MATRIX
MUTE GROUPs
let 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 effects,
muting a bank of radio mics during an instrumental number, muting stage mics during
scene changes etc....
The GL3300 includes 4 MUTE GROUPs controlled by a bank of 4 large illuminated
buttons between the Group and L-R faders. These latching switches may be selected
one at a time or together.
To set up a mute group, press one of the mute group selector switches
M1, M2, M3,
M4
on the input channels. Now press the corresponding mute group switch in the
master section. The mute group switch and the channel mute switch will illuminate and
the input channel signal will be muted.
An input channel can be a member of more than one mute group by simply pressing
another channel mute group selector switch.
Two matrix outputs
A
and
B
are provided. These are additional outputs on TRS jacks
controlled by 60mm smooth travel
FADERS
and with
AFL
monitoring to check the
post fader signal. The matrix mix is created from the 8 groups, L and R by adjusting
the
MTX
level controls. These signals are fed post their respective faders. Note that
in '
MONITOR MODE
' (
REVERSE
selected) the matrix is still fed from the groups
(now routed via the aux masters). External inputs to the matrix are available from
the adjacent stereo returns. The matrix outputs can be balanced by fitting the balance
option, refer to the Internal Link Options section in this user guide.
The matrix outputs satisfy a host of applications. Traditionally the matrix has been
used to feed additional speaker systems such as auditorium balcony speakers. These
are fed through delay units to compensate for acoustic delay due to the distance from
the main speakers. Here the balance of the mix may be slightly different from the
main speakers, for example vocal light to keep the vocals nearer the stage. Adjusting
the balance of the groups to the matrix achieves this. Another example is live sound
recording where the PA mix may be necessarily lacking in bass due to the acoustic
output of the orchestra or 'backline'. Compensate for this by recording from the
matrix with the group feeds adjusted for an even recording balance.
