Introduction
The SMB Series transmitters are the product of many
years of engineering and experience in professional
audio markets. The unique design provides several
distinct features for professional applications:
• Superb,compandor-freeaudioquality
• Ultra-lightweight,corrosionresistanthousing
• Waterresistantsealsforuseindampenviron-
ments
• Programmablecompatibilitymodesforusewitha
wide variety of different receivers
The Digital Hybrid Wireless® design (US Patent
7,225,135) combines 24-bit digital audio with analog
FM resulting in a system that has the same operating
range as analog systems, the same spectral efficiency as analog systems, the same long battery life
as analog systems, plus the excellent audio fidelity
typical of pure digital systems.
The transmitters feature the unique servo bias input
circuitry with a standard TA5M type input jack for use
with electret lavaliere mics, dynamic mics, or line level
signals. A water resistant control panel with LCD,
membrane switches and multi-color LEDs make input
gain adjustments, frequency and compatibility mode
selection quick and accurate, without having to view
the receiver. The battery compartment accepts AA
lithium or rechargeable batteries. The housings are
machined from solid aluminum blocks to provide an
extremely lightweight and rugged package. A special
non-corrosive finish resists salt water exposure and
perspiration in extreme environments.
The DSP-based design works with Euro version Digital Hybrid and IFB receivers.

Servo Bias Input
The voltage and current requirements of the wide
variety of electret microphones used in professional
applications has caused confusion and compromises
in the wiring needed for wireless transmitters. To address this problem, the unique Servo Bias input circuit
provides an automatically regulated voltage over a
very wide range of current for compatibility with all
microphones.
Digital Hybrid Wireless® Technology
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
(typically “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 and resistance to interference.
Digital Hybrid systems overcome 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 that can be accomplished only in the digital
domain, even though the inputs and outputs are
analog.
Because it uses an analog FM link, the Digital Hybrid
system enjoys all the benefits of conventional FM
wireless systems and it does away with the analog
compandor and its artifacts.
General Technical Description
No Pre-Emphasis/De-Emphasis
The Digital Hybrid design results in a signal-to-noise
ratio high enough to preclude the need for conventional
pre-emphasis (HF boost) in the transmitter and deemphasis (HF roll off) in the receiver. This eliminates
the potential for distortion of signals with abundant
high-frequency information.
Low Frequency Roll-Off
The low frequency roll-off can be set for a 3 dB down
point at 35, 50, 70, 100, 120 and 150 Hz to control
subsonic and very low frequency audio content in
the audio. The actual roll-off frequency will vary slightly
depending upon the low frequency response of the
microphone.
Excessive low frequency content can drive the transmitter into limiting, or in the case of high level sound
systems, can even cause damage to loudspeaker
systems. The roll-off is normally adjusted by ear
while listening as the system is operating.
Input Limiter
A DSP-controlled analog audio limiter is employed
before the A-D converter. The limiter has a range of
more 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, a fast attack and
release limiter followed by a slow attack and release
limiter. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio
distortion low while preserving short term dynamics.

Signal Encoding and Pilot Tone
In addition to controlling the limiter, the DSP also encodes the digitized audio from the A/D converter and
adds an ultrasonic pilot tone to control the squelch
in the receiver. A pilot tone squelch system provides a
reliable method of keeping a receiver output muted
when the squelch is active, even in the presence of
significant interference. When the system is operating
in the hybrid mode, a different pilot tone frequency
is generated for each carrier frequency to prevent
squelch problems in multi-channel systems.
Microprocessor Control
A microprocessor monitors user command inputs
from the control panel buttons and numerous other
internal signals. It works intimately with the DSP to
ensure the audio is encoded according to the selected Compatibility Mode and that the correct pilot tone
is added to the encoded signal.
Compatibility Modes
SMB transmitters are designed to operate with Lectrosonics Digital Hybrid receivers and will yield the
best performance when doing so, however, due to the
flexibility of digital signal processing, they can also
operate with Lectrosonics Euro version IFB receivers.
Control Panel
The control panel includes four membrane switches and
an LCD screen to adjust the operational settings. Multicolor LEDs are used to indicate audio signal levels for
accurate gain adjustment and for battery status.
Battery Options and Operating Time
Switching power supplies convert regulated battery
voltages to operate various circuit stages with maximum efficiency. With the variety of alkaline, lithium
and rechargeable NiMH batteries available today in
the AA format, there are many choices to maximize
operating time or minimize cost as needed for any
application.
The firmware “remembers” the power status when a
battery fails or power is disconnected, so the transmitter will be turned on automatically when power is
restored and previous settings will be enabled.
Frequency Blocks
Lectrosonics established a “block” numbering system
years ago to organize the range of frequencies that
are available. Legacy transmitters and receivers used
two binary switches, each with 16 positions, to set the
operating frequency. 16 x 16 = 256, which defined the
standard number of frequencies in each block to be
256. Since the steps between frequencies is 100 kHz,
this results in a switching range of 25.6 MHz.
The lowest frequency in the switching range divided by 25.6 yields the block number. For example,
640.000 divided by 25.6 equals 25. In other words,
block 25 starts at 640.000 MHz.
To determine what block a particular frequency falls
into, divide the frequency and use the two significant
digits to the left of the decimal. For example, to calculate the block for 580.500 MHz, divide 580 by 25.6,
which equals 22.656, which indicates block 22.
Circulator/Isolator
The RF output circuit includes a one way circulator/
isolator using a magnetically polarized ferrite. This
device greatly reduces RF intermodulation produced
when multiple transmitters are used in close proximity
to one another (a meter or two, or less). The isolator
also protects the output amplifier against static shock.

