Congratulations on purchasing the Q
™
231FX! Peavey engineers have taken graphic equalizers to the next
level with its introduction. The Q
™
231FX is designed to provide refined control over any sound reinforce-
ment or studio application. We trust that you are eager to place this unit into YOUR system ASAP.
The Q231FX offers dual 31-band graphic equalization with 1/3 octave filters featuring superior constant “Q”
devices. Each channel has balanced inputs/outputs and Peavey’s exclusive FLS

Feedback Locating
System that consists of LED indicators located above the frequency bands to identify the presence of a high
energy signal (usually feedback). This sophisticated feedback 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 above the associated frequency band to illuminate. By moving
the fader downward for that band, the likelihood of feedback is reduced/eliminated.
Most people use the Q231FX in two ways:
1. To catch and reduce/eliminate feedback “on-the-fly” during a performance, and
2. To determine frequency bands that are susceptible to feedback BEFORE the performance, eliminating
them in advance. How do you do this? After the system is set up, slowly bring up the microphone levels. As
they start to feedback, note the LED activity on the Q231FX feedback bands. Move the faders to decrease
the “identified” bands. Now you have eliminated a high percentage of potential feedback problems before
the performance even begins!
NOTE: It is common for feedback to be active over several frequency bands. Also, go easy when making
fader adjustments since extreme movements will affect your performance and be counter productive. If any
operational questions come up, be sure and contact our Customer Service department at (601) 483-5365.
Thanks for supporting Peavey!
OPERATION NOTE
For best results, set the mixer levels high enough to cause the Feedback Locating System LEDs to become
active (0 dBV, 1 V RMS). This may require you to turn down the power amp to maintain an acceptable
volume level.
