Gyraf Audio Gyratec XIV Stereo Parallel-Passive Equalizer

Gyraf Audio Gyratec XIV Stereo Parallel-Passive Equalizer is a true tube, all passive, stereo equalizer. It consists of five bands - each with 11 switchable frequencies, variable "Q", and boost/cut selection.

Gyraf Audio Gyratec XIV Stereo Parallel-Passive Equalizer Details

Gyraf Audio Gyratec XIV Stereo Parallel-Passive Equalizer is a true tube, all passive, stereo equalizer. It consists of five bands - each with 11 switchable frequencies, variable "Q", and boost/cut selection. It also has an output level trim, and a "hard" relay bypass control.


The two channels are linked - controlled with one set of knobs. The "Q"s (filter sharpnes'es) are rather low when boosting, but higher at cut - approaching a notch on extreme cut settings. This is both a side-effect of the applied passive technology - as well as quite desireable in situations where sound integrity is the paramount factor.


The frequencies are selected with special attention to controlability of the midrange area, and with half a frequency-range overlap to the adjacent bands.


Gyraf Audio Gyratec XIV Stereo Parallel-Passive Equalizer is a very extended version of the classic passive inductor/capacitor type filters, the most famous being the "Pultec" units. Even though the classic versions are usefull tools in most situations, they are somewhat limited in use due to their simple construction.


Gyraf Audio Gyratec XIV Stereo Parallel-Passive Equalizer has a truely passive design - based on switching a set of inductors and capacitors in and out of circuit - combined with an E88CC (6DJ8) tube-based makeup gain/output stage. Not a single IC's or semiconductor in the signal path - this is a real tube unit. The inputs and outputs are - off course - transformer balanced, for trouble-free interfacing to the outer world.
