7. Left/Right Maui Outs: XLR & 1/4"
The male XLR connectors provide a balanced
line-level signal that represents the end of the mixer
chain, where the fully mixed stereo signal enters the
real world. Connect these to the left or right inputs of
your main power amplifiers, powered speakers, or serial
effects processor (like a graphic equalizer or
compressor/limiter). The XLR outputs are 6dB
hotter than the TRS outputs.
The 1/4" TRS output connectors provide balanced or
unbalanced line-level signals. Connect these to the next
device in thc signal chain like an external processor
(compressor/limiter), or directly to the inputs of the
main amplifier. These are the same signal that appears
at the XLR main outputs, hut 6 dB lower when the XLR
is used balanced.
8.
Main Inserts
These 1/4' TRS jacks are for connecting serial effects
such as compressors, equalizers, deessers, or litters.
The insert point is after the mix amps, but before the
main mix fader [75]. Refer to the description of the
channel insert on the previous page to see how to
make this connection.
9. Mono Out
The male XLR connector [balanced] and 1 4" TRS
output connector (balanced or unbalanced] provide
a line I vel signal that is a combination of the left and
right n am ft [] signals (L+R). You may use this for
a eparate
mix
that does not require a stereo feed, or
to soup y test the monaural compatibility of the stereo
mix Again, when used balanced, the XLR signal isO dB
higher than hat from the TRS jack.
0. Mono Out Level Contra
This is a separate level control for the mono out (9].
It comes after the main mix fader 175] so turning the
main mix fader up and down does affect the mono out
signal. With this control turned all the way up you will
have 6 dB of extra gain at the mono out.
Ii. Group Outs 1-4
These 1/4" TRS jacks pro' ide balanced or unbalanced
line-level signals and are typically patched to the
inputs of a multitrack deck, or to secondary amplifiers
in a complex installation
12. Group Inserts
These
1/4" TRS
jacks are for connecting serial effects
such as compressors, equalizers. de-essers, or filters.
The insert point is after the mix amps, but before the
group send masters [74) (and after the built-in stereo
compressor [72]). Refer to the description of the
channel insert [3] on the previous pige to see ho~ to
make this connection.
13.Aux
Sends 1-6
These 1/4" TRS connectors allo~ you to send balanced
or unbalanced line-level outputs to external effects
devices, headphone amplifiers, or stage monitors. These
could either be passive stage monitors powered by an
external amplifier, or powered stage monitors with built-
in power amplifiers. AlL six auxes are independent of
each other, so you can run up to six separate aux mixes.
Aux sends 3-4 may either be pre or post fader,
depending on the position of the pre/post switches [28].
For stage monitor work, use pre, so the stage monitors
do not increase in volume when the channel level is
adjusted. Imagine how upsetting that can be to big hairy
drummers, This allows you to set up the monitor mix
and levels just right, and not have it change every time
a channel level is adjusted.
For external processors, use post. In this way, the
feed to external processors will vary with the channel
level, so the level of any returned effect (like an echo)
will also change if the channel level is changed, keeping
them in the same ratio (wet/dry).
