MASTER SECTION FEATURES
Before you read this chapter,
you might want to look at the
rather lovely channel strip fea-
tures on the previous page.
27. STEREO GRAPHIC EQ
This equalizer is used to shape
the frequency spectrum of the
main mix or monitor mix. It is
the last thing in the signal chain
before the MAIN MIX (34) faders
and the MAIN OUT (5) jacks.
Each EQ slider controls a dif-
ferent section of the audio
frequency range. Moving a slider
up or down will boost or cut the
output levels of signals around
the slider’s center frequency. By
setting all the EQ sliders to zero
(center) you’ll effectively remove
it from the signal path.
The following steps show how
the equalizer can be used to
reduce feedback:
1. Set the EQ sliders to zero
(center) while the band
plays on.
2. Set the channel GAIN (16)
levels, using the LEVEL
SET LED (17) and adjust
the channel faders for a
nice mix.
3. Slowly turn up the MAIN
MIX (34) faders until feed-
back just begins to occur.
BE CAREFUL! Feedback
can occur quickly and be-
come very LOUD, very fast.
4. Cut the appropriate EQ slider
until the feedback stops.
Here are some general sugges-
tions on using the EQ:
For better vocal sound, set the
250, and 12K sliders to +5.
Note: Make sure the singer
is within 3 to 6 inches of the
microphone. No amount of
EQ can save a wandering
minstrel.
For more presence, set the 3.5K
slider to +5.
To warm up the overall sound,
set the 1K slider to –5.
REMEMBER, LESS IS BETTER.