Controls and Functions
LCD Screen
The LCD is a numeric-type Liquid Crystal Display with
screens for adjusting power, frequency, audio level
and low frequency audio roll-off. The transmitter can
be powered up with or without the RF output turned
on. A countdown appears in the LCD when powering
on and off, allowing the transmitter to be turned on
without RF for adjustments, and to prevent accidentally turning it off with momentary button presses.
Power LED
The PWR LED glows green when the battery is good.
The color changes to red at a mid-point of operating
life, and will continue to glow red until the battery gets
close to the end of its life. When the LED begins to
blink red, there are only a few minutes remaining.
The exact point at which the LED turns red will vary
with battery brand and condition, temperature and
current drain. The LED is simply a reminder intended
to catch your attention, not an exact indicator of remaining time.

Green Red Blink
Example of AA lithium battery in SMB transmitter
A NiMH rechargeable battery will give little or no
warning when it is depleted because the voltage does
not vary much during its operating life. If you wish
to use NiMH batteries, we recommend trying fully
charged batteries in the unit and using the battery
timer feature available in most receivers to determine
the available operating time.
A weak battery will sometimes cause the PWR LED
to glow green immediately after the transmitter is
turned on, but the battery will soon discharge to the
point where the LED will turn red or the unit will turn
off completely. When the transmitter is in SLEEP
mode, the LED blinks green every few seconds.
Audio Input Jack
The Servo Bias input circuitry accommodates virtually every lavaliere, handheld or shotgun microphone
available, plus line level signals.
Modulation LEDs
Proper input gain adjustment is critical to ensure the
best audio quality. Two bicolor LEDs will glow either
red or green to accurately indicate modulation levels.
The input circuitry includes a wide range DSP controlled limiter to prevent distortion at high input levels.
It is important to set the gain (audio level) high
enough to achieve full modulation during louder peaks
in the audio. The limiter can handle over 30 dB of level
above full modulation, so with an optimum setting,
the LEDs will flash red during use. If the LEDs never
flash red, the gain is too low. In the table below, +0 dB
indicates full modulation.

AUDIO Button
The AUDIO button is used to display the audio level
and low frequency roll-off settings. The UP and
DOWN arrows adjust the values.
The AUDIO button is also used with the FREQ button to
enter standby mode and to turn the transmitter on or off.
FREQ Button
The FREQ Button displays the selected operating frequency and also toggles the LCD between displaying
the actual operating frequency in MHz and a two-digit
hexadecimal number that corresponds to the equivalent Lectrosonics Frequency Switch Setting.
The FREQ button is also used with the AUDIO button to
enter standby mode and to turn the transmitter on or off.
Up/Down Arrows
The Up and Down arrow buttons are used to select
the values on the various setup screens and to lock
out the control panel. Pressing both arrows simultaneously enters the lock countdown. When an attempt is
made to change a setting while the control panel is
locked, a message will flash on the LCD reminding
you that the unit is locked. Once locked, the buttons
can only be unlocked by removing the battery, or via
the RM remote control (if the remote function was
enabled in the transmitter setup).
Antenna
The transmitter uses a whip antenna with a flexible
woven, galvanized steel mesh cable and a standard
SMA connector.

