Test ARC on an HDMI source (ARC Rx)

The procedures below describe how to use the 980 to emulate an ARC Tx device (HDMI sink). The 980 can use
audio from its internal source or you can feed an external SPDIF source into the 980 and have the 980 inject the
SPDIF audio onto the Audio Return Channel on its HDMI Rx port. The ability to emulate an ARC Tx device enables
you to determine if your HDMI source device (typically an A/V receiver) can properly handle an audio return
channel stream. Refer to the diagram below for a depiction of the general test setup.
To test the ARC handling by an HDMI source (ARC Rx):
1. Connect an HDMI 1.4a cable from the HDMI 1.4a A/V receiver to the 980 Rx port.
2. Determine the HEAC mode for ARC that you wish to test with and then activate that mode by clicking on the
appropriate activation button. For example if you wish to test ARC in the Single Mode you would select the
appropriate button in the RX HEAC Control – HEAC Mode subpanel as shown below.
3. Determine what SPDIF source you wish to use: 1) from the SPDIF source on the 980, or 2) from an external
SPDIF source. Select the appropriate activation button in the ARC Source subpanel.
4. When using the 980's internal SPDIF source, select the appropriate button in the RX HEAC Control – ARC
Source subpanel as shown below.
