Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
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
Stereo Audio In jack – Analog stereo audio signal
The hierarchy for audio type precedence* is listed in the following table for the Transmitters:
The audio selected by the Transmitters is embedded on the HDMI signal (if not already embedded) and
sent to the switcher (or to an HDMI RX in a standalone pair) via the DXLink cable.
* Audio precedence as specified in the table above can be overridden by SEND_COMMANDs (see
page 80).
Regardless of the type of audio coming into the Transmitters, the HDMI RX will always 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
In order for audio to be sent out of the analog stereo audio connector on the HDMI RX, it must have
originated or be embedded in the HDMI signal on the Enova DGX 16/32, Enova DVX Solution, or
Transmitter as a 2 channel signal (either analog stereo or 2 channel PCM).
Note: When digital audio and/or analog stereo audio cables are plugged in, the Audio LEDs on the
front of the modules turn green to show that audio is present and is being incorporated into the
HDMI line and is also available on the HDMI RX at the Stereo Audio Out connector.
