GS3020

The DynamEQ^® I hybrid GS3020 is a dynamically adaptive loudness growth equalizer. GS3020's gain and frequency response is dependent on the user's environment, and is designed for level dependant frequency response providing treble increase at low levels (TILL). The unique twin averaging detector circuit dramatically reduces pumping effects and is optimized for mild to moderate hearing loss.

DynamEQ^® I GS3020 has two signal paths for dual channel processing incorporating 4 amplifying stages ( A, B, C, D ) and the AGC processing circuit.

Stage A of GS3020 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 of GS3020 is used for volume control adjustment, while stage D is a class A power amplifier with receiver bias current adjustment.
