Inputs (1&2)
The XLR-3 input connectors can take balanced professional levels, or
unbalanced consumer levels by connecting the non-phase to the signal
ground and adjusting the rear panel input gain controls. The inputs can be
configured as either dual mono, input 1 routed to outputs 1-12 and input 2
routed to outputs 13-24, or mixed mono, inputs 1 and 2 mixed at a pre-set
level and routed to all 24 outputs. The XLR 3 pin input has the following
connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-Phase

Outputs (1 – 24)
The 25 way D-type outputs are electronically balanced, and can be wired
unbalanced (not recommended). Each output is individually buffered so
that a short circuit on one output will not affect the others. The outputs are
also protected from connection to POE (power over Ethernet) and phantom
power circuits. They have the following connections:
