Stream Setup
The digital AES67 4 wires are configured in the stream setup.
Different parameters are available depending on whether an input or output is configured.

General Settings
Multicast IP
Field to enter the Multicast address of the RTP sender (224.0.0.0 ...
239.255.255.254)
Inputs
: The
button allows loading the settings from a SDP file.
Outputs
: The
button allows saving the settings to a SDP file.
Multicast Port
Field to enter the Multicast port of the RTP sender (0 ... 5004 ... 65535)
Sender IP
1
Field to enter the IP address of the sender in case of IGMPv3.
Select another channel of
this stream for Audio B
2
If this function is activated, a second audio channel can be selected in
this window, which is routed to/from the audio patch 'Audio B'.
Bit Depth
Selection of the Bit resolution. (L16, L24)
Channels
Amount of used audio channels in the AES67 stream. (1 ... 64)
Audio Input from
Stream Channel
Selection of the audio channel to be received/transmitted in this port.

Packet Settings
Packet Time
Packet time is the real-time duration of media data in a packet. Samples
per packet are calculated from packet time and sampling rate. Short
packet time allows for lower latency, but requires more bandwidth due
to overhead. Implemented for interoperability reasons.
Depending of selected amount of audio channels and the bit depth,
shorter packet times are available. (0.125, 0.250, 0.333, 1.000 or 1.333
ms)
Play Mode
3
Selection between Synton and Synchron.
In Synchron mode audio packets will be discarded if the PTP timestamp
is missing or invalid. Hence only audio signals are output if they are
transmitted in a PTP synchronized network.
In Synton mode audio packets without or with invalid PTP timestamps
are processed and output, hence this mode can be used in networks
without PTP synchronization.
Receive Buffer
3
Selection of the size of the AES67 receive buffer to adapt the expected
delay of connected panels. The default buffer is 3 × Packet Time.
The longer the selected packet time, the shorter is the available receive
buffer. (0.375 ... 99 ms)
Media Clock Offset
Selection of the Time Stamp Offset. (0...32)
SSRC
Selection of the synchronization source. (0...32)
Payload Type
Selection of the Payload type. (96...127)
