GM3036 Programmable
DynamEQ®II Hybrid
DATA SHEET
DESCRIPTION
The GM3036 programmable hybrid is composed of a
DynamEQ®II Wide Dynamic Range Compression signal
processor and the GP522 controller memory chip. The
hybrid incorporates 24 dB/oct filtering.
The gain and frequency response are dependent on the user’s
environment. The Twin Average Detector circuit is optimized
for sound quality during normal listening without sacrificing
comfort during sudden loud sounds.
The GM3036 features six programmable parameters:
independent compression ratio adjustment in the High and
Low frequency channels, VC adjustment, threshold
adjustment, crossover frequency adjustment and MPO
adjustment.
The output stage is designed as a preamplifier for the class D
integrated receiver.
