Introduction
The SM Series variable power 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:
Selectable output power to maximize battery life or
operating range as needed
Superb, compandor-free audio quality
Ultra-lightweight, corrosion resistant housing
Water resistant seals for use in damp environments
Programmable compatibility modes for use with a
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 SM Series 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 billets to provide an
extremely lightweight and rugged package. A special
non-corrosive finish resists salt water exposure and
perspiration in extreme environments.

Servo Bias Input
The voltage and current requirements of the wide vari-
ety of electret microphones used in professional appli-
cations 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 de-
gree, and all wireless microphone systems seek to mini-
mize the impact of that noise on the desired signal. Con-
ventional 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 send-
ing the encoded information via an analog FM wireless
link. This proprietary algorithm is not a digital imple-
mentation 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 wire-
less systems and it does away with the analog compan-
dor 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 de-emphasis
(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 sub-
sonic and very low frequency audio content in the au-
dio. The actual roll-off frequency will vary slightly depend-
ing upon the low frequency response of the microphone.
Excessive low frequency content can drive the transmit-
ter into limiting, or in the case of high level sound sys-
tems, 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 be-
fore the A-D converter. The limiter has a range of more
than 30 dB for excellent overload protection. A dual re-
lease envelope makes the limiter acoustically transpar-
ent 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.

Rio Rancho, NM 5
Signal Encoding and Pilot Tone
In addition to controlling the limiter, the DSP also en-
codes 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 reli-
able method of keeping a receiver output muted (audio
mute) even in the presence of significant interference.
When the system is operating in the hybrid mode, a dif-
ferent pilot tone frequency is generated for each carrier
frequency to prevent inadvertent squelch problems in
multi-channel sytems.
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 Compatibil-
ity Mode and that the correct pilot tone is added to the
encoded signal.
Compatibility Modes
SM transmitters are designed to operate with Lectroson-
ics Digital Hybrid receivers and will yield the best per-
formance when doing so, however, due to the flexibility
of digital signal processing, the transmitter can also
operate with Lectrosonics IFB receivers in the same
frequency band.
Control Panel
The control panel includes four membrane switches and
an LCD screen to adjust the operational settings. Multi-
color LEDs are used to indicate audio signal levels for
accurate gain adjustment and for battery status.
Variable Power Output
This advanced feature allows the operator to optimize
the transmitter for maximum battery life, or for slightly
increased operating range. Power output is selected us-
ing the LCD in a setup mode while the RF output of the
transmitter is turned off.
Battery Options and Operating Time
Switching power supplies convert regulated battery volt-
ages to operate various circuit stages with maximum
efficiency.
The firmware “remembers” the power status when a
battery fails, so the transmitter will be turned on auto-
matically when the battery is replaced and the previous
settings will be enabled.
Circulator/Isolator
The RF output circuit includes a one way circulator/iso-
lator using a magnetically polarized ferrite. This device
greatly reduces RF intermodulation produced when
multiple transmitters are used in close proximity to one
another (several feet apart). The isolator also provides
additional RF output stage protection 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 midpoint of the runtime
as the battery voltage drops. When the LED begins to
blink red, there is usually less than 30 minutes remain-
ing with a lithium battery.
The exact point at which the LED turns red will vary with
battery brand and condition, temperature, and the out-
put power setting. The LED is intended to simply catch
your attention, not to be an exact indicator of remaining
time. The illustration below depicts typical behavior with
a lithium battery in the single battery model at 50 mW.

Green Red Blink
A weak battery will sometimes cause the PWR LED to
glow green immediately after the transmitter is turned
on, but will soon discharge to the point where the LED
will turn red or the unit will turn off completely.
Power LED Off Feature
In normal operating mode, the UP and DOWN arrow
buttons may be used to turn the PWR LED indica-
tors off and on. This setting does not persist through a
power cycle nor does it affect the LCD backlight.
Audio Input Jack
The Servo Bias input circuitry accommodates virtually
every lavaliere, handheld or shotgun microphone avail-
able, plus line level signals.
Battery Compartment and Thumb Screw
The large knurled thumbscrew is used to release or
secure the Battery Compartment Cover Plate.
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 (-20 LED just turns red).
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
AUDIO and FREQ Buttons
The AUDIO button is used to display the audio level and
low frequency roll-off settings. The UP and DOWN ar-
row buttons adjust the values.
The FREQ Button displays the selected operating
frequency and toggles the LCD between displaying
the actual operating frequency in MHz and a two-digit
hexadecimal number that corresponds to the equivalent
frequency switch setting on legacy transmitters.
Pressing both buttons simultaneously enters the
standby mode and turns the unit on and off
UP/DOWN Arrow Buttons
The UP and DOWN arrow buttons are used to select
the values on the various setup screens and to lock out
the control panel.
Antenna
The transmitter uses a whip antenna with a flexible wo-
ven, galvanized steel mesh cable and a standard SMA
connector.

