Lectrosonics SSM Miniature Digital Hybrid Wireless Belt-Pack Transmitter
The SSM transmitter 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.
Features
- Tunable across three standard frequency blocks (76.8 MHz)
- Digital Hybrid Wireless® audio for compandor-free digital quality
- High quality 3-Pin lemo connector for microphone input
- Selectable 25 or 50 mW RF power
- Compatibility modes for use with analog receivers
- 25 or 100 kHz tuning steps for up to 3072 selectable frequencies
- Wide range input gain control in 1 dB steps
- Quick change Lithium-ion rechargeable battery
- Audio coupled remote control
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.
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.
Frequency ranges:
- A1 - 470-537 MHz*
- B1 - 537-614 MHz
- B2 - 563-640 MHz
- C1 - 614-691 MHz*

*Note: The dual envelope ""soft"" limiter provides the handling of transients using variable attack and release time constants. Once activated, the limiter compresses 30+ dB of transmitter input range into 4.5 dB of receiver output range, thus reducing the measured figure for SNR without limiting by 4.5 dB
