lease, or sold or leased, until authorization is obtained.
Quick Start Steps
1) Install a good battery and turn power on (see pages
5 and 9).
2) Set the compatibility mode to match the receiver
(see page 8).
3) Connect the signal source and adjust input gain for
optimum modulation level (see pages 10 and 11).
4) Set Step Size and frequency to match receiver.
Also see receiver manual for scanning procedure to
find a clear operating frequency.

conjunction with any other antenna or transmitter.
Industry Canada Notices:
Per RSS-210
This device operates on a no-protection no-interference basis. Should the user seek to obtain
protection from other radio services operating in the same TV bands, a radio licence is required.
Please consult Industry Canada’s document CPC-2-1-28, Optional Licensing for Low-Power Radio
Apparatus in the TV Bands, for details.
Per RSS-Gen
This device complies with Industry Canada’s lecence-exempt RSSs. Operation is subject to the
following two conditions:
1) This device may not cause interference
(2) This device must accept any interference, including interference that may cause undesired
operation of the device.
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

TUNING RANGE
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.
BLOCK
BLOCK
BLOCK
Four tuning ranges are available covering standard
blocks as follows:
Range Blocks Covered Freq. MHz
A1 470, 19, 20 470.1 - 537.5
B1 21, 22, 23 537.6 - 614.3
C1 24, 25, 26 614.4 - 691.1
D1* 27, 28, 29 691.2 - 767.9
*Export Only
To simplify backward compatibility with earlier Digital
Hybrid Wireless® equipment, block numbers are presented 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.

Battery Charging
The transmitter operates from a 3.7 V rechargeable
battery that will provide about four hours of operation
per charge. Battery life can be monitored from the timer
function built into current Lectrosonics receivers.
The factory supplied battery charger provides a folding
NEMA 2-prong plug, and will operate from 100-240 VAC
sources. The LED glows red during charging and turns
green when the battery is fully charged.
Battery Installation
The battery compartment and door catch are designed
for simple and quick battery changes, yet prevent the
door from being opened accidentally.
