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 other blocks to meet applicable frequency allocations.

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.

Along with providing peerless audio quality with wide frequency response and dynamic range in Nu Hybrid mode, the technology used in the SSM includes compatibility modes for Lectrosonics Mode 3 and IFB receivers.

* Digital Hybrid Wireless™ is a revolutionary new design that combines 24-bit digital audio with an analog FM radio link to provide outstanding audio quality and the extended operating range of the best analog wireless systems. The design overcomes channel noise in a dramatically new way, digitally encoding the audio bitstream in the transmitter and decoding it in the receiver, yet sending the encoded information via an analog FM wireless link. This proprietary DSP algorithm eliminates a compandor circuit and its artifacts and preserves the RF spectral footprint of analog FM designs to simplify multi-channel coordination with existing analog wireless systems.
