7.1 Surround Sound Audio
DM-NVX-36x(C) devices support the lossless transport of 7.1 surround sound audio
signals (including Dolby® TrueHD, Dolby Atmos®, DTS HD®, and DTS:X® audio signals)
and uncompressed linear PCM. In receiver mode, the DM-NVX-36x(C) can receive both
multichannel and 2-channel downmix signals from a DM-NVX-363(C) or DM-NVX-351(C)
transmitter, allowing either signal to be selected at the HDMI output while the 2-channel
signal is automatically routed to the analog output.
NOTE:
The DSP of the DM-NVX-363(C) is compatible with Dolby Atmos audio using
True HD or Dolby Digital Plus audio formats.
In receiver mode, the DM-NVX-363(C) can receive the incoming multichannel surround
sound signal from the network or from an HDMI input and then downmix that signal to
stereo. The stereo downmix signal is automatically routed to the onboard analog output,
while the HDMI output can be configured to output either stereo or multichannel audio.
In transmitter mode, the DM-NVX-363(C) can distribute both stereo and multichannel
signals simultaneously over the network, allowing either signal to be selected at any
receiver on the network.
To configure 7.1 surround sound audio, set the desired EDID (refer to "EDID" on
page 42).
Analog Audio Input or Output
Analog audio can be configured as either an input or an output:
•
As an input on a DM-NVX-36x(C) device that functions as a transmitter, analog
audio can be configured as the audio source and be inserted into a network video
stream and the HDMI output. As an output on a DM-NVX-36x(C) transmitter, analog
audio can be configured to extract audio from the routed HDMI input.
•
As an input on a DM-NVX-36x(C) device that functions as a receiver, analog audio
can be configured as the audio source and be inserted into the HDMI output. As an
output on a DM-NVX-36x(C) receiver, analog audio can be configured to extract
audio from the routed audio/video source—either the network stream or one of the
HDMI inputs.
NOTE:
Analog audio output from a DM-NVX-360(C) is functional only when the device is
receiving a 2-channel stereo input signal. The DM-NVX-363(C) can derive a 2-channel
downmix signal from a multichannel surround sound source.
To configure analog audio, use the web interface or SIMPL Windows as discussed in the
following sections.
