Mute Snapshots
A mute snapshot lets you store the console mute on/off settings to be
recalled with a single key press. This is much like taking a 'snapshot'
of the console settings. Mute snapshots are used extensively for
scene or song changes during live performance. The advantage is
quick access to complex changes, a growing requirement with the
more sophisticated sound control specified today. Snapshot changes
can be linked to external sequencers and effects devices via MIDI for
sophisticated show control. Snapshots can be archived and recalled
via MIDI.
The GL4800 includes 128 mute snapshot memories. The snapshot
number is simply dialled up on the 3 segment display and its contents
recalled or overwritten with the current console settings. Recalling a
snapshot does not overwrite any active groups. Snapshot settings
may be checked before recall by using the preview function. Selected
channels may be made 'safe' so that they are not affected by snapshot
changes. If preferred, the system may be disabled when mute
snapshots are not needed.
Before starting, decide how you want to use the mute snapshot
system. Choose the recall operating mode with or without auto
increment. If you do not want to use the snapshot system you can
turn it off to prevent accidental operation. Refer also to the section on
MUTE SAFES for details on how to prevent selected channels from
being operated by the snapshots.
Select the Recall Mode
Set the underpanel MODE switch up or down :
Up = MANUAL INCREMENT
Scroll

The display automatically increments to the next
snapshot number each time RECALL is pressed. This
lets you step through your snapshots without having to

each time.
