Consumer Alert for US Users - FCC Order DA 10-92
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it
must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received
from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC
(TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones.
To operate wireless microphone systems at power greater than 50mW, you must qualify as a Part 74 user and be
licensed. If you qualify and wish to apply for a license go to: http://www.fcc.gov/Forms/Form601/601.html

Introduction
Three Block Tuning Range
The SSM transmitter tunes across a range of over 76
MHz. This tuning range covers three standard Lectrosonics frequency blocks.
TUNING RANGE
BLOCK
BLOCK
BLOCK
Four bands are available covering standard blocks as
follows:
Band Blocks Covered Freq. MHz
A1 470, 19, 20 470.100 - 537.575
B1 21, 22, 23 537.600 - 614.375
B2 22, 23, 24 563.200 - 639.975
C1 24, 25, 26 614.400 - 691.175
To simplify backward compatibility with earlier Digital
Hybrid Wireless
®
equipment, block numbers are pre-
sented along with frequencies in LCD screens.
About Frequency Blocks
A 25.6 MHz band of frequencies, referred to as a
Block, came about with the design of the first frequency
tunable Lectrosonics wireless products. These products provided two 16-position rotary switches to select
frequencies as shown in the illustration below. A logical
method of identifying the switch positions was using 16
character hexadecimal numbering. This naming and
numbering convention is still used today.
The 16 switch positions are numbered 0 (zero) through
F, presented in a two-character designation such as
B8, 5C, AD, 74, etc. The first character indicates the
position of the left hand switch and the second character indicates the position of the right hand switch. This
designator is commonly called a “hex code.”
About Digital Hybrid Wireless
®
US Patent 7,225,135
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, however, it is often at the cost of one
or more issues regarding 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 Wireless 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.

100kHz
On older transmitter models, the left hand
switch makes steps in 1.6 MHz increments,
the right hand switch in 100 kHz increments.
Each block spans a 25.6 MHz band. A simple formula
is used to name the blocks according to the lowest frequency in each one. For example, the block starting at
512 MHz is named Block 20, since 512 divided by 25.6
equals 20. Special blocks were created later in different frequency bands using the lowest frequency in the
block as the designator.

Battery Charging
The transmitter operates from a 3.6 V rechargeable
battery that will provide about six hours of operation
per charge. Battery life can be monitored from the timer
function built into current Lectrosonics receivers.
The factory supplied battery charger kit provides a
folding NEMA 2-prong plug on the charger, and will
operate from 100-240 VAC sources. The LED glows red
during charging and turns green when the battery is
fully charged. The kit includes a Euro plug adapter and
vehicle auxiliary power adapter cord.

for simple and quick battery changes, yet prevent the
door from being opened accidentally.

SSM
Controls and Functions
Modulation
LEDs
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.
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
Greater than +10 db Red Red
LCD Screen
The LCD is a numeric-type Liquid Crystal Display with
screens for adjusting output power, frequency, audio
level, low frequency audio roll-off and various modes
and options. The transmitter can be powered up with or
without the RF output turned on. A brief press on the
power button turns the unit on in a Standby Mode with
the output turned off to allow adjustments to be made
without interfering with other wireless systems in the
vicinity.
WARNING: Moisture, including talent’s sweat,
will damage the transmitter. Wrap the SSM in
a plastic baggie or other protection to avoid
damage.
BATT LED
Power Button
Red Green
BATT LED
This LED glows green when the battery is good. The
color changes to red when there is only a few minutes
of operation left. The LED will blink briefly, just before
the unit powers down.
The exact point at which the LED turns red will vary
with battery brand and condition, temperature and current drain. The LED is intended to simply catch your
attention, not to be an exact indicator of remaining time.
AUDIO Button
The AUDIO button is used to adjust the audio output
level and low frequency roll-off. Each press of the button
will toggle between the two settings.
FREQ Button
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
Lectrosonics Frequency Switch Setting.
Power Button
Turns the unit on and off. A brief press turns power on
in a Standby Mode to make settings without interfering
with other wireless systems in the vicinity. Pressing and
holding the button until a counter on the LCD completes
a sequence turns the power on with the RF output
turned on. Pressing and holding for the duration of a
countdown turns the unit off.
UP and 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. Press and hold both buttons until a
countdown is completed to lock the keypad. Remove
the battery to unlock the keypad.
Turning LEDs ON and OFF
These arrow keys also turn the LEDs on and off. With
no other button pressed, the UP arrow turns the LEDs
on and the DOWN arrow turns them off. When the LEDs
are tuned off, the LCD will display a reminder every few
seconds.

Screens for compete information.
