1.AC Mains Power Switch

This switch turns the EQM131 on or off. To prevent spikes or pops through the system, turn the EQ on with the system amplifiers off and turn the amps off before turning the EQ off.

2.Fader Boost/Cut 1/3 Octave Level Control

The 31 faders have 31mm of travel along with a center detent indicating the zero position. From the center point, moving the fader up will boost the signal at the indicated frequency, and moving the fader down will cut the signal at that frequency.

3.Range switch 6dB/12dB & Indicators

This switch allow you global gain selection of the 31 30mm faders. The selection is 6dB or 12dB of fader boost or cut. An indicator light will illuminate indicating the selection.

4.EQ Bypass Switch & Indicator

This switch allows you to bypass the EQ. When in Bypass mode a red LED will illuminate. Note: When selecting between bypass and active mode a level variance will occur if the master level is not set to match the incoming level.

5.Clip Indicator

This LED will illuminate if the input level exceeds +22dBM. If this occurs, turn down the signal coming into the EQ.

6.Variable Low Cut Filter

The variable 12dB per octave filter operates from 10Hz to 250Hz. The Low Cut filter allows frequencies above the selected filter to pass through the system. Note: This filter affects the 30mm filters.

7.Variable High Cut Filter

The variable 12dB per octave filter operates from 3kHz to 40kHz. The High Cut filter allows frequencies below the selected filter to pass through the system. Note: This filter affects the 30mm filters.

8.Level

This control is the master output level control. The potentiometer has a center detent which is unity gain when the system is wired for balanced operation. If the system is wired for unbalanced operation, it may be necessary to increase the gain to +6dB.
