If the RJ-45 connector is upside down compared to the one in FIG. 29, the yellow LED will be on the right and the green LED on
the left.
Audio Type Precedence
The connectors for bringing audio into the system on the Transmitters are as follows:
HDMI In connector – Embedded audio signal
Digital Audio In jack – Digital audio signal (S/PDIF); not available on the Wallplate TX and Decor Wallplate TX
Stereo Audio In jack – Analog stereo audio signal
The hierarchy for audio type precedence* is listed in the following table for the Transmitters:
* Audio precedence as specified in the table above is applicable when the AUDIN_FORMAT_AUTO command is set to ENABLE; this
precedence can be overridden by SEND_COMMANDs (see page 72).
The audio selected by the Transmitters is embedded on the HDMI signal (if not already embedded) and sent to the switcher (or to
DX-RX in a standalone pair) via the DXLink cable.
The DX-RX will take the embedded audio it receives from a Transmitter** and output the following types of audio:
HDMI Out connector – Embedded digital audio signal
Stereo Audio Out connector – Analog stereo audio signal
** These exceptions apply: In order for audio to be sent out of the analog stereo audio connector on the DX-RX, the audio
must
have originated or be embedded in the HDMI signal on the Enova DGX Digital Media Switcher, Enova DVX Solution, or Transmitter as
a 2 channel signal (either analog stereo or 2 channel L-PCM). Multi-channel (>2 channel) L-PCM formats will pass incomplete audio
(only 2 of the multiple channels will be sent). All other audio formats will be muted at the connector.