Setup Screens
Audio Screen
The Audio screen is used
to adjust input gain from 0
to +44 dB, and the low
frequency roll-off from 35
to 150 Hz. Repeatedly
pressing the AUDIO
button toggles back and
forth between the two
displays. Press and hold the AUDIO button and use
the Up and Down arrows to make adjustments.
Frequency Screen
The Frequency Screen
displays the operating
frequency in MHz or as a
two-digit hexadecimal
number that corresponds
to the equivalent Lectro-
sonics Frequency Switch
Setting. Repeatedly
pressing the FREQ button toggles between the two
displays. Press and hold the FREQ button and use
the Up and Down arrows to select the frequency.
Lock/Unlock Screen
Simultaneously pressing
and holding both the Up
and Down arrow buttons
during normal operation
starts the Lock timer. The
timer starts at three and
counts down to zero.
When the timer reaches zero, the transmitter’s
controls are locked.
With the controls locked, the AUDIO and FREQ buttons can still be used to display current settings. Any
attempt to change a setting by pressing either the Up
or Down arrow button will result in an on-screen Loc
reminder that the controls are locked. Remove the
batteries to unlock the control panel.
Important: Once the transmitter is locked, it
cannot be unlocked or powered off using the
buttons. The only ways to unlock a locked
transmitter are to remove the battery or unlock
it using the RM remote control if this function is
enabled on the transmitter.
Remote Control Operation
Remote Control Screens
The transmitters can be
configured to respond to
signals from the RM
remote control unit or to
ignore them. This setting
is accessed by holding
down the Down arrow
button while powering the
transmitter on.
If a remote control signal is detected but the transmitter is set to rc oFF, the message rc oFF will be
displayed briefly on the transmitter’s LCD, to confirm
that a valid signal was received, but that the transmitter is not configured to respond to it.
Functions available from the remote control are:
• AudioLevel
• Frequency
• Lock/UnlockButtons
• Sleep/Wake(powersavingmode)
In sleep mode, the transmitter uses only 20% of the
normal amount of battery drain. Sleep mode can only
be invoked with the remote control, and can only be
revoked with the remote control or by removing the
battery. When in the sleep mode, the PWR LED blinks
green every few seconds to indicate that the transmitter
is asleep and not turned off.
The RM is not included with SM Series transmitters.
Several “Dweedle tones” can also be downloaded
from the web site at:
http://www.lectrosonics.com/europe/en/Transmitters/
rm.html
The dweedle tones can be played back through an
MP3 player, PDA, smart phone, etc., and in most
cases, will even work with walkie talkies. The tones
will not work through the loudspeakers of a sound
system because the reflections and reverberation in
the room will alter the tones.
Configuring for Power Restore
Power Restore Screens
The Power Restore feature
will turn the transmitter
back on with the same
settings that were enabled
in the previous use after a
battery is replaced or
external power has been
cycled off and back on.
1) Press and hold the Down Arrow Button then
power on the transmitter by pressing the
Audio and Freq buttons simultaneously.
2) Press AUDIO or FREQ key to scroll to the setting

Microphone RF Bypassing
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
the 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 (see
schematic diagram).
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.
Install the capacitors as follows: Use 330 pF capacitors. Capacitors are available from Lectrosonics.
Please specify the part number for the desired lead
style.
Leaded capacitors: P/N 15117
Leadless capacitors: P/N SCC330P
All Lectrosonics lavaliere mics are already bypassed
and do not need any additional capacitors installed for
proper operation.
Line Level Signals
The normal hookup for line level signals is:
• SignalHottopin5
• SignalGndtopin1
• Pin4jumpedtopin1
This allows signal levels up to 3V RMS to be applied
without limiting.
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.

