Balanced Inputs
Balanced professional inputs are provided via dual XLR-3 connectors or the
single RJ45 connector. The two connector types are wired in parallel and
each can take unbalanced signals by connecting the non-phase of each
channel to signal ground (screen). The inputs can be configured as either
stereo, with six stereo outputs, or as mono with twelve outputs.
The XLR-3 pin inputs have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-Phase
