Gyratec G22: Stereo/Dual/MS Vari-mu Compressor

Gyratec G22: Stereo/Dual/MS Vari-mu Compressor

G22 is an elaborated and dualified version of our venerable G10 vari-mu compressor. It can be set to dual-mono, but still keeps a backwards-compatibility “G10 mode” where one set of knobs controls real stereo, like you’d want most of the time in mastering.

The G22 is as standard available as 230V or 115V mains voltages – Please specify when ordering

Two-in-one

The G22 is a dual-channel unit – allowing you to use it as two compressors on two different signal sources. It’s still a fully stereo-linked compressor with all the freedom and ease of control this gives you.

SKU: g22-1 Category: A simple sidechain high-pass filter was added (located on the bypass switch) which cuts off compressor keying below ca. 80Hz at a slope of 6dB/oct. This mainly to keep pumping artifacts under control when working fast in bass-heavy material. Input and output transformers can be switched between standard two-channel L/R mode and the M/S mode where both matrixing and dematrixing done is internally: M/S mode allows you to independently control dynamics (and levels) in mono and side parts of program material and still have the result on the output as standard stereo information. Linking/dynamic interaction between channels in dual-mode can be set continuously from none to full by the Vari-link control knob - enabling you to dial in a difference in channel processing, and then varying difference amount in a simple mode. When initially getting to learn the unit, I myself was amazed how intuitive this control worked. Bypass is, off course, hard and relay-based. You bypass, G22 acts only like an additional piece of cable. The audio part of the circuit is a faithful reproduction of the G10 that has been our flagship for more than 15 years - if it works, don't fix it. The only minor change is a re-bias of the output stage, which allows some 4-5dB more headroom while preserving the original stage's soft transition into overload. Some changes has been made to the sidechain functions, including a wider threshold range (to allow S compression in weak-S M/S-mode) and even faster fastest attack time (because we can, it's a vari-mu you know...)
