Front Panel Function:
a. Power Switch
This is the AC power switch, press it down, the blue LED bright, it means the
machine has switched on.
b. Increase/Reduce fader
Of the 31 bands, each attenuator controls each band increase/reduce bypass filter
signal level, the maximum increase/reduce of its central frequency is
±
15dB,
when signal level has adjusted, the curve of the attenuator adjusted is the EQ
frequency response. Please take note that when adjusting, the level between
neighboring frequency points can be widely discrepancy, usually it doesn
exceed 3dB.
c. Feedback frequency indication LED
It provides 31 standard frequency display indication, when any frequency display
of the sound field produces feedback, its feedback LED can accurately show it to
you, and you can according to practical situation to attenuate frequency by far to
non-feedback.
d. Output signal VU meter
This meter is LED multi-step, respectively green LED show -20, -15, -10, 0, +10dB,
orange LED shows +15dB and red LED shows +20dB, the accurate level
indication makes you can monitor the output signal level at anytime and match
with back-step equipment.
e. Feedback display sensitivity
When several feedback frequency levels are closed to each other, and lead two or
several LED bright at the same time or the feedback level is low and the LED dark.
You can use this button to adjust threshold level of feedback indication, so that you
can see clearly of which frequency makes feedback and take relevant measures
to restrain.
f. Filter button and indicator
This knob controls connection (j)
“
High-pass
”
and (i)
“
Low-pass
”
of the filter,
press it down, connecting input circuit to the filter.
g. Bypass button and indicator
This knob controls the machine connection and bypass. It is convenient for the
soundman to compare signal between before and after equalizing. Press it down,
circuit bypass, signal directly from input channel through relay to output channel.
h. Output clip LED
This LED indicates that whether output signal is clipped or not. When it twinkles
once in a while, it indicates signal sometimes clip, but when it frequently twinkles,
it means signal badly clipped, and you should reduce input by far to the LED not
twinkling.
