Group mixing features
After using the groups to create the desired sub-mixes, you typically want to
route and combine them with other signals or groups to create various output
mixes.These mixes can be your final house mix (L/R/Mono), a special mix for a
choir or vestibule area, or an additional feed tailored specifically for a video or
TV broadcast.
The two main methods for creating these additional mixes are:
1) The bus assignment switches (in conjunction with the Group Pan pot).
2) The Matrix Sends
The bus assignment switches take the post-fader/post-mute group signal and
routes it to the 3 main output buses.The feed to the L-R buses is always
through the Group Pan pot, the feed to the Mono bus does not depend on
that pan pot.
The Matrix Send pots allow the user to mix the post-fader/pot-mute group
signal with other groups plus the 3 main output mixes. If the PRE button is
pressed, the signal to the Matrix Send pots is pre-fader/pre-mute.This allows a
totally independent output mix to be created, the group fader level will not
affect the Matrix mix.The overall level of the entire Matrix mix is controlled by
the Matrix Masters, located at the far right of the Master section.
See Matrix section for further matrix information
NOTE:These following controls are ALWAYS fed from the Group audio signal,
the Fader-Flip switch does not affect their function.
Matrix Sends M1 & M2:Always fed from post-level/post-mute Group audio, or in
PRE position, from the post-insert/pre-level/pre-mute Group audio.
Group Pan: Always fed from the post-level/post-mute Group audio.
Bus Assignment Mono & L-R: Always fed from the post-level/post-mute Group
audio.
Creating additional mixes.
There is yet another way to create additional output mixes from the
Console, but it involves using an external mixer (an XR-20 or XRM would
be nice).The Groups have their own TRS output jacks that feed the post-
fader/post-mute group audio to the outside world.These group outputs can
be fed into an external mixer where they can be combined into as many
outputs as the external mixer is capable of providing. In effect, you are using
the external mixer to create additional “Matrix mixes”. Internally, you were
limited to the 2 Matrix sends (M1 and M2), but externally, you no longer
have this limit.The main difference is the feed to the matrix sends: internally,
you could choose Pre or Post, externally (using the Group-Out TRS jack)
you only have Post available. However, the Group Insert jack can be used to
derive a pre-fader signal for use with an external mixer if the Tip and Ring
contacts are tied together in the cable plug.This creates a “borrow-cable”
that allows the signal to still flow through the internal audio path of the
group, but allows the pre-fader, insert-send signal to be used as an external
feed.

Use the Matrix Sends
to create additional
mixes from the 11 main
buses (8 Groups, Left, Right
& Mono). These additional
mixes can be tailored to
suit a specific need, only
mix-in the signals you need,
or enhance the main-mix by
adding additional instru-
ments where needed.

If you need more than
the internal two-matrix
mix, you can use the out-
puts of the console to cre-
ate additional mixes exter-
nally. Use the 11 main
buses (8 Groups, Left, Right
& Mono), plus any of the 10
Auxes. These additional
mixes can be tailored to
suit a specific need; only
mix-in the signals you need,
or enhance the main-mix by
adding additional instru-
ments or vocals where
needed.
