GQX-3102 Front Panel

Power – Switches the unit 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 3102, and 15 faders per

channel on the 1502. 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 on all models illuminates when

any point in the equalizer signal path reaches a

level within 3dB of clipping.

Operator Manual – GQX Series Equalizers

Range Switch - This switch selects the

operating range of the individual equalization

faders between 15dB and 6dB on the 3102.

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 on the

3102, and is fixed at 40Hz on the 1502.
