MQX-2310 & MQX-2150 Front Panels

Equalization - The individual equalization

faders adjust the gain or loss at each filter

frequency. There are 31 of these faders per

channel on the 2310, and 15 faders per

channel on the 1250. 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 - .

Signal Present LED - A green LED indicates

when input signal to the equalizer is above -

20dBu. EQ or Gain settings have no effect on

this indicator, as it only tells you the level of

signal applied to the equalizer.

Clip Indicator LED - The red Clip LED turns on

when any signal within the audio path exceeds

+19dBu. Clipping can be detected at the input

stage, gain stage, or at the equalizer output.

Operator Manual – MQX Series Equalizers

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

equalization is needed. The ±6dB setting

allows finer resolution on the fader settings.

EQ In/Out 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. It's function is

to "roll off" low end response to eliminate

subsonic interference like wind noise, floor

rumble, and boomy microphone pops. The

high-pass frequency on the 31-band models is

fixed at 40Hz with an 18dB/octave slope. The

MQX-2150 has an internally switched 20Hz

high-pass filter which can be disabled by a

qualified service technician.
