GS3030 - DATA SHEET
DESCRIPTION
The DynamEQ
-1 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.
DynamEQ
-1 has two signal paths for dual channel processing
incorporating 4 amplifying stages ( A, B, C, D ) and the
AGC processing circuit.
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.
