DynamEQ^®I

Dynamic Equalizer

GS3020 - DATA SHEET

FEATURES

DESCRIPTION

• handles high input levels (up to 100 mVRMS)

cleanly

The DynamEQ^®I hybrid is a dynamically adaptive loudness

growth equalizer. Its 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.

• low THD and IMD distortion

• unique twin average detectors

• dual channel signal processing

• adjustable AGC threshold levels

• highpass filter with adjustable corner frequency

• 2:1 compression of high frequencies

• no external capacitors or resistors required

DynamEQ^®Ihastwosignalpathsfordualchannelprocessing

incorporating 4 amplifying stages ( A, B, C, D ) and the

AGC processing circuit.

• 30% smaller by volume than DynamEQ^®I GS3011

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 class A power amplifier with receiver

bias current adjustment.