Optional RM/E Remote Control
The RM/E unit gives you remote control of SM Series
transmitters using an audible tone delivered to the microphone. The panel layout is the same as the transmitters. Simply set the desired value or mode on the
LCD, then press the send button to set the transmitter
to the same setting or mode.
Hold the speaker on the RM/E close to the microphone when pressing the pushbutton. A “dweedle”
tone will play from the RM/E speaker into the microphone and the parameter on the transmitter will be
set immediately.
Available adjustments:
• Audioinputgain
• Frequency
• LockorUnlockModes
• SleepModeON/OFF
Send Button
Speaker
When the transmitter is in the power saving sleep
mode, it uses only 20% of the normal battery drain,
so battery life with be 5 times longer. This is especially
useful in situations where the transmitter is buried
deep inside costuming and there are waiting periods
between use. The transmitter can “sleep” for several
hours and then be awakened and adjusted when the
production is about to begin.
Powering the RM on and off
To turn the RM/E on or off, press the AUDIO and
FREQ buttons together briefly. The unit powers up on
the page that was displayed when the unit was powered off last.
The setup screens are accessed with the AUDIO and
FREQ buttons. Once on the desired screen, the value
is adjusted with the UP and DOWN arrow buttons.
To change a transmitter’s setting via the RM/E, select
the screen and value, then press the SEND button
while holding the speaker close to the microphone.
The speaker should be uncovered and held within a
few inches of the transmitter’s microphone. The longest usable range is about 6 feet, depending on the
microphone and volume settings used.
Only the specific function displayed is altered. For
example, if the remote control is on the Aud (audio
level/gain) screen, pressing the send button will set
the gain on the transmitter but will not affect any other
setting.
Setup Screens
The AUDIO button cycles through 4 screens:
1) Aud - set transmitter’s audio level
2) SLEEP/unSLP - cause transmitter to sleep or wake
up
3) Loc/unLoc - lock or unlock transmitter’s buttons
4) Loud - adjust RM/E speaker volume
(press SEND button for a sa mple tone)
5) Pr - Transmit outpit power (only in SM & SMVs)
The FREQ button cycles through 2 or 3 screens,
depending on the settings:
1) CH - set transmitter’s channel
(using block-independent hex code)
2) b - select a block number
(optional — uncovers next page)
3) 000.000 - set transmitter’s frequency in MHz
(avail. if a block is selected)
A single AA Lithium battery will operate
the RM/E for up to several years.
Unscrew the knurled knob for access to
the battery compartment.

Operating Notes
• Thesensitivitytothe
remote control varies with
the transmitter’s audio
level setting and the
microphone used, but it is
always possible to make
it work with a sufficiently
loud remote signal at
close range.
• Ifthetransmitterisconfigured to respond to the
remote control, it will do
so even if the buttons are
locked.
• Whenthetransmitteris
asleep, it can only be
awakened by the remote
control, or by removing
and reinserting the battery.
• Whenthetransmitterisasleep,thePWRled
blinks green every few seconds.
• Ifaremotecommandissentthatwouldresultin
the same display being shown again on the transmitter (for example tuning to the channel already
displayed), a row of dashes is displayed briefly,
as a signal that the command was received, but it
didn’t change anything.
• Ifyouarehavingtroublegettingthetransmitter to respond, make sure you aren’t covering
the speaker w ith your thumb, and/or turn up the
speaker volume on the Loud page.
• IftheRM/Eissettoadifferentblocknumberthan
the transmitter and an attempt is made to set the
transmitter’s frequency in MHz, the command
will still work. The transmitter is simply set to the
corresponding channel in the correct block, with a
matching hexadecimal number.
• TheaudiosignalfromtheRM/Ewillchangethe
settings of all transmitters within range. Experiment with this to prevent accidental changes to
another transmitter during a production.

SYMPTOM POSSIBLE CAUSE
HISS AND NOISE -- AUDIBLE DROPOUTS 1) Transmitter gain (audio level) far too low.
2) Receiver antenna missing or obstructed.
3) Transmitter antenna broken or missing.
4) Operating range too great.
5) Signal interference. Turn off transmitter. If receiver’s signal
strength indicator does not drop to nearly zero, this indicates
an interfering signal may be the problem.
Try a different operating frequency.
“Loc” APPEARS IN DISPLAY WHEN ANY BUTTON IS PRESSED
1) Control Panel is locked. (See Operating Instructions, Locking
and Unlocking the Control Panel.)
“Hold” APPEARS IN DISPLAY WHEN ARROW BUTTONS ARE PRESSED
1) Reminder that it is necessary to hold down the AUDIO or
FREQ button to make adjustments to the audio gain or
frequency settings.
“PLL” APPEARS IN DISPLAY 1) Indication that the PLL is not locked. This is a serious condition
that requires factory repair. It may be possible to operate on
another frequency far removed from the one that was selected
when the condition was indicated.
TRANSMITTER WON’T RESPOND TO REMOTE CONTROL
1) If LCD blinks “rc oFF”, transmitter has not been configured
to respond to the remote control. See “Remote Control
Operation” on page 16 for instructions on how to configure.
2) If LCD blinks “- - - - - -”, transmitter is already set as
requested by the remote control.
3) If transmitter does not respond at all, try moving the remote
control closer to the microphone or increasing the remote
control’s loudness setting, or increasing the audio level on the
transmitter.
4) Make sure volume of RM and proximity of microphone are
sufficient to engage transmitter.
5) Make sure transmitter is not in Sleep mode.
RM Troubleshooting
FREQUENCY CHANGES, BUT NOT TO DESIRED FREQUENCY
1) RM set on different block than transmitter in question. RM uses
hex code to set frequency - set RM to proper frequency block,
or use hex code method to change frequency.

