AR84 Panel Layout
Input sockets 8 balanced XLR inputs for
microphone and line level sources. The preamps
are built into the AR84 rack and their Gain, Pad
and 48V phantom power is remote controlled
from the mixer via the digital link. The output of
the analogue preamps are converted to digital
format and transported via a Cat5 cable to be
processed and mixed at the GLD or Qu mixer.
The sockets are not numbered. The GLD system
numbers these sockets as Local Exp Inputs 1-8
or dSNAKE Exp Inputs 1-8 depending on where
the AR84 is plugged into the system. Write-on
blocks are provided for you to label the sockets.
Output sockets 4 balanced XLR outputs
operating at nominal +4dBu line level. Any signal
can be patched to any socket using the GLD I/O
screen or Qu Setup / Output Patch / dSNAKE
menu. The mixer defaults to a logical mapping of
these sockets to get you started.
The sockets are not numbered. The GLD system
numbers these sockets as Local Exp Outputs 1-4
or dSNAKE Exp Outputs 1-4 depending on where

blocks are provided for you to label the sockets.
