Operator Manual – GQX Series Equalizers
GQX equalizers use "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.
GQX equalizers have with three different connector types:
1/4" inch stereo phone jacks
Three pin XLR type connectors
Euroblocks
These three connectors facilitate interfacing to most professional audio products. Inputs as
well as servo-balanced outputs can be used balanced or unbalanced
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 Connector
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.
