Input sockets 24 balanced XLR inputs for
microphone and line level sources. The preamps
are built into the AR2412 rack and their Gain,
Pad and 48V phantom power is remote controlled
from the GLD mixer via the dSNAKE link. The
output of the analogue preamps are converted to
digital format and transported via dSNAKE to be
processed and mixed at the GLD mixer.

The sockets are numbered 1-24. Any input can
be patched to any channel using the
I/O or
Preamp screens. The default is one-to-one
mapping of the input sockets 1-24 to channels 1-
24.

Output sockets 12 balanced XLR outputs
operating at nominal +4dBu line level. Any GLD
signal can be patched to any socket using the
console
I/O screen. The default Template Shows
provide a logical mapping of these sockets to get
you started. 
