MODE SWITCHING

Set the underpanel mode switches for the intended console

operation. Some of these affect the way the connectors work. For

full details please refer to the BLOCK DIAGRAM.

 OUT REV underpanel mode switch - The Aux XLRs and

inserts can swap with the Matrix and LR2 output jacks for aux

(effects) sends on jacks if required. This also provides matrix and

LR2 outputs on XLRs with inserts for driving speaker systems.

 MONO MODE underpanel mode switch - The Mono output

becomes the engineers listen wedge monitor feed when the

console is operated in on-stage monitor mode. However, the Mono

insert remains with the mono mix.

 MIX/AUX REV underpanel mode switch - Note that while the

front panel control sections are swapped when the reverse mode

switches are pressed, the signals always appear at their related

connectors, ie. the connectors do not swap.
