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 first 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 find 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]

first, 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.
