The Lectrosonics SSM is perfectly suitable in theatrical or any other production where concealment in costuming is required. Even the Lectrosonics SSM has 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.
The Lectrosonics SSM has two frequency range:
- SSM A1: 470.100 to 537.575 MHz
- SSM B1: 537.600 to 614.375 MHz

Operating Frequency | A1: 470.100 to 537.575 MHz / B1: 537.600 to 614.375 MHz |
Frequency Selection Steps | Selectable; 100 kHz steps or 25 kHz |
RF Power Output | Switchable; 25 or 50 mW |
Pilot Tone | 25 to 32 kHz; 5 kHz deviation (Digital Hybrid mode) |
Frequency Stability | ± 0.002% |
Deviation | ± 75 kHz max. (Digital Hybrid mode) |
Spurious Radiation | 60 dB below carrier |
Equivalent Input Noise | -120 dBV, A-weighted |
Input Level | Nominal 2 to 300 mV, before limiting Greater than 1 V maximum, with limiting |
Input Impedance | Mic: 300 or 4.5 kOhms; selectable Line: Greater than 100 kOhms |
Input Limiter | DSP controlled, dual envelope "soft" limiter with greater than 30 dB range |
Gain Control Range | 44 dB; digital control |
Modulation Indicators | Dual bicolor LEDs indicate modulation of -20, -10, 0 and +10 dB referenced to full modulation |
Frequency Response | 35 Hz to 20 kHz (+/-1 dB) |
Low Frequency Roll-Off | -12 dB/octave; 70 Hz |
Total Harmonic Distortion (THD) | 0.2% (typical) |
Signal to Noise Ratio | At Receiver Output: SmartNR Off: No limiting 103.5, w/limiting 108.0 SmartNR Normal: No limiting 107.0, w/limiting 111.5 SmartNR Full: No limiting 108.5, w/limiting 113.0 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 |
