Dynamic Equalizer-Reflowable
GS3030 - DATA SHEET
FEATURES
DESCRIPTION
• handles high input levels (up to 100 mVRMS)
cleanly
TheDynamEQ® -1hybridisadynamicallyadaptiveloudness
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
DynamEQ®-1has twosignalpathsfordualchannelprocessing
incorporating 4 amplifying stages ( A, B, C, D ) and the
AGC processing circuit.
• 26% smaller than original DynamEQ® -1 GS3011
STANDARD PACKAGING
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.
• Hybrid Typical Dimensions
