INTERNAL LINK OPTIONS
The console is set to satisfy most applications that should be encountered. However, the following internal
link options are offered to provide alternative settings for those applications that may require them. These
options involve resoldering of circuit board links and should only be carried out by competent technical
personnel. Further information is available in the GL3000 SERVICE MANUAL and from your agent.
MONO INPUT
1. Reconfigure each aux as required to be
permanently pre-fade or post-fade rather than
switched by the front panel PRE/POST switch.
2. Reconfigure the pre-fade sends to be post-
EQ / pre-mute, or pre-EQ / post-mute, instead
of the standard post-EQ / post-mute.
3. Disable +48V phantom power regardless
of panel switch position - remove link.
STEREO INPUT
1. Reconfigure each aux as required to be
permanently pre-fade or post-fade rather than
switched by the front panel PRE/POST switch.
2. Reconfigure the pre-fade sends to be post-
EQ / pre-mute, or pre-EQ / post-mute, instead
of the standard post-EQ / post-mute.
3. Disable +48V phantom power regardless
of panel switch position - remove link.
LEFT
1. Reconfigure the LR sum source (mono)
from post LR faders to pre faders.
2. Enable +48V phantom power to talkback
mic input - fit link.
GROUP
1. Fit Matrix out balance option for jack
output tip = hot, ring = cold. Remove two links and
plug in balance driver IC.
2. Reconfigure the feed to the optional VU
meterpod to follow the aux master rotary control
rather than the group fader - remove two resistors
and link two pairs of pads with a length of wire.
