General Description

The Williams Sound MOD 232-02 is an infrared modulator that is microprocessor-controlled and handles two audio channels .Baseband outputs can daisy-chain two MOD 232 together for four-channel operation, and combination jack inputs provide balanced/unbalanced line-level inputs.
Carrier frequencies are controlled by the microprocessor and a frequency synthesizer.

The MOD 232-02 modulator is ideal for audio description, hearing assistance or simultaneous interpretation.
