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 spe-
cial mix for a choir or vestibule area, or an additional feed tailored specifi-
cally 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 - These controls allow the user to mix the post-fader/post-mute
group signal with other groups and/or the 3 main output mixes. If the PRE button is
pressed, the signal to the Matrix Sends is pre-fader/pre-mute. This allows a totally inde-
pendent output mix to be created, and 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. Matrix Sends are always fed from post-level/post-
mute Group audio, or in PRE position, from the post-insert/pre-level/pre-mute Group
audio.
See Matrix section for further matrix information
NOTE: These following controls are ALWAYS fed from the Group audio signal, the Fader-
Reverse switch does not affect their function.
Matrix Sends M1 and 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 and 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 out-
side 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 are
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.
If you need more than the internal two-matrix mix,
you can use the outputs of the console to create
additional mixes externally. Use the 11 main buses (8
Groups, Left, Right and 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 instruments or vocals
where needed. ®
