1.
Power – Switches the unit power on or off.
2.
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.
3.
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 - .
4.
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.

5.
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.
6.
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.
7.
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.
