The MUTE, AUX 9-10 and L-R-M Masters
MUTE MASTERS 1-4 Press to mute all the input channels
assigned to the mute group. Any combination of masters may be
active at any time. The red LED indicates that the master is active.
AUX 9-10 MASTER
Controls the master level of stereo Aux 9-10.
Up to +10dB boost is available above the normal 0dB position. Note
that this becomes the LR master in monitor mode.
REV mode switch Reverses Aux 9-10 rotary master with the L-R
faders, inserts and XLR outputs. Recessed to prevent accidental
operation. Use a pen or pointed object to set the position. In monitor
mode (switch pressed) the stereo aux is controlled by the main faders,
for example to provide a stereo in-ear monitor mix.
Note: LR always feeds the matrix and LR to M controls regardless of
mode. This means the LR mix can still perform a useful function when
the console is configured in monitor mode. The Aux mix is always
monitored by selecting the nearby monitor select AUX 9-10 switch.
AUX MUTE When pressed the stereo aux (LR) signal is turned off.
The red indicator lights when the channel is muted.
LR to M Dials the sum of L and R into the M mix to create a mono
output from the stereo mix. You can use this to create a starting point
for a fill or centre mix, and then add selected channels using their M
routing switches. This control always routes the LR signal to M
regardless of mode.
METERS 4 LED bar meters display the post-fade LRM master
signals (FOH mode), or aux 9-10 and engineer’s wedge signal
(monitor mode, REV pressed)
LR MASTERS Separate 100mm faders control the main mix L
and R output levels. They provide +10dB maximum boost. Each
master includes a 4 LED bar meter and a MUTE switch so that L and R
can be separately muted. This is also useful in monitor mode where
these masters carry the Aux 9-10 signals.
M MASTER A 100mm fader adjusts the level of the M mix. The
master is fully featured and includes a 4 LED bar meter and a MUTE
switch.
WEDGE mode switch This switch is recessed to protect it from
accidental operation during the show. Use a pointed object to set its
position.
FOH mode – In the up position (flush with the panel), the fader is the
master for the main M mix, typically used to feed a mono fill or C
(centre) mix.
Monitor mode - Press to create an engineer’s monitor listen wedge
feed from the AFL/PFL mix. It is common to use a wedge speaker of
the same type used on stage to listen to and check the various
monitor mixes being sent to the performers. Together with the
group/aux REV function, the GL2800 can be configured as a
compact yet fully featured monitor console.
