37. PAN
For the mono channels (1 to 8) this control allows you
to adjust how much of the channel signal goes to the
left main mix, and how much goes to the right main mix.
It has no effect on the aux, as these are mono. In the
center position, the mono channel is split equally to the
left and right.
For the stereo channels (9/10 and 11/12), pan acts in
a similar way to a home stereo balance control.
If you have a stereo source and the mixer's stereo
inputs are already taken, connect the source's left out-
put into one mono channel, and the right into another.
Pan the fi rst one fully left, and the second channel fully
right, then the source will appear in the main mix in full
stereo.
38. MUTE switch and LED
The mute switch cuts the signal from the channel
from reaching the main mix bus and the aux busses. The
LED acts as a reminder of its on-ness.
The mute switches near the FX RTN 1 and FX RTN 2
faders will stop the signals from the internal effects (or
any external effects) from reaching the main mix, or
monitor 1 or monitor 2.
39. –20, 0, +10, OL CHANNEL METER LEDs
The OL (overload) LED will come on when the chan-
nel’s input signal is too high. This should be avoided, as
distortion will occur.
If the OL LED is coming on regularly, check that the
gain control [23] is set correctly for your input device,
and that the channel EQ [27–32] is not set with too
much boost.
The –20, 0, and +10 LEDs show the channel signal
strength.
40. CHANNEL FADER
The channel faders adjust the level of each channel
onto the main mix. The “U” mark indicates unity gain,
meaning no increase or decrease of signal level. All the
way up provides an additional 10 dB, should you need
to boost a section of a song. If you fi nd that the overall
level is too quiet or too loud with the level near unity,
check that the gain control [23] is set correctly.
41. SOLO
Whenever a solo switch is engaged, you will only hear
the soloed channel(s) in the headphones. This gives you
the opportunity to audition the channels before they are
added to the main mix.
You can also use solo to set the gain of each channel
correctly. When a channel is soled, you can adjust the
channel gain [23] until your input source reaches the
level of the 0 dB LED of the main meters [48].
Solo signals reaching the headphones are not
affected by the channel faders or main fader,
therefore turn down the phones level [19]
rst, as soloed channels may be loud.
The rude solo light [49] will turn on as a reminder
that what you are listening to in the headphones is just
the soloed channel(s).
For stereo channels, the mono sum of the left and
right are heard in the headphones and the level seen on
the left meter.
The output from the FX processors can also be soled
and auditioned, as can the output to monitor 1 and
monitor 2.
