Introduction to DSSM
signal to noise ratio, yet provide protection against input overload.
The audio input jack is a common miniature 3-pin connector with a threaded
collar adding additional ruggedness. An IR (infrared) port next to the SMA an-
tenna mount allows transfer of frequency and compatibility mode settings.
The membrane switch panel and OLED display enable access to all adjust-
ments and settings. The menu structure 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 remaining.
The housing is constructed of machined aluminum alloy, treated in the conduc-
tive, super hard electroless nickel ebENi finish.
A flexible, repositionable wire belt clip (to orient the antenna facing up or down)
is included.

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 exception-
ally 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 indica-
tions on the display allow precise gain
adjustments to be made for the maximum
signal to noise ratio and minimum distor-
tion. 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
