Busses and Routing
Dual Purpose Front of House (FOH) and Monitor Applications
With its flexible routing and feature set, the Siena is happy to run both the front of house (FOH) mix and provide
monitor mixes for the artists on stage. In this dual purpose application, you will want to use some of the 16 mix
busses, as above, to generate your monitor feeds to the stage, while the remaining busses can be used to generate
audio sub groups.
The master controls for mix outputs 9-16 vary slightly from those for mix outputs 1-8. This is due to the fact that
mix bus outputs 9-16 may be routed, and panned, onto the stereo master bus. This makes mix busses 9-16 ideal
for use as group outputs as they may be output separately from the console and/or summed onto the stereo
master for a FOH mix. For these reasons, use mix busses 1-8 for auxiliary sends and 9-16 to create audio sub
groups when working in a hybrid FOH/Monitor application. A typical console layout may be as follows:
Mix Bus Format
1-2 stereo
3-7 mono
8 mono
9-16 stereo
Master Stereo stereo
input channels to create the FOH mix.
Group Outputs Typical Applications
Applications for groups vary, but include:
Sub mixes
Sub mixes are a common way of saving time (and possibly embarrassment) when using a large number of
microphones. For example: multiple microphones for Choirs, Drum Kits/Percussion, Orchestras, etc . . .
Typically, the sub mixes will probably be stereo so switch your chosen mix bus masters (e.g.9-16) into stereo mode
using the recessed stereo switches located beside the mix bus master faders.
Each input channel to be sub mixed should be routed to the mix bus send ONLY (i.e. not to the stereo master).
Remember to set both the level
between the channels in the sub mix.
The group masters (e.g. mix bus masters 9-16) should then be routed to the stereo master bus and panned L-R as
required. The sub mix is now set up.
The group master controls (mix bus masters) can now be used to control the overall level of the sub mix, mute the
sub mix output or solo the sub mix signal.
Note: muting the sub mix is not the same as muting the input channels, as other input channel sends remain
active. If channels within a sub mix are required to be muted, use the auto mute facility.
Master EQ/External Signal Processing
Often, it is either too expensive or undesirable to apply signal processing to each channel individually (for example:
compression on a whole choir, graphic eq on a number of microphones, etc...).
Set up a sub mix, as described above, to group similar signals together. Now the desired external processor can be
inserted into the group (mix bus master) insert send and return to apply processing to the sub mix.
Alternative Outputs
When mixing for a number of speakers in a venue, it may be necessary to generate separate mixes with different
levels or processing.
Route the input channels to the chosen mix bus sends, let's say mix busses 9 and 10 and adjust the channel send
and fader controls.
Make sure the groups (mix bus masters) are NOT routed to the stereo master output. The group outputs (e.g. mix
bus 9 and 10) should then be wired into the amplification feeds to the speaker systems.
You may now control the separate mixes using the channel mix sends and master mix bus controls.
