FEATURES
DEVICE DESCRIPTION
• dual channel signal processing
The DynamEQ® II hybrid family is a second generation Wide
Dynamic Range Compression (WDRC) system.
• 2nd (4th) order state variable filter
• adjustable crossover frequency
GS3031 (GS3032) hybrid incorporates 12 dB/oct (24 dB/oct)
filtering. All capacitors necessary for operation are included
on the hybrid.
• adjustable compression ratio from 1:1 to 4:1
• independent compression ratio adjustment for
low and high frequency band
The gain and frequency response is dependant on the user’s
environment.
• adjustable AGC threshold levels
• unique twin average detectors
• handles high input levels
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.
• low THD and IMD distortion
• drives Class D Integrated Receivers
• MPO range externally adjustable
The 12 dB/oct (24 dB/oct) band split filter ahead of the
e xp a nd e r/c omp re s s or c irc uits a llows for ind e p e nd e nt
compression ratio adjustment (1:1 to 4:1) in high and low
frequency channels.
STANDARD PACKAGING
Hybrid Typical Dimensions
0.250 in x 0.115 in x 0.080 in)
(6.35 mm x 2.91 mm x 2.03 mm)
The gain setting stage is followed by a class D Integrated
Receiver preamplifier stage. Symmetrical peak clipping is
used to achieve MPO adjustment.
