Operating Manual - MQX-2310, MQX-1310, and MQX-2150 Graphic Equalizer
5. CONTROLS
5.1 Equalization
The individual equalization faders adjust the
boost or cut at each filter frequency. There are 31 of
these faders per channel on the MQX-1310 and MQX-
2310 third octave models, and 15 faders per channel on
the MQX-2150 two-thirds octave model. 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.
5.2 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 allow the equalizer to adjust overall
system level and gain structure. Overall gain with this
control is from +6dB to -∞.
5.3 EQ In/Out Switch
This switches the Graphic Equalization and Gain
adjustments. This way, the effect of any equalization can
be compared to a “flat” response. This switch does not
defeat the High-pass filter.
5.4 Range Switch
This switch selects the operating range of the
individual equalization faders to either ±15dB or ±6dB.
The ±15dB settings should be used when much equaliza-
tion is needed. The ±6dB setting allows finer resolution
on the fader settings.
