FRONT PANEL

1. MIC/LINE MONO INPUTS – Connect a microphone or line level instrument
to these inputs using standard XLR or ¼" cable.
2. MIC/LINE STEREO INPUTS-
organized in stereo pairs. If you connect only the left jack, the input will
operate in mono mode, (the mono signal will appear on both input
channels). You can use these inputs with a stereo keyboard, drum machine,
etc.
3. LEVEL – Adjusts the channel audio level (pre-fader and pre-EQ gain).
Adjust this so that the PEAK LED rarely lights up during the loudest parts of
the song.
4. CHANNEL BAL – Adjusts the channel's position in the stereo field.
5. AUX 1 Pre – This adjusts the prefader signal sent to the Monitor output and
is controllable using the Monitor Level knob. To use an external effects rack
unit, compressor, etc. with the mixer, you can use a Y-cable to connect the
AUX out to the input of your external device, and then connect the outputs of the device to the Stereo Return of
the amp.
6. AUX 2/FX Post- This adjusts the post fader signal which is sent through the
AUX OUT and is controllable with the DSP knobs to route the signal to the
MON or MAIN outputs. You can use a 1/4" TRS cable to connect the AUX
OUT to the input of an external amplifier or active monitor to create a
custom mix for onstage musicians with the mixer's internal effects.
7-9. EQUALIZATION- You have three EQ controls for each mono and stereo
input channel each providing +/-15 dB of boost and cut. The signal will be
unaffected when the controls on the center position. You may use an
external equalizer to make up a mix properly but a master equalizer will not
have effect on a single channel and you may overload the signal easily.
Individual EQ will give you a much better control on single tracks.
7. HI EQ (TREBLE) – Adjusts the high (treble) frequencies of the channel.
8. MID EQ – Adjusts the mid-range frequencies of the channel.
9. LOW EQ (BASS) – Adjusts the low (bass) frequencies of the channel.
10. -20dB PAD- Pressing this button will attenuate the input signal by 20 dB.
This will give increased headroom and reduce the risk of distortion from
input signal peaks.

MASTER SECTION

11. STEREO GRAPHIC EQ: There are
each with 9 adjustable bands; one is for the MAIN
mix and the other is for the MONITOR mix. With the
faders you can boost or cut the selected frequency
by +/-15 dB at the indicated frequencies. When all
faders are at the center position, the equalizer is
disabled.
12. FEEDBACK TERMINATOR Button (MONITOR
mix) - This button activates the feedback detection in
the monitor signal path. Feedback will be identified at
a certain frequency when the corresponding fader
LED lights up. Feedback produces an unpleasant
speaker "howling" or "whistling". In order to eliminate
feedback, turn down the corresponding fader until
feedback disappears.
13. MONITOR LEVEL LED Display- This LED display
will show you the monitor output level. Make sure that the +10 LED only lights up
occasionally. The optimal level is between -10 and 0 on the LED. If only the -30 LED lights up
or does not come on, your S/N ratio will be degraded.
14. FEEDBACK TERMINATOR Button (MAIN mix)- This button activates the feedback
detection function in the Main mix signal path. Feedback will be identified at a certain
frequency when the corresponding fader LED lights up. Feedback produces an unpleasant
speaker "howling" or "whistling". In order to eliminate feedback, turn down the corresponding fader until
feedback disappears.
