DM NAX Audio over IP (AES67)
DM NAX™ audio over IP supports the AES67 standard. AES67 support allows the
selected audio source to be transmitted as a 2-channel AES67 source while another 2-
channel AES67 audio stream is received from a Crestron DSP or other third-party device
and combined with the video signal. When the DM-NVX-36x(C) device functions as a
transmitter, the received AES67 audio stream can be output via the local HDMI output,
primary AV stream, secondary audio stream, and analog audio output. When the
DM-NVX-36x(C) device functions as a receiver, the received AES67 audio stream can be
combined with the video and then output via the HDMI output and analog audio output.
NOTE:
An AES67 stream that is received by an endpoint cannot be transmitted from
that endpoint.
To configure DM NAX (AES67) audio, use the web interface or SIMPL Windows as
discussed in the following sections.
Using the Web Interface
Configure DM NAX (AES67) audio by clicking the Settings tab and then configuring DM
NAX (AES67) audio and routing:
•
The DM NAX (AES67) Audio section varies depending on whether the DM NVX
endpoint is in Transmitter or Receiver mode. Refer to the “Configuring DM NAX
(AES67) Audio for a DM NVX Transmitter” and “Configuring DM NAX (AES67)
Audio for a DM NVX Receiver” sections as appropriate.
•
The Routing section enables the appropriate settings to be configured for DM
NAX (AES67) audio. Refer to the “Configuring DM NAX (AES67) Audio Routing”
section.
Configuring DM NAX (AES67) Audio for a DM NVX Transmitter
In the DM NAX (AES67) Audio section under the Settings tab:
•
In the DM NAX (AES67) Transmit section, select the desired setting in the Mode
drop-down list: Automatic, Disabled, or Manual. The default setting is Automatic,
which adds 1 to the outgoing video stream multicast address. For example, if the
video multicast address is 239.8.0.0, the DM NAX (AES67) multicast address is
automatically set to 239.8.0.1.
If Mode is set to Manual, enter the desired multicast address and port number.
•
In the DM NAX (AES67) Transmit Advanced section, set the Auto Initiation toggle
switch in the On (right) position or Off (left) position. By default, Auto Initiation
is set to On. If Auto Initiation is set to Off, start or stop the stream as desired.
The following AES67 audio stream information is displayed: status, encoding
format, encoding sample rate, bit rate, and number of channels.
•
In the DM NAX (AES67) Receive section, enter the multicast address and port
number.
