1. Compressor unit
The compressor unit consists of the mike amp, compressor, limiter circuit, data amp, and mute circuit.
The mike amp gain can be adjusted through an external resistance, and so the mike amp can be
connected directly to a microphone. An internal limiter circuit to prevent overmodulation as well as a data
amp (0dB amp) enabling transmission of data signals without compression are also provided. Switching
between audio signals and data signals is possible using the compressor mute switch.
2. Expander unit
The expander unit consists of an input amp, expander, and mute circuit.
The input amp makes available all input and output signals at pins, and so can be used freely as an
amplifier, filter amp, or data amp. When used as a data amp, the expander mute switch can be set so that
the expander output is nearly silent.
