The transmitter's microcontroller automatically sets the modulation for companding or non-companding audio processing when the corresponding channels are selected. The channel selection also sets either narrow-band operation on channels 1-40 (5 kHz deviation) or high-fidelity, wide-band operation on channels 41-60 (10 kHz deviation). The optional microphone mute switch turns off the microphone without turning off the aux input.

Option 1: With Microphone Mute switch.
