GE570 General Description


The DynamEQ® II product family is a second generation Wide Dynamic Range Compression (WDRC) system.

GE570 incorporates 24 dB/oct filtering and is designed to accommodate CIC and ITC size requirements. The gain and frequency response is dependant on the user's environment.

Twin averaging detector circuits are optimized for sound quality during normal listening without sacrificing comfort during sudden loud inputs.

All input signals to DynamEQ® II, are processed by 2:1 compression before subsequent band splitting. The 24 dB/oct band split filter ahead of the expander/ compressor circuits allows for independent compression ratio adjustment (1:1 to 4:1) in high and low frequency channels. The gain setting stage is followed by a class D integrated receiver preamplifier stage. Symmetrical peak clipping is used to achieve MPO adjustment.
