LR
THE CONSOLE LR AND LR2 OUTPUTS - In addition to the
main L and R outputs the GL4800 includes a secondary
pair of outputs called L2 and R2. These follow the LR mix and
may be selected either pre or post LR faders. As with the
matrix outputs an OUTPUT REVERSE switch is included on
each to swap the L(R)2 jack output with aux 9(10) XLR and to
switch in the insert. Use this when you need to drive long
cable runs, interface with standard XLR multicores and cables,
or insert EQs, delays or other signal processors.
Typical applications include:
Additional stereo speaker feeds - For zoning, dual speaker
systems and delay fills.
2-track Recording - For an independent feed from the LR
mix, pre or post fader. Can also be used as a simple stereo
broadcast feed.
L(R)2 MASTER - Selects and controls the L and R secondary
outputs. Adjust LEV to trim the output level to match the
connected equipment. ON switches the ou tput on or off. AFL
lets you monitor the signal post level trim, post insert but pre
ON switch.
METER - 12 segment, 3 colour peak reading meter for L and
R. Each meter can be switched to monitor either the main
fader signal (normally L and R) or the small fader signal
(normally aux 9 and 10). The switch does not affect the
optional VU meterpod which always follows the main fader
signals. The L and R meters can be switched using STEREO
PFL METER to be interrupted by stereo PFL when selected.
L(R) MASTER - The LR mix is normally controlled using the
100mm faders. If L(R) REV is pressed the main faders follow
the aux 9(10) signals and L(R) is available on the small faders.
As with the groups: automated MUTE, pre fade mix meters,
matrix sends and AFL are available.
L(R) TO MONO - The required amount of post fade L and R
signal may be added to the M mix using these controls. You
can create a quick mono output by mixing in equal amounts of
L and R signal. You can also use L and R as additional
subgroups to M.
