GQX Equalizers
GQX equalizers are a second generation design including many refinements on the original
GQ models. Lower noise and distortion, greater accuracy, and additional output options are
the result. We continue using “Q” enhanced Wein bridge filters and interleaved summing for
constant “Q”, low ripple, and minimum filter interaction. A servo-balanced output stage
simulates a true transformer output to allow interfacing with virtually any type of load.
Connectors & Cables
Your GQX series equalizer is provided with three different connector types:
1. 1/4 inch stereo phone jacks (TRS)
2. Three pin XLR type connectors
3. Euroblock screw terminal connectors
These connectors will allow interfacing to most professional audio products. Inputs as well
as servo-balanced outputs can be used balanced or unbalanced. When possible, balanced
connections are recommend between all components in your system, as this eliminates
ground-loop induced hum and noise.
Unbalanced Connections and Grounding
If you must use unbalanced connectors, the negative lead of the connector should be tied to
the ground lead. Using unbalanced connections could result in chassis ground-loop noise.
Altering the signal/chassis ground relationship in equipment connected to your GQX unit
may eliminate the noise.
