Lectrosonics SSM (A1: 470.100 - 537.575 MHz)

The SSM from Lectrosonics is a miniature Digital Hybrid Wireless Transmitter with selectable frequencies across a maximum tuning range of 76.7 MHz and has selectable 25 or 50 mW RF output power. It can be used in applications where concealment in costuming is required or any other production such as for live stage, theater, houses of worship, reality TV, and more.

The SSM features selectable frequencies in 100 kHz or 25 kHz steps yielding a total of 3,072 available frequencies across three standard frequency blocks. Its lithium-ion battery provides power and sits in a stainless-steel battery door that latches closed and cannot be jarred open accidentally.

The servo bias input that is built into the transmitter accepts mic or line level signals and uses gain adjustments in 1 dB steps. The LED indicators on the membrane keypad allow you to monitor precise gain adjustments and settings. A built-in limiter in the preamp, handles signal peaks over 30 dB. This provides you with the maximum signal to noise ratio and minimum distortion for input, but still provides protection against input overloads.

The SSM is compatible with earlier analog Lectrosonics receivers IFB, and some other receivers, from manufacturers that utilize the DSP emulation mode, which is selectable in the LCD menu. The SSM transmitter housing is constructed of machined aluminum and has a hard, black electroless nickel finish called ebENi.
