GR3031/GR3032 - DATA SHEET
DEVICE DESCRIPTION
The DynamEQ
II hybrid family is a second generation Wide
Dynamic Range Compression (WDRC) system.
GR3031 (GR3032) hybrid incorporates 12 dB/oct (24 dB/oct)
filtering. All capacitors necessary for operation are included.
The hybrid was designed for reflowability.
The gain and frequency response is dependant on the user’s
environment.
Twin averaging detector circuits are optimized for sound quality
during normal listening without sacrificing comfort during
sudden loud inputs.
All input signals to DynamEQ
II, are processed by 2:1
compression before subsequent band splitting.
The 12 dB/oct (24 dB/oct) band split filter ahead of the
expander/compressor circuits allows for independent
compression ratio adjustment (1:1 to 4:1) in high and low
frequency channels.
The gain setting stage is followed by a Class D Integrated
Receiver preamplifier stage. Symmetrical peak clipping is
used to achieve MPO adjustment.
