Operation Manual

28
Before starting, decide how you want to use your mute groups. Choose
the operating mode for single or multiple groups. Refer also to the section
on MUTE SAFES for details on how to prevent selected channels from
being operated by the groups.
SELECT THE OPERATING MODE
# Set the underpanel MODE switch up or down :
Up = SINGLE
Recall only one group at a time. The switches are interlocked
- pressing another switch cancels the operation of the
previous. Typically this is used when the groups recall mute
settings for different bands or scenes.
Down = MULTI
Recall more than one group at a time. Typically this is used
when the groups mute combinations of instruments, mics or
effects.
TO DISABLE THE MUTE GROUPS
# Set the underpanel DISABLE switch :
Up = Mute groups available
Down = Mute groups turned off
MUTE GROUPS
A mute group lets you mute a selected combination of channels with a single key press.
Applications include muting unused channels when mixing different bands, muting all
channels except 2-track playback during intermission, muting all effects, muting a bank
of radio mics during an instrumental number, muting stage mics during scene changes,
and so on...
The GL4000 includes 8 mute groups controlled by a bank of large buttons to the right
of the master faders. These may be selected one at a time or together depending on
the mode of operation preferred. Groups may be easily programmed and edited off-line
by the user without affecting the console mutes, essential when making changes during
a live show. A preview function lets you quickly view the settings of individual groups.
Selected channels may be made 'safe' so that they are not affected by the mute groups,
necessary when channel assignments are changed during a show. Group settings can
be archived via MIDI. If preferred, the system may be disabled when mute groups are
not needed so preventing accidental operation.
