Channel 1 and 2 are identical.
1.
This fader is used to boost or cut a dedicated frequency.
a. Moving the fader upward will boost frequency upto +12dB.
b. Moving the fader downward will cut frequency upto -12dB.
.

Boost/Cut fader:
2.
: This switch is used to cut/attenuate signals below 63Hz. The low cut is activated when switch is in
''pressed'' position.
3.
: This LED lights up when the low cut mode is in operation.
4.
: This switch is used to activate the EQ IN/Bypass mode. When switch is in ''Released'' position,
EQ IN mode is active and if the switch is in ''Pressed'' position, EQ is ''Bypassed''.
5.
: This LED lights up when EQ is by passed.
6
: This fader sets the signal level to the Equalizer.
: It will show the signal level. Red led indicates the clipping of the signal.
8.
: This LED lights up when there will be feedback generation.
9.
: Feedback indication LED brightness can be controlled by display fader.

How to use Feedback Function:
•
If there is feedback in the system, the feedback detection LEDs indicate frequency ranges with the highest energy levels.
If you keep an eye on the LEDs while you play back your music (or during the sound check before a show), you can
easily identify those frequencies causing feedback. Similarly, increased signal levels on individual frequency bands
indicate a higher likelihood that feedback may occur.
•
If feedback occures, pull down the respective faders whose LEDs are lit until the feedback subsides. Repeat this procedure
to eliminate other possible feedback frequencies.
