Operator Manual
Uses of the configurable audio connections
The standard XL8 Live Performance System has a total configurable audio channel
count (on the DL451 I/O units) of between 120 and 240, depending on the mix of
analogue and digital I/O (excluding the non-configurable 96 mic inputs on the DL431
mic splitter).
Typically, the allocation would be:
• 16-off mic/line auxiliary inputs (giving a total of 112 mic inputs as standard).
• 32-off aux/group bus outputs.
• 16-off matrix (main) outputs.
• 1-off stereo main output.
• 1-off mono main output.
• 2-off stereo local monitor outputs.
This gives a total of 71 audio connections, leaving a further 169 (with everything
digital) or 49 (with everything analogue) audio connections. These can be used for
insert sends, insert returns, direct outputs, bus direct inputs and side chain
connections.
