Gyraf Audio Gyratec XXIII G23-S "Ambler" Tilting Equalizer with Solid State Option

The G23-S is an elaboration of our G23 tiltinging-type Equalizer, where we added a selectable option for either solid-state or tube audio path.

Like the standard G23, it’s 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 messing up the overall definition.

The G23-S is as standard available as 230V or 115V mains voltages – Please specify when ordering

The G23-S is an updated version of our G23 – now including an option for selection between all-solid-state technology or classic tube circuitry. We added an additional step to the bypass switch - marked "S" - which instantly shifts you into solid-state land: Inputs become differential instrumentation type in stead of transformer, active equalizer stage gets controlled by a state-of-the-art opamp, and output stage gets servo-balanced in stead of tube/transformer drive

Designed around a highly linear 1dB/oct slope filter, so that rotating the tilting control will tilting an almost ruler-straight response curve, to a maximum steepness of 1dB/Oct. What sets it apart from all other tilting EQ designs is that we designed it around a highly linear 1dB/oct slope filter, so that rotating the tilting control will tilting an almost ruler-straight response curve, to a maximum steepness of 1dB/Oct. So what we acheive in the 1dB/Oct tilting function is 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 is apparent. In total, it allows quite some correction without sounding "Eq'ed". And because you'd occasionally want to correct outer ends of spectrum, we have added a gentle Baxandall tone control, shelving lows and highs, wide-Q bell mid, each at three selectable frequencies, that we spent quite some time optimizing.

Gentleness and subtlety were main design targets here: Nothing anywhere near surgical: tilting and Highs at +/-4dB, mids at +/-2dB, and lows at +/-6.5dB.
