GQX-3102 Front Panel

Power LED – Displays power on or off.

Equalization - The individual equalization

faders adjust the gain or loss at each filter

frequency. There are 31 of these faders per

channel on the GQX-3102. By adjusting a

combination of faders, an overall frequency

response can be developed and the physical

position of the faders will give an approximate

visual indication of this response.

Gain - The gain control adjusts the overall gain

of the equalizer when the EQ switch is "in". It is

generally used to compensate for level

changes due to the equalization process, but

can also adjust overall system level and gain

structure. Overall gain with this control is from

+6dB to -∞.

Level Meters - On the GQX-3102, a 10-

segment, two color LED level meter indicates

the output level of the equalizer. A Clip

indicator LED illuminates when any point in the

GQX-3102 Rear Panel

Inputs - For unbalanced inputs, the signal

should be on the + connection and the -

connection tied to ground. A mono 1/4" plug

used as an unbalanced connection will

automatically be grounded. When using a

stereo plug, XLR connector, or euroblock for an

unbalanced signal, the (-) input connection

MUST be tied to ground.

Operator Manual – GQX-3102 Equalizer

equalizer signal path reaches a level within 3dB

of clipping.

Range Switch - This switch selects the

operating range of the individual equalization

faders between 15dB and 6dB. The 15dB

settings should be used when this much

equalization is needed. The 6dB setting allows

finer resolution on the fader settings.

EQ Bypass Switch - This switches the Graphic

Equalization and gain adjustments, allowing the

effect of any equalization to be compared to a

"flat" response. This switch does not defeat the

High-pass filter.

High-Pass Filter - The high-pass filter can be

used to supplement the frequency response

achieved by the bandpass filters. Its function is

to "roll off" the response below a given

frequency eliminating subsonic interference like

wind noise or floor rumble. This frequency is

adjustable between 14Hz and 280Hz.

Ashly Servo-Balanced Output - This output

circuit is an active output which maintains a

constant output level between the (+) and (-)

output terminals, regardless of either terminal

being connected to ground. This servo-

balanced output provides an unchanged signal

without regard to ground.