Attaching and Removing
the Microphone
The flexible sleeve over the 5-pin plug on the micro-
phone helps prevent dust and moisture from getting into
the input jack, and provides additional strain relief. The
flange around the rim of the connector on the transmitter
creates a splash proof connection and keeps the sleeve
securely attached.
The following procedure simplifies the attachment and
removal of the microphone to assure the sleeve is
seated securely.
Align the latch on the plug and jack and insert the
connector. It is easier to attach the microphone when
the sleeve is pulled back as shown in the Step 3 photo
below.
1If 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.

return to the previous state after a battery change or
power interruption when it is in the operating mode.
This is convenient when the transmitter is powered by
an external source.
1 Restores power automatically
0 Does not restore power automatically
AUDIO Button
When the unit is turned on in either the Standby or
Operating Mode, pressing the AUDIO button repeatedly
switches between the available settings.
LF (XX) adjusts the low frequency roll-off of the
audio signal.
AUD (XX) adjusts the input gain
LF (XX) - Adjusting the Low Frequency Roll-off
Repeatedly press the AUDIO button until the LF roll-
off adjustment screen appears. Then press and hold
the AUDIO button while selecting the desired roll-off
frequency with the UP and DOWN arrows.
The roll-off frequency can be set to 35, 50, 70, 100, 120
and 150 Hz.
AUD (XX) - Adjusting Audio Level (Gain)
The control panel modulation LEDs marked -10 and -20
indicate the audio level and limiter activity. Once adjust-
ed according to the following procedure, the transmit-
ter’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) should be adjusted with the unit in the Standby
Mode while observing the LEDs.
It is generally best to set the LF roll-off before adjust-
ing the gain, since low frequency energy can affect the
input level to the transmitter.
It is desirable to to set the gain so that some limiting
occurs on louder peaks. The limiter is very transparent
over a 43 dB range, 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.
It is actually a good idea to turn the gain up to maxi-
mum and listen for distortion or compression to get a
feel for how much headroom is available.
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: If several different people will be using the transmitter
and there is not time to make the adjustment for each indi-
vidual, adjust it for the loudest voice.
1) With the transmitter in the Standby Mode, plug in
the microphone and make sure the connector is
firmly seated.
Warning: If the wireless system 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) Position the microphone in the location where it will
be used in actual operation.
3) Observe the modulation LEDs while speaking or
singing into the microphone at the same voice level
that will be used during operation. 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 flickering red during louder
peaks in the audio. This will maximize the signal to
noise ratio of the system with full modulation.
4) 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.

FREQ Button
The operating frequency can be adjusted according to
the frequency in MHz or a two-digit hexadecimal code.
Press the button repeatedly to switch between the two
displays. The display switches when the button is first
pushed; push and hold the button in the desired mode
and use the UP and DOWN arrow buttons to make the
adjustment.
In this example, the same frequency is displayed in
MHz and the equivalent hex code.
The hex code is a hexadecimal sequence that pro-
gresses upward from lowest to highest frequency using
the numerals and letters from 0 through F. When the
frequency is on a 100 kHz step, the hex code is only
two digits, as shown above, which is easy to remember.
When the step size is set to 25 kHz, additional charac-
ters are used to denote the exact frequency with four
characters.
Locking/Unlocking the Control Panel
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 buttons on the control
panel 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
via the RM remote control.
Remote Control Operation
Remote Control Screens
The transmitter can be
controlled by signals from
audio “dweedle” tones
generated by a mobile phone,
or with the Lectrosonics RM
and RM2 devices.
The remote function is enabled in the UP arrow power
on options (see previous section). If a remote control
signal is detected but the function is no enabled, the
message rc oFF will be displayed briefly on the trans-
mitter’s LCD.
Remote functions available are:
Tx Input Gain
• Sleep/Unsleep
• Lock/Unlock
• Frequency

Input gain functions
In sleep mode, the transmitter uses about 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.

2) Slide Rubber Boot onto microphone cable with the
large end facing away from the microphone. (See illus-
tration above.)
3) If necessary, slide the 1/8-inch black shrink tubing
onto the mircrophone cable. (This tubing is needed
for some cables to ensure the cable fits snugly in the
rubber boot.)
4) Use the resistors and connector included with this kit
to configure the TA5F to your particular microphone.
(See Wiring Diagrams below.) A length of .065 OD
clear tubing is included if insulating the resistor leads
or shield wire is necessary. (Remove rubber strain
relief from connector backshell by pulling it out of the
backshell.)
5) Slide the Strain Relief over the TA5F Insert and
crimp as shown to the right. Then insert the TA5F
Insert and Strain Relief in the TA5F Latchlock. Screw
the TA5F Flex Relief onto the TA5F Latchlock.
6) If needed, position and shrink the 1/8-inch shrink tub-
ing on the microphone cable, then slide the Rubber
Boot down over the TA5F connector.
Line Level Signals
The normal hookup for line level signals is: Signal Hot
to pin 5, Signal Gnd to pin 1 and pin 4 jumped to pin 1.
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 con-
nector to minimize noise pickup.

