S/PDIF

The S/PDIF port is used for two audio options, ARC or matrix source audio de-embedding. When using one, the other is disabled. By default the matrix comes with ARC turned off on all ports, this enables the S/PDIF to de-embed audio from the matrix source. To switch between ARC and matrix source audio, ARC must be turned on or off. Enable or disable ARC through RS-232 (see page 18) or front panel (see below).
