GC2020BII
Dual channel compressor/ limiter

A superb dual-channel compressor/limiter
This is for the home studio and small production facility.

A high-performance unit
This unit can be effectively used in recording, sound reinforcement, broadcasting and other production applications.

The GC2020BII offers a wide variety of control features
This is for precise tailoring of compression and limiting parameters, and it also features an expander type noise gate in each channel for effective noise reduction.

All this with exceptionally high audio quality
Full 20Hz to 20kHz frequency response and no more than 0.05% total harmonic distortion.