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 wire-
less 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 dif-
ficulty 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 pos-
sible, or if you are still having problems, capacitors can
be installed on the mic pins inside the TA5F connector
housing.

Silver Paste on SM Series
Transmitter Thumbscrews
Silver paste is applied to thumbscrew threads on new
units at the factory to improve the electrical connection
from the battery compartment through the housing on
any SM Series transmitter. This applies to the standard
battery door and the battery eliminator.
Threads
provide
electrical
contact
The small vial contains a tiny amount (25 mg) of silver
conductive paste. A small speck of this paste will im-
prove the conductivity between the battery cover plate
thumbscrew and the case of the transmitter.
The tiny vial is about
1/2 inch tall and
contains 25 mg of
silver paste.
With improved conductivity (lower resistance) more of
the battery voltage can get to the internal power sup-
plies causing reduced current drain and longer battery
life. Though the amount seems very small, it is enough
for years of use. It is, in fact, 25 times the amount that
we use on the thumbscrews at the factory.
To apply the silver paste, first completely remove the
cover plate from the SM housing by backing the thumb-
screw completely out of the case. Use a clean, soft
cloth to clean the threads of the thumbscrew.
NOTE: DO NOT use alcohol or a liquid cleaner.
Simply hold the cloth around the threads and turn the
thumbscrew. Move to a new spot on the cloth and do it
again. Do this until the cloth remains clean. Now, clean
the threads in the case by using a dry cotton swab (Q-
tip) or equivalent. Again, clean the case threads until a
fresh cotton swab comes away clean.
Open the vial, and transfer a pinhead speck of silver
paste to the second thread from the end of the thumb-
screw. A easy way to pickup a speck of paste is to
partially unfold a paper clip and use the end of the wire
to acquire a tiny bit of paste. A toothpick will also work.
An amount that covers the end of the wire is sufficient.
Apply paste to second thread
from end of thumbscrew
It is not necessary to spread the paste more than a little
bit on the thread as the paste will spread itself every
time the thumbscrew is screwed in and out of the case
during battery changes.
Do not apply the paste to any other surfaces. The cover
plate itself can be cleaned with a clean cloth by rubbing
the slightly raised rings on the plate where it contacts
the battery terminal. All you want to do is to remove any
oils or dirt on the rings. Do not abrade these surfaces
with a harsh material such as a pencil eraser, emery
paper, etc., as this will remove the conductive nickel
plating and expose the underlying aluminum, which is a
poor contact conductor.

LectroRM
By New Endian LLC
LectroRM is a mobile application for iOS and Android
operating systems. Its purpose is to remotely control
Lectrosonics transmitters, including:
• SM Series
• WM
• L Series
The app remotely changes settings on the transmit-
ter through the use of encoded audio tones, which
when received by the attached microphone, will alter
the configured setting. The app was released by New
Endian, LLC in September 2011. The app is available
for download and sells for about $20 on the Apple App
Store and Google Play Store.
LectroRM’s remote control mechanism is the use of
an audio sequence of tones (dweedles) that are inter-
preted by the transmitter as a configuration change. The
settings available in LectroRM are:
• Audio Input Gain
• Frequency
• Sleep/Unsleep
• Lock Mode
• Power Output
• Low Frequency Roll-off
• LEDs On/Off
User Interface
The user interface involves selecting the audio se-
quence related to the desired change. Each version has
an interface for selecting the desired setting and the
desired option for that setting. Each version also has a
mechanism to prevent accidental activation of the tone.
iOS
The iPhone version keeps each available setting on a
separate page with the list of options for that setting.
On iOS, the “Activate” toggle switch must be enabled to
show the button which will then activate the audio. The
iOS version’s default orientation is upside-down but can
be configured to orient right-side up. The purpose for
this is to orient the device’s speaker, which is at the bot-
tom of the device, closer to the transmitter microphone.
Android
The Android version keeps all settings on the same
page and allows the user to toggle between the activa-
tion buttons for each setting. The activation button must
be long pressed to activate. The Android version also
allows users to keep a configurable list of full sets of
settings.
Activation
For a transmitter to respond to remote control audio
tones, the transmitter must meet certain requirements:
The transmitter must not be turned off; it can how-
ever be in sleep mode.
The transmitter must have a firmware version that
includes the remote control functions.
The remote control mode must be enabled in the
setup screen.
The transmitter microphone must be within range.
Please be aware this app is not a Lectrosonics
product. It is privately owned and operated by

that requires factory repair. It may be possible to operate on
another frequency far removed from the one that was selected
when PLL appeared on the display.
TRANSMITTER WON’T RESPOND TO REMOTE CONTROL
1) If LCD blinks “rc oFF”, transmitter has not been configured
to respond to the remote control.
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 input gain on the transmitter.
4) Make sure volume of the remote device and proximity of
microphone are sufficient to engage transmitter.
5) Make sure transmitter is not in Sleep mode.

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 at-
tempt 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 dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
