DESCRIPTION
The DynamEQ
growth equalizer. Its gain and frequency response is
dependent on the user's environment, and is designed for
level dependant frequency response providing
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
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.
