Gyraf Audio Gyratec XXIII - Equalizer

  • Equalizer aimed mainly at mix and mastering
  • Option for selection between all-solid-state technology or classic tube circuitry
  • Designed around a highly linear 1dB/oct slope filter
  • Gentleness and subtlety are G23-S design targets

The Gyraf Audio G23-S Equalizer is an update of the G23 Equalizer, in which Graf have added a selectable option for either solid-state or tube audio path. Like the standard G23, its aimed at the situations where you have a mix that is already nearly-perfect balanced, but you want it a tad darker or brighter without altering the overall definition.

Gyraf added an additional step to the bypass switch - marked "S" - which instantly shifts you into solid-state land: Inputs become differential instrumentation type instead of transformer, active equalizer stage gets controlled by a state-of-the-art opamp, and output stage gets servo-balanced instead of tube/transformer drive.

What sets the G23-S apart from all other EQ designs is that it is designed around a highly linear 1 dB/oct slope filter, so that rotating the control will tip an almost ruler-straight response curve, to a maximum steepness of 1 dB/oct. What is achieved in the 1dB/oct function is the ability to "spread out" or distribute the "needed" phase roll across the whole spectrum, meaning that at any given interval, only minute amounts of group delay are apparent. In total, it allows quite some correction without sounding too "EQed". And because you'd occasionally want to correct outer ends of spectrum, Gyraf have added a gentle Baxandall tone control, shelving lows and highs, wide-Q bell mid, each at three selectable optimized frequencies.

Gentleness and subtlety were main design targets here: highs at 4 dB, mids at 2 dB, and lows at 6.5 dB.
