Lectrosonics SSM Overview

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.

The SSM transmitter tunes across a range of over 76 MHz. This tuning range covers three standard Lectrosonics frequency blocks
The transmitter operates from a 3.7V rechargeable battery that will provide about four hours of operation per charge
The factory-supplied battery charger provides a folding NEMA 2-prong plug, and will operate from 100-240 VAC sources. The LED glows red during charging and turns green when the battery is fully charged
The LCD is a numeric-type Liquid Crystal Display with screens for adjusting output power, frequency, audio level, low frequency audio roll-off, and various modes and options
The antenna is a flexible whip made of galvanized steel, permanently attached to the transmitter to prevent damage from heavy use. The IR port is capped with a translucent dome material to broaden the reception angle. The input jack is a rugged 3-pin LEMO connector with a threaded locking sleeve
An infrared sync port on the SSM allows for quick setup with compatible receiver systems. A micro-B USB port makes it possible for firmware updates in the field as advanced features are added in the future
The SSM responds to remote commands for frequency, audio level, sleep modes, and other settings from the RM remote unit or 3rd party smartphone apps

Greater than 1 V maximum, with limiting
Input ImpedanceMic: 300 or 4.5 kOhms; selectable
Line: Greater than 100 kOhms
Input LimiterDSP controlled, dual envelope "soft" limiter with greater than 30 dB range
Gain Control Range44 dB; digital control
Modulation IndicatorsDual bicolor LEDs indicate modulation of -20, -10, 0 and +10 dB referenced to full modulation
Audio Performance
Frequency Response35 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 RatioAt 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
