Gyraf Audio G24
GYRATEC XXIV CADMIUM COMPRESSOR
The Gyratec 24 Passive/Aggressive is an optical compressor based on re-thinking large parts of the traditional compression concept. First of all: It's passive. Really. In passive mode, your audio will only pass through one resistor, one audio transformer, one opto cell, and the output level potentiometer. kept this simple in order to mess minimally with your material. This of course comes at a cost: The input/output impedance requirements for interfacing to the G24 are quite strict, but no worries: At the "Bypass" switch, Gyraf has added one further step: "Active", which switches in a very-high-grade unity-gain buffer that will drive even the most difficult load (G21's anyone?). Solid state, yes - and invisible.
Rethinking transparent compression
The G24 is an entirely new type of stereo compressor – aimed at mix and mastering functions. Similar to its sister and predecessor, the G23 EQ, it’s for those situations where you have a mix that is already nearly-perfect balanced, but you want to control some part of its dynamic without messing up the overall definition. Gentleness and subtlety were again Gyraf’s main design targets here: This compressor is based on a carefully designed fully passive signal path, consisting of one metal film resistor, one audio transformer and one photo resistor per channel. That’s it. Nothing more. Yes, the elaborate sidechain and controls need active electronics (and thus a power supply, contrary to G21) – but all these analogue engines only ever interact with your audio by directing a bit of light to an array of photo resistors dragging that channel towards one or the other phase of the opposite channel signal. Nothing else. Gyraf believes this to be the most important innovation in the G24, the passive audio path – inspiration and technology borrowed from the notorious G21. But this is far from the only innovation that sets it apart from every other compressor out there: Most of its intricate control system was conceived from scratch, following a stringent “what-if” paradigm of research, trial and error.
Gyraf Audio G24 Passive/Aggressive Compressor Main Features:
- Completely passive signal path
- Dual sidechain, which effectively means there are two available compressors that act upon the source.
- Gradually variable all the way from L/R to M/S
- Continuously variable compression characteristic between FeedForward and FeedBack
G24 is M/S, two sets of controls – and passive. There is an option to buffer output to ensure drive capability for difficult loads if such are encountered. G21 anyone? Bypass is as always full-relay, and G24 has an output trim function for easing comparison between direct and processed material.
The G24 is as standard available as 230V or 115V mains voltages – Please specify when ordering.
'The Catch…
As you may or may not know, optical compressors can no longer be sold in the EU or California. No execptions. The industry (of which I’m part) is trying to ignore this away, and the G24 was conceived as a protest against an environmental legislation that allows massive amounts of Cadmium for batteries, yet bans an entire division of audio processing in order to save the environment from the very-small amounts of Cd in these OptoCouplers. All very technical and sad, don’t get me started… The “Aggressive” part of the unit’s name comes not from it’s way of behaving, but from my aim of stirring up the soup to get some sort of focus on the unbearable situation for real pro audio because of these rules…What it sums up to is the fact that the G24 is not really for sale, as we can’t sell you it’s heart – the CdS cell. We will need to remain legal owners of that central part, and only only lease it to you temporarily.
That is; You want one, we will need you to sign an agreement that we own the heart, and that at some time (if ever), when we have found a suitable replacement material and shipped you a module containing a new and legal part, that you will open the unit, plug the new one in, and send the old one home to us. We have arranged a disposal ritual as a small yellow-orange dot on a piece of pottery from a local artist – this is one of the legal uses of cadmium. So prepare for some paperwork if you’re in the EU or California like 95% of our customers.'
