This WDRC (Wide Dynamic Range Compression) system can be easily configured to provide either a TILL (Treble Increases at Low Level) or wideband response. Twin averaging detector circuits drastically reduce the pumping effects associated with traditional fast attack/slow release systems. The fast detection circuitry cuts in to control the output level during impulsive sounds, but quickly backs out of the way during normal operation. Low distortion, large signal handling capabilities and constant corner frequncy make it ideal for providing loudness growth compensation for many of the mild to moderate cases. The size of the hybrid and variety of electrical access points, offers system design flexibility perfect for ITC and CIC applications. Stage A is a highpass channel with 2:1 compression, Stage B is a wideband unity gain buffer. The sum of the two paths gives a high frequency boost to low level signals, which gradually compresses to a flat response at high input levels. Stage C is used for volume control adjustment, while stage D is a fixed gain stage with MPO control designed to drive class D integrated receivers.
