Introduction
The design of the SMWB/E07 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 elimi-
nate a compandor and its artifacts, yet preserve the
extended operating range and noise rejection of the fin-
est 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, musi-
cal 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 con-
stant 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 informa-
tion in digital form, at the cost of some combination of
power, bandwidth, operating range and resistance to
interference.
The Lectrosonics Digital Hybrid Wireless system over-
comes 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 informa-
tion 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 in-
creased 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.
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 sev-
eral 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 instru-
ments 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/E07 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 can-
not record AND transmit at the same time. The record-
er 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.

Features
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.
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.
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.

Battery Installation
The transmitter is powered by two AA batteries. We
recommend using lithium for longest life.
Because rechargeable batteries run down quite abrupt-
ly, 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 Lectroson-
ics 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 bat-
tery life or an increase in operating temperature.
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.
Insert the batteries according to the markings on the
back of the housing. If the batteries are inserted incor-
rectly, the door may close but the unit will not operate.

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 Wir-
ing for Different Sources for details.
Turning Control Panel LEDs ON/OFF
From the main menu screen, a quick press of the UP
arrow button turns the control panel LEDs on. A quick
press of the DOWN arrow button turns them off. The
buttons will be disabled if the LOCKED option is select-
ed in the Power Button menu.
The control panel LEDs can also be turned on and off
with the LED Off option in the Power Button menu.
Helpful Features on Receivers
To aid in finding clear frequencies, several Lectrosonics
receivers offer a SmartTune feature that scans the tun-
ing 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 func-
tion allow the receiver to set frequency, step size and
compatibility modes on the transmitter via an infrared
link between the two units.

Adjusting the Input Gain
The two bicolor Modulation LEDs on the control panel
provide a visual indication of the audio signal level
entering the transmitter. The LEDs will glow either red
or green to indicate modulation levels as shown in the
following table.
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: Full modulation is achieved at 0 dB, when
the “-20” LED first turns red. The limiter can cleanly
handle peaks up to 30 dB above this point.
It is best to go through the following procedure with the
transmitter in the standby mode so that no audio will en-
ter the sound system or recorder during adjustment.
1) With fresh batteries in the transmitter, power the unit
on in the standby mode.
(see previous section: Turning Power ON)
2) Navigate to the Gain setup screen.

3) Prepare the signal source. Position a microphone
the way it will be used in actual operation and have
the user speak or sing at the loudest level that will
occur during use, or set the output level of the in-
strument or audio device to the maximum level that
will be used.
4) Use the and arrow buttons to adjust the gain
until the –10 dB glows green and the –20 dB LED
starts to flicker red during the loudest peaks in the
audio.
5) Once the audio gain has been set, the signal can
be sent through the sound system for overall level
adjustments, monitor settings, etc.
6) If the audio output level of the receiver is too high or
low, use only the controls on the receiver to make
adjustments. Always leave the transmitter gain ad-
justment set according to these instructions, and do
not change it to adjust the audio output level of the
receiver.

About Overlapping Frequency Bands
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 compat-
ibility with receivers that tune across a single band. The
band number and hex code must match the receiver to
enable the correct pilot tone.

microphone cable.
2) Slide the dust boot onto microphone cable with the
large end facing the connector.
3) If necessary, slide the 1/8-inch black shrink tubing
onto the mircrophone cable. This tubing is needed
for some smaller diameter cables to ensure there
is a snug fit in the dust boot.
4) Slide the backshell over the cable as shown above.
Slide the insulator over the cable before soldering
the wires to the pins on the insert.
5) Solder the wires and resistors to the pins on the
insert according to the diagrams shown in Wiring
Hookups for Different Sources. A length of .065
OD clear tubing is included if you need to insulate
the resistor leads or shield wire.
6) If necessary, remove the rubber strain relief from
the TA5F backshell by simply pulling it out.
7) Seat the insulator on the insert. Slide the cable
clamp over the and of the insulator and crimp as
shown on the next page.
8) Insert the assembled insert/insulator/clamp into
the latchlock. Make sure the tab and slot align
to allow the insert to fully seat in the latchlock.
Thread the backshell onto the latchlock.

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
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 sig-
nal from affecting the capsule, even though the trans-
mitter input circuitry is already RF bypassed.
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 connec-
tor 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.
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 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.

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 Level
• Frequency
• Sleep Mode
• Lock Mode
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
however be in sleep mode.
• The transmitter must have firmware version
1.5 or later for Audio, Frequency, Sleep and
Lock changes.
• The transmitter microphone must be
within range.
• The transmitter must be configured to enable
remote control activation.
Please be aware this app is not a Lectrosonics
product. It is privately owned and operated by
New Endian LLC, www.newendian.com.
