The circuit consists of a newly designed AGC preamplifier and output stage, capable of driving the class D integrated receiver. The compression control circuit varies the current controlled resistance, connected between the input and output of the AGC preamplifier. The compression circuit operates with an 8:1 compression ratio and uses an averaging detector with a time constant of 270 ms, selected to provide optimal sound quality over the full range of sound and listening environments. The actual attack and release times are typically 40 ms and 150 ms respectively when the circuit is fully in the compression region of operation (measured times will vary depending on gain and threshold settings). The system gain and compression control can be adjusted by the choice of two independent resistors. Maximum system gain is 38 dB and it can be adjusted within a 38 dB range. The output compression threshold can be adjusted within a 16 dB range. BLOCK DIAGRAM All resistors in ohms, all capacitors in farads unless otherwise stated.
