrument Inputs
Line level signals can be sent to the input with the
proper wiring. Refer to the section on Input Jack Wiring for Different Sources for details.
Helpful Features on Receivers
To aid in finding clear frequencies, several Lectrosonics
receivers offer a SmartTune feature that scans the tuning range of the receiver and displays a graphical report
that shows where RF signals are present at different
levels, and areas where there is little or no RF energy
present. The software then automatically selects the
best channel for operation.
Lectrosonics receivers equipped with an IR Sync function allow the receiver to set frequency, step size and
compatibility modes on the transmitter via an infrared
link between the two units.
Audio level
When the frequency step size is set to 25 kHz, the hex
number will appear smaller and may include a fraction.

When two frequency bands overlap, it is possible to
select the same frequency at the upper end of one and
the lower end of the other. While the frequency will be
the same, the pilot tones will be different, as indicated
by the hex codes that appear.
In the following examples, the frequency is set to
494.500 MHz, but one is in band 470 and the other in
band 19. This is done intentionally to maintain compatibility with receivers that tune across a single band. The
band number and hex code must match the receiver to
enable the correct pilot tone.

Digital Hybrid Wireless Belt-Pack Transmitters
Microphone RF Bypassing
Line Level Signals
When used on a wireless transmitter, the microphone
element is in the proximity of the RF coming from the
transmitter. The nature of electret microphones makes
them sensitive to RF, which can cause problems with
microphone/transmitter compatibility. If the electret
microphone is not designed properly for use with wireless transmitters, it may be necessary to install a chip
capacitor in the mic capsule or connector to block the
RF from entering the electret capsule.
Some mics require RF protection to keep the radio signal from affecting the capsule, even though the transmitter input circuitry is already RF bypassed.
If the mic is wired as directed, and you are having difficulty with squealing, high noise, or poor frequency
response, RF is likely to be the cause.
The best RF protection is accomplished by installing RF
bypass capacitors at the mic capsule. If this is not possible, or if you are still having problems, capacitors can
be installed on the mic pins inside the TA5F connector housing. Refer to the diagram below for the correct
locations of capacitors.
Use 330 pF capacitors. Capacitors are available from
Lectrosonics. Please specify the part number for the
desired lead style.
The wiring for line level and instrument signals is:
• Signal Hot to pin 5
• Signal Gnd to pin 1
• Pin 4 jumped to pin 1
This allows signal levels up to 3V RMS to be applied
without limiting.
NOTE for line level inputs only (not instrument):
If more headroom is needed, insert a 20 k resistor
in series with pin 5. Put this resistor inside the
TA5F connector to minimize noise pickup. The
resistor will have little or no effect on the signal if
the input is set for instrument.

Firmware Update
Firmware updates are made using a microSDHC
memory card. Download and copy the following firmware update files to a drive on your computer.
• smwb vX_xx.ldr is the firmware update file, where
“X_xx” is the revision number.
In the computer:
1) Perform a Quick Format of the card. On a Windows-based system, this will automatically format
the card to the FAT32 format, which is the Windows
standard. On a Mac, you may be given several
options. If the card is already formatted in Windows (FAT32) - it will be greyed out - then you do
not need to do anything. If the card is in another
format, choose Windows (FAT32) and then click
“Erase”. When the quick format on the computer is
complete, close the dialogue box and open the file
browser.
2) Copy the smwb vX_xx.ldr file to the memory card,
then safely eject the card from the computer.
In the SMWB:
1) Leave the SMWB turned off and insert the microSDHC memory card into the slot.
2) Hold down both the UP and DOWN arrow buttons
on the recorder and turn the power on.
7) If you re-insert the update card and turn the power
back on for normal use, the LCD will display a message prompting you to format the card:
Format Card?
(files lost)
• No
• Yes
If you wish to record audio on the card, you must
re-format it. Select Yes and press MENU/SEL to
format the card. When the process is complete, the
LCD will return to the Main Window and be ready
for normal operation.
If you choose to keep the card as is, you may remove the card at this time.
The firmware update process is managed by a bootloader program - on very rare occasion, you might need
to update the bootloader.
• smwbboot vX_xx.ldr is the bootloader file
Follow the same process as with a firmware update and
select the smwbboot file. Be forewarned, this can corrupt your unit if interrupted. Don’t update the bootloader
unless advised to do so by the factory (not for the faint
of heart).
3) The recorder will boot up into the firmware update
mode with the following options on the LCD:
• Update - Displays a scrollable list of the .ldr files
on the card.
• Power Off - Exits the update mode and turns the
power off.
NOTE: If the unit screen shows FORMAT CARD?,
power the unit off and repeat step 3. You were not
properly pressing UP, DOWN and Power at the
same time.
4) Use the arrow buttons to select Update. Use the
UP and DOWN arrow buttons to select the desired
file and press MENU/SEL to install the firmware.
The LCD will display status messages while the
firmware is being updated.
5) When the update is complete, the LCD will display
this message: UPDATE SUCCESSFUL REMOVE
CARD. After the card is removed, the LCD will
return to the three options shown in step 4 above.
6) Select Power Off and press MENU/SEL to finish
the update.

Recovery Process
In the event of a battery failure while the unit is recording, a recovery process is available to restore
the recording in proper format. When a new battery is
installed and the unit is turned back on, the recorder
will detect the missing data and prompt you to run the
recovery process. The file must be recovered or the
card will not be usable in the SMWB.
First it will read:
Interrupted Recording
Found
The LCD message will ask:
Recover?
for safe use
see manual
You will have the choice of No or Yes (No is selected
as the default). If you wish to recover the file, use the
DOWN arrow button to select Yes, then press MENU/
SEL.
The next window will give you the option to recover all
or part of the file. The default times shown are the best
guess by the processor where the file stopped recording. The hours will be highlighted and you can either
accept the value shown or select a longer or shorter
time. If you are unsure, simply accept the value shown
as the default.
Press MENU/SEL and the minutes are then highlighted.
You can increase or decrease the time to be recovered.
In most cases you can simply accept the values shown
and the file will be recovered. After you have made your
time choices, press MENU/SEL again. A small GO!
symbol will appear next to the DOWN arrow button.
Pressing the button will initiate the file recovery. The
recovery will happen quickly and you will see:
Recovery
Successful
Special Note:
Files under 4 minutes long may recover with additional
data “tacked on” to the end of the file (from previous
recordings or data if the card had been used previously). This can be effectively eliminated in post with a
simple delete of the unwanted extra “noise” at the end
of the clip. The minimum recovered length will be one
minute. For example, if the recording is only 20 seconds
long, and you have selected one minute there will be
the desired 20 recorded seconds with an additional 40
seconds of other data and or artifacts in the file. If you
are uncertain about the length of the recording you can
save a longer file - there will simply be more “junk” at
the end of the clip. This “junk” may include audio data
recorded in earlier sessions that were discarded. This
“extra” information can be easily deleted in post production editing software at a later time.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment
needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting
cables and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection,
send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once set at the
factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are
no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest
flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does
to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone
for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by email or by phone. We need
to know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly shown
on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed” for
safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
