The enhanced compressor/limiter is a dual channel unit in a steel chassis six inches deep and one rack unit high. There shall be a front panel switch to link the channels to track as a stereo pair. Each channel shall have a pair of LEDs for indicating above or below threshold, and a 5 segment LED gain reduction display, plus variable controls for threshold, ratio and output gain. Attack and release times shall be program dependent. Each channel shall also have a hardwire Bypass switch on the front panel, and a switch to control the enhance circuit. This circuit shall provide low frequency enhancement at 50 Hz, and High frequency enhancement at 10 KHz.
