The amplitude-limited MIC signals are output from pin 5, then applied to the base band IC (IC5, pin 3). The applied MIC signals are amplified at the amplifier (TXA1), and level adjusted at the volume controller (VR1). The level adjusted MIC signals are applied or bypassed the compressor section, pre-emphasis section, TX/RX HPF, de-scrambler, limiter, splatter, in sequence, then applied to another volume controller. The compressor compresses the MIC signals to provide high S/N ratio for receive
