Additional Inputs & Outputs

26. MON SEND

Stage monitors allow the talented musicians in the band to hear themselves clearly on stage. This can be a good thing! The monitor mix may be carefully adjusted in level using the aux mon controls [16]. These tap a portion of each channel's signal to provide a 1/4" TRS output here to feed external stage monitors. These could either be passive stage monitors powered by an external amplifier, or powered stage monitors with their own built-in amplifier.

The monitor signal is the sum (mix) of all the channels whose aux mon control is set to more than minimum. If they want “more me and less Brian,” you may turn up their channel's aux mon control, and turn down Brian's. Of course, with two monitor buses and two monitor outputs, anyone who wants “more Brian” can have their own monitor mix.

The overall output level may be adjusted with the aux master mon knob [42] and mon 1 may have its EQ tweaked with the graphic EQ [37] if the main mix/mon 1 switch [38] is pressed in. Alternatively, you could add an external graphic EQ between this output and your powered monitors. This will allow you to adjust the EQ, and minimize the chance of feedback from nearby microphones.

The monitor output is not affected by the main mix fader [56] or the channel faders [23]. This allows you to set up the monitor mix and level just right, and not have it change when a channel fader or the main mix fader is adjusted. This is known as “pre-fader.”

27. FX SEND

This 1/4" TRS line-level output may be used to feed an external effects processor (FX), such as a nice sound effect, or delay unit. The output from this jack is an exact copy of what goes into the internal FX processor, being the careful mix of all channels whose aux FX control [17] is turned to more than minimum.

(The processed output of the internal FX does not come out of this output, but is added internally to the main mix or monitor mix.)

The overall output level may be adjusted with the aux master FX knob [42]. (This knob also affects the level going into the internal FX.)

The output is “post-fader,” so any changes to the channel faders [23] will also affect the level going to the external processor.

The processed output from the effects processor is usually returned to the aux returns [29] or a spare channel, and you may carefully mix the original unprocessed channel (dry) and the processed channel (wet). Altering the original channel fader increases both the wet and dry signals and keeps them at the same delicate ratio. For example, the reverb remains at the same level relative to the original.
