THE GYRAF FAMILY:
G25 VocalShape RECORDING CHANNEL
NEW – 12/2023: The G25 “VocalShape” is our elaborate all-in-one box for vocal recording. It is an all-tube unit, consisting of a pre-amplifier stage, a filter and an equalizer section, a compressor, and finally a single stage of frequency-selective clipping for control of resonances. Every and all parameters optimized for – and only for – recording vocals.
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 a signed application inside EU and CA.
G23-S STEREO TILTING EQUALIZER
The G23-S stereo tilt equalizer is an original idea of ours – the first ever equalizer based on fully linear transfer function, up to one db/oct. This allows for very gentle brighter/darker tonal corrections without loosing subjective phase coherence or mix integrity. All-tube signal path, or modern solid-state technology, accessible at the flip of a switch.
G22 DUAL/STEREO/MS VARI-MU COMPRESSOR
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.
G21 MAGNETO-DYNAMIC INFUNDIBULUM
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..
G14-S PARALLEL-PASSIVE STEREO TUBE EQ
The G14 is our classic five band all passive stereo equalizer – with added selection of either classic tube or modern solid-state technology for the amplification duties. This eq is a true passive design based on switching sets 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 / servo balanced.
The G10 is a true tube stereo compressor based on the classic variable-mu principle. Stereo unit with a single set of controls – for those that don’t enjoy fiddling with dual-mono. Essentially unchanged over the past 25 years. Note that the G22 is a dualification of this exact circuit design.
G9 DUAL TUBE MICROPHONE AMPLIFIER
G9 is our classic dual tube microphone amplifier – two tubes in each channel performs all the needed amplification.
