The GL2200 features a set of GROUP/AUX REVERSE (REV) switches, which can transpose the AUX
and GROUP controls in pairs. These switches are recessed to avoid accidental operation. Set using a
pointed object or a pen tip.
This feature allows you to set the operation of the console for Front Of House, Stage monitor or a
combination of both (Dual mode).
With the switches out, the groups operate in the conventional manner, channel grouping using the
channel routing switches.
When the REVERSE switches are pressed in, the group busses are routed to the AUX send masters
and the aux busses are routed to the GROUPS (Aux 1 to Group 1, etc). Aux 5 & 6 are routed to L-R
faders respectively.
This configuration allows the user to control up to six monitor mix levels on faders. Outputs are on
balanced XLRs for long cable runs and a signal processor (equaliser, compressor, limiter, etc.) can be
inserted into the signal path using the group and left/right INSERT jacks.
The L-R and group busses are still operational but are now routed to the aux master controls and can
be used for additional monitor or effect sends.
It is advisable to study the GL2200 block diagram to fully understand this flexible routing arrangement.
