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.