Adjusting Audio Level (Gain)
The control panel Modulation LEDs indicate the audio
level and limiter activity. Once set, the transmitter’s
audio level setting should not be used to control the
volume of your sound system or recorder levels. This
gain adjustment matches the transmitter gain with the
microphone’s output level, the user’s voice level and
the position of the microphone. The audio input level
(gain) is adjusted with the unit in the Standby Mode or
while powered up while observing the LEDs.
It is desirable to to set the gain so that some limiting
occurs on louder peaks. The limiter is very transparent
and its effect is not audible until the system is close to
overload. In other words, don’t be shy about turning
up the gain. In fact, it is a good idea to turn the gain
up to maximum and listen for distortion or compression to get a feel for how much headroom the system
actually has.
Signal Level -20 LED -10 LED
Less than -20 dB
Off Off
-20 dB to -10 dB
Green Off
-10 dB to +0 dB Green Green
+0 dB to +10 dB Red Green
Greater than +10 db
Red Red
Note: Different voices will usually require
different gain settings, so check this adjustment
as each new person uses the system. If several
different people will be using the transmitter
and there is not time to make the adjustment for
each individual, adjust it for the loudest voice.
1) With the transmitter powered off, plug in the microphone and make sure the connector is firmly
seated.
Warning: If the systems is powered up while
connected to a live sound system, be careful
to turn the sound system level down first or
severe feedback can occur.
2) Place the transmitter in Standby Mode or turn it
on for normal use.
3) Position the microphone in the location where it
will be used in actual operation.
4) Observe the Modulation LEDs while speaking or
singing into the microphone at the same voice
level that will be used during use. While holding
the AUDIO button, press the UP or DOWN arrow
buttons until the both the -20 and -10 LEDs glow
green, with the -20 LED occasionally flickering
red. This will maximize the signal to noise ratio of
the system with full modulation and provide subtle
limiting to prevent overload and audible compression.
5) If the unit was set up in Standby Mode, it will be
necessary to turn the transmitter off, then power it
up again in normal operation so the RF output will
be on. Then the other components in the sound or
recording system can be adjusted.
Locking or Unlocking the Controls
Control Panel Locked
The Lock mode protects
the transmitter from
accidental changes to its
settings.
Simultaneously press both
the Up and Down arrow buttons to start the countdown timer. When the timer reaches zero, “Loc” is
displayed and the controls are locked. Settings can be
reviewed but not changed.
Once the transmitter is locked, it cannot be unlocked or
powered off using the buttons. The only ways to unlock
a locked transmitter are to remove the battery or unlock
it using the remote control. The remote control will work
only if the transmitter was previously configured to
respond to the remote control. The unit will always
power up in “unlocked” mode.
Attaching and Removing the Microphone
The flexible sleeve over the 5-pin plug on the microphone helps prevent dust and moisture from getting
into the input jack. A flange is machined into the rim
of the connector on the transmitter to help retain the
sleeve after it is installed.
The following procedure simplifies the attachment and
removal of the microphone to assure the sleeve is
seated securely.
Align the pins on the plug and jack and insert the connector.
1
If the sleeve is pulled down
and covering the connector, squeeze the end of the
sleeve so you can feel the
connector inside and press it
into the jack until it latches.
Pinch and
squeeze the
sleeve on this end
to work it down
over the flange.
2
Pinch and squeeze the
sleeve near the flange and
work it down with a kneading
motion over the flange all the
way around until it stays in
place flush with the housing.
Pull on the connector to
make sure it is firmly latched.
3
Release button
To remove the connector,
pull the sleeve back to
expose the black release
button. Press the button to
unlatch the plug.

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.
