Installation and Setup

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 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:

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 is applicable when the AUDIN_FORMAT_AUTO

command is set to ENABLE; this precedence can be overridden by SEND_COMMANDs (see page 90).

The type of audio coming into the Transmitters, the HDMI 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

HDMI RX, it 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 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.
