THE GYRAF FAMILY:
G9 DUAL TUBE MICROPHONE AMPLIFIEROur classic dual tube microphone amplifier.
The G10 is a true tube stereo compressor based on the classic variable-mu principle. two channels, a single set of controls.
The G14 is our classic five band all passive stereo equaliser – with selection of either classic tube or modern solid-state technology.
This eq is a truly passive design based on switching a set of inductors and capacitors in and out of circuit combined with a linear make-up gain and output stage that can be either based on tubes and transformers OR solid-state and servo balanced.
The G21 is a fully passive, stereo, three band audio clipper. Although originally intended for loudness optimization, it excels in cleaning up individual parts of audio spectrum without applying heavy-handed equalization. All this resulting in very subtle sounding operation – perhaps it’s easiest to think of it as a dynamic subtractive eq without time constants. Expect some learning curve on this one..
The G22 is the classic and loved vari-mu compressor spiced up with a m/s-matrix and dual sets of controls. Needing only one set of knobs for stereo operation in backward compatibility mode, it also provides dual- and M/S operations with “vari-link” continuous GR control linking between channels – and provide very precise compression user control.
The G23-S stereo tilt equalizer is an original idea of ours – the first ever equalizer based on fully linear one db/oct filters. The way we implement filtering allows for very gentle overall tonal corrections without loosing much subjective phase coherence or mix integrity. All-tube signal path, or modern solid-state technology, accessible with the flip of a switch.
The G24 “passive/aggressive” compressor is the world’s first passive compressor with dual stereo/MS function.
It is based on a double set of controls enabling it to act as two linked mono compressors. Also the first compressor to continuous blend between feedforward and feedback topologies. Note that ordering involves sending in an application in EU and CA.
