ARC (Audio Return Channel) Mode
To enable/disable ARC, press the button with the “paperclip” marking. The ARC led will illuminate blue
when ARC is enabled; no illumination means ARC is disabled. ARC mode on the EVRXDSC receiver is only
compatible with the Evolution PRO EVMX44PRO and EVMX88PRO matrix units.
The EVRXDSC receiver can send audio back downstream with ARC capability at the matrix unit and broken out
via digital optical audio outputs, with two options:
1. Connection with an ARC capable display using the display’s HDMI ARC port; ensure the ARC functionality
is active within the display’s settings
2. Connection with a display that does not have ARC functionality, however has a digital optical audio
breakout. (If the display does not feature a digital optical audio breakout, an HDMI audio extractor can be
added, visit www.vanco1.com for audio extraction solutions)
