Congratulations on purchasing the EQ™ 31FX! With its introduction, Peavey engineers have taken graphic equalizers to the next level. The EQ™ 31FX offers 31 bands of 1/3 octave filters featuring superior constant “Q” devices. LED indicators are located in the slider of the frequency bands to identify the presence of a high energy signal (usually feedback). This sophisticated feed- back detector system will allow you to quickly identify and remove feedback. It works like this: When the feedback detection circuit detects the frequency band with the most energy, it causes the LED in the slider of the associated frequency band to illuminate. By moving the fader downward for that band, the likelihood of feedback is reduced/eliminated. Most use the EQ 31FX in one of two ways:

1.To catch and reduce/eliminate feedback “on-the-fly” during a performance. 2. To determine frequency bands that are susceptible to feedback BEFORE the performance, and eliminating them in advance.

After the system is set up, bring up the microphone levels slowly. As they start to feed back, note the LED activity on the EQ 31FX feedback bands. Move the faders to decrease the “identified” bands. Now you have eliminated a high percentage of potential feedback problems, before the per- formance even begins! Note: It is not uncommon for feedback to be active over several frequency bands. Also, go easy when making fader adjustments since extreme movements will affect your per- formance and be counterproductive.

OPERATION NOTE

This equalizer is designed to provide room equalization, feedback control and system tone control. No amount of equalization will correct an acoustically bad room/mic/speaker arrangement or completely correct the response of a poor loudspeaker. Always begin with all sliders in the “0” position and avoid excessively cutting large segments of the audio passband, which would limit the system’s dynamic range. Exercise caution when attempting to boost equalization below cut-off of the speaker system. Typical sound reinforcement enclosures are not designed for 20 Hz performance and transducer damage could result.

FRONT PANEL FEATURES:

BYPASS SWITCH (1)

In Bypass mode (switch in), the input signal is routed directly to the output and is unaffected by all front panel controls except the low and high cut filters.

BYPASS LED (2)

This LED will illuminate when the Bypass switch is in the “in” position, indicating that the EQ and
