Mixer Operation
1�
Ensure all source equipment is turned on and operational. If
any optional wireless microphone systems are included, refer
Wireless Mic System Operation (p�11)
.
2�
For each channel (input source) in use, verify the green LED is
illuminated, and then turn up the knob until the red LED starts
to light, and then turn it down by one half to one full number
(
Note:
For each
MIC
input, depress the
LOW CUT
button as
needed to help increase speech intelligibility.
3�
Adjust the
OUT
volume level(s) to achieve the final output
(
). If the red LED(s) illuminate, decrease the level(s).
Remember:
Bad input = bad output. No adjustment on the mixer
can make a poor source sound better. For best results, be sure
to use high-quality audio files from your MP3 player or laptop,
and set the device to near full volume.
Whenever red LEDs are illuminated on the mixer, this is generally
a sign that input settings need adjustment.
PROLONGED OVERLOAD OUTPUT SIGNAL WILL DAMAGE THE AUDIO SYSTEM!
DIP Switch Settings
1� DUCKER ON/OFF
ON
(default) = When audio is sensed above a
threshold at MIC 1 and/or MIC 2 inputs, all other
inputs will be reduced to the level set by the
ducking level (switch 2). All other inputs will
gradually come back up to normal output level
automatically. Note that the CV Input will mute all
other inputs of mixer when signal is sensed above a
threshold regardless of this switch setting.
OFF
= Signal levels will not be automatically
reduced. Exception: the CV Input will mute all inputs.
2� DUCKING LEVEL
-15
(default) = When ducker is active, MIC 3 & 4, MIC/LINE 1 & 2, RCA 1 & 2, and
MUSIC inputs will be reduced by 15dB.
-70
= When ducker is active, MIC 3 & 4, MIC/LINE 1 & 2, RCA 1 & 2, and MUSIC inputs
will be muted
3� LIMIT 1 ON/OFF
ON
(default) = OUT 1 level will be limited to threshold (switch 4).
OFF
= OUT 1 level is not limited –
improper use of mixer with limiter off may damage
sound system!
4� LIMIT 1 THRESHOLD
+4
(default) = Allows OUT 1 to reach full line level output while protecting against
improper use and large signal spikes.
-6
= Reduces OUT 1 output level while providing the greatest protection against
improper use of the sound system.
5� LIMIT 2 ON/OFF
ON
(default) = OUT 2 level will be limited to threshold (switch 6).
