AR2412 Panel Layout
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 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 or Qu mixer.
The sockets are numbered 1-24. On GLD, any
input can be patched to any channel at the
console. On Qu, sockets are mapped one-to-one
to input channels.
Output sockets 12 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.
