Front Panel Description - Phonic MQ 3300 User Manual

FRONT PANEL DESCRIPTION

1.POWER switch with LED
Use this switch to turn the equalizer on and off.
Be sure to power-up before your power amplifier
is turned on to avoid loud transients which could
damage your speaker or annoy your audience.
2.HPF switch with LED
HPF stands for HIGH PASS FILTER which allows
the high frequencies to passthrough unchanged,
while severly attenuating (cutting) the very low
frequencies. Use this switch to protect your audio
system from damaging low-frequency transients
(loud thumps).The HPF LED will light up when
the high pass filter is working. MQ 3300 and MQ
3400 both have a 40Hz high pass filter, while MQ
3600 has a sweepable high pass filter from 20Hz
to 200Hz.
3.PEAK LED Indicators
The LED will light up if you set too high a level
for the output and overload happens. If this LED
blinks only briefly during the very loudest parts
of your program, there is no problem. But if it
stays on constantly for more than a couple of
seconds, you might have a distorting sound. If
this happens, simply turn down the level control
until this LED blinks only very briefly.
4.Individual boost/cut control
Moving these sliders upward boosts their labeled
frequency bands, and moving them downward
cuts (decrease) them. When moving these
controls past zero, you will feel the center-detent
(notch) in the control which makes it very easy to
find zero in a hurry, or even in the dark.

5.EQ RANGE selector switch
One of the reasons to use a graphic equalizer
is that the frequencies sliders themselves form
a graphic depiction of the frequency response
curve you have set. But if your setting is very
subtle, the graph becomes difficult to set and
see. If you encounter this difficulty, simply push
this RANGE selector switch.
6.EQ RANGE LED
This LED will change from red to green indicating
the maximum boost/cut range of the frequency
sliders has been reduced from 12dB to 6dB.
And you can make your adjustments, taking
advantage of the greater fader travel necessary
to get the same amount of boost or cut.
7.EQ IN/OUT switch with LED
This switch allows instant comparison of the
original sound with the equalizer sound. The
LED will go off when the equalizer is out of the
circuit.
8.LEVEL control
After setting your response curve by using the
individual frequency sliders, use this level control
to compensate for overall changes in the audio
signal level (volume).
