Introduction

The DSSM is the enhanced, fully digital successor to the
SSM, while being IP57 rated for moisture and particulate
resistence and offering dock charging capability.
The DSSM is ideal in theater, TV, film and broadcast
where concealment is desired and water-resistance is
required. The DSSM offers an extensive feature set and
performance packed into an exceptionally compact
housing, compatible with all current Lectrosonics digital
receivers, including the DSR, DSR4, DSQD, DCR822,
M2Ra and DCHR.
The DSSM includes specially developed, highly efficient
circuitry for extended operating time on the rechargeable
LB-50 battery. RF power selections are offered at 10 and
35 mW (D2 compat mode) and a special high density
(HDM) mode at 2 mW.
The servo bias input accepts mic or line level signals with
a wide range of gain adjustment in 1 dB steps. Accurate
indications on the display allow precise gain adjustments
to be made for the maximum signal to noise ratio and
minimum distortion. The limiter in the preamp can cleanly
handle signal peaks over 30 dB above full modulation,
allowing the input gain to be set high enough to achieve
the maximum signal to noise ratio, yet provide protection
against input overload.
The audio input jack is a common miniature 3-pin con-
nector with a threaded collar adding additional rug-
gedness. An IR (infrared) port next to the SMA antenna
mount allows transfer of frequency and compatibility
mode settings.
The membrane switch panel and OLED display enable
access to all adjustments and settings. The menu struc-

ture is easy to navigate. Battery status is indicated by a
bi-color LED that is green with a fresh battery, then turns
to red as the battery runs down, and finally starts blinking
red when there are only a few minutes of runtime remain-
ing.
The housing is constructed of machined aluminum alloy,
treated in the conductive, super hard electroless nickel
ebENi finish.
A flexible, repositionable wire belt clip (to orient the an-
tenna facing up or down) is included.
The optional CHSDSSM battery charging station (shown
below) provides a convenient and organized means of
recharging up to 4 LB-50 batteries or DSSM transmit-
ters in larger systems with numerous batteries in regular
use. Each charging module may be daisy-chained to 3
CAUTION: DO NOT REMOVE the threaded
screw where indicated, as that will void the
warranty and IP rating.
