FEATURES
1.
POWER IN – Use the included power
adapter to connect the mixer to a power
outlet. While the power is switched off,
plug the power supply into the mixer
first, then plug the power supply into a
power outlet.
2. POWER SWITCH – Turns the mixer on
and off. Turn on the mixer after all
input devices have been connected and
before you turn on amplifiers. Turn off
amplifiers before you turn off the mixer.
3. FOOTSWITCH – When a latching-style
footswitch is connected to this jack with
a 1/4" TRS cable, it can be pressed to
allow all channels to bypass the mixer's
internal effects processor.
4. MIC INPUT – Connect a microphone to
these inputs with an XLR cable.
5. LINE INPUT * – Connect line-level
devices to these inputs with 1/4" cables.
6. GAIN – Adjusts the channel audio level
(pre-fader and pre-EQ gain). Adjust
this so that the PEAK LED just barely
lights up during the loudest parts of the
song.
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. AUX SEND 1 MON – Adjusts the
channel audio (pre-EQ) level that is
sent to the AUX SEND output labeled
"1 MON." You can use this to create a
custom monitor mix for yourself or your musicians.
11. AUX SEND 2 FX – Adjusts the channel audio (post-EQ) level that is sent
to the mixer's internal effects processor. Turn this up for the channels that
you want internal effects applied to. You can use this to apply external
effects to individual channels.
12. CHANNEL PAN – Adjusts the (mono) channel's position in the stereo
field.
13. BALANCE (CH 5/6 & 7/8) – Adjusts the balance between Channels 5 and
6 and Channels 7 and 8.
14. PEAK LED – The LED will flash if the signal is clipping. If this happens,
decrease the setting of the GAIN knob or CHANNEL VOLUME knob.
15. CHANNEL VOLUME – Adjusts the audio level on the channel.
16. AUX RETURN INPUTS ** – You can connect the outputs of an external
device to these inputs with 1/4" mono cables. This is usually used for
outboard effects devices but can also be used like an extra input channel
for synthesizers, drum machines, etc. If your source is mono, plug it into
the left jack and it will be heard on both the left and right sides.
17. AUX SEND OUTPUTS ** – You can use a 1/4" TRS cable to connect the
AUX 1 MON output to the input of an external amplifier or active monitor to create a custom monitor mix for onstage
musicians. You can adjust this level with the AUX RETURN LEVEL knob labeled "TO AUX 1 MON." To use an external
effects rack unit, compressor, etc. with the mixer, you can use a Y-cable to connect the AUX 2 FX output to the input of
your external device, then connect the outputs of the device to the AUX RETURN INPUTS of the mixer.
18. 2-TRACK INPUTS – You may connect these inputs to the outputs of an external sound source using a standard stereo
RCA cable (sold separately). You can send this channel to the monitor mix (using the MAIN/2-TRACK switch) and/or
the main mix (using the 2-TRACK TO MAIN switch).
19. 2-TRACK OUTPUTS – You may connect these outputs to the inputs of an external recording device using a standard
stereo RCA cable (sold separately).
20. CTRL ROOM OUTPUTS – Use standard 1/4" cables to connect these outputs to your monitor or amplifier system. The
level of these outputs is controlled by the CTRL ROOM / PHONES knob.
21. MAIN MIX OUTPUTS – Use standard 1/4" cables to connect these outputs to the house speaker or amplifier system.
The level of these outputs is controlled by the MAIN VOLUME knob.
22. PHONES – Connect your 1/4" stereo headphones to this output. The CTRL ROOM / PHONES knob controls the
volume.
* When using LINE INPUTS 5/6, 7/8,
and the AUX RETURNS:
• If only the left channel is used, the
signal will be heard in both left and
right channels and the balance will
not be adjustable.
• If only the right channel is used, the
signal will be heard in the right
channel only.
** To use an external effects rack unit,
compressor, etc., use a Y-cable (1/4"
stereo to two 1/4" mono) to connect the
AUX SEND "2 FX" output to the left and
right inputs your external device.
Connect the outputs of your external
device to the left and right AUX
RETURN INPUTS.
