The SSM is ideal in theatrical or any other production where concealment in costuming is required. In spite of its tiny size, the transmitter offers an extensive feature set and performance on par with all of the Digital Hybrid Wireless models. Frequencies are selectable in 100 kHz or 25 kHz steps across a maximum tuning range of 76.7 MHz. This yields a total of 3072 available frequencies across three standard frequency blocks. The tuning range varies in some blocks to meet applicable frequency allocations.

Power is provided by a rechargeable Lithium-ion battery. The formed stainless steel battery door latches closed securely and cannot be jarred open accidentally. The servo bias input accepts mic or line level signals with a wide range of gain adjustment in 1 dB steps. Accurate LED indications on the keypad 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. Compatibility with earlier analog Lectrosonics receivers, Lectrosonics IFB receivers and some receivers from other manufacturers is provided by DSP emulation modes selected in the LCD menu. The housing is constructed of machined aluminum, finished with an ultra hard, black electroless nickel finish called ebENi.

The audio input jack is a LEMO 00 Series 3-pin connector, common in theatrical production. A threaded collar adds additional ruggedness. An IR (infrared) port next to the antenna allows transfer of frequency and compatibility mode settings from IR enab
