Protected underpanel mode switches set the console architecture according to the required application, for example FOH
or stage monitor. Select these using a pointed object.
DIR OUT routes the channel direct out signal
through the aux 10 pre/post selector and
level control.
OUT REV swaps the matrix or LR2 output
jack with the related aux XLR and insert. The
control sections are not swapped. This can
provide matrix outputs on XLR with inserts, or
aux effects sends on jack as required.
TRIM ON routes the group output signal
through a pre/post fader selector and level
trim. This lets you record the groups
independent of the subgrouping to LR and M.
MTX TO AUX Links the matrix mix into the
aux mix to include aux sends from the groups,
LR and M. Used for effects from the groups,
and for quick monitor mixes.
GRP REV reverses the aux (small fader) and
group (main fader) control sections. Also
applies to LR. The outputs remain unaffected.
This mode is used for stage monitoring.
MONO MODE converts the mono output to
the monitor engineers listen wedge. M AFL
is disabled. The M mix still feeds the insert
and matrix.
