AVB In
The AVB Input and Output are on the same physical card but are represented in the Q-SYS design by an AVB Input Component and an AVB Output Component.
The AVB Intput component provides connections for inputs up to 32 channels in 4 streams for devices supporting the AVB protocol. Other combinations of input/output are described in the Properties section below. Connection is made with CAT-5 / RJ-45 connector.
For hardware information, see CAN32 – AVB Audio Video Bridge Card.

Listener Stream Connections
There are two ways you can connect an AVB Listener to an AVB Talker:
- AVDECC (1722.1) (see https://avb.statusbar.com/article/1722.1-features/): This is the typical method and it involves a 3rd-party AVB management software for example: Riedel AVB Manager or Pivitec's AVDECC Controller. There are others available.
- Directly via "Full Stream ID": Each stream on the network has a unique 64-bit stream ID (Full Stream ID). If you know the Full Stream ID you can just tell your Listener to listen to that stream and bypass AVDECC and any related third-party software.

Function |
Default / Range |
---|---|---|
Clear (Momentary button) |
Removes all Listener/Talker mapping (AVDECC or Full Stream ID), disconnects the Listener from the Talker and audio stops. |
N / A |
AVDECC Entity and Unique ID |
Read Only. IEEE-defined 64-bit Extended Unique Identifier of an AVDECC Entity. These codes are automatically derived from the Talker Stream connected to the Listener. |
N / A |
Full Stream ID |
Read/Write. Enter the Unique 64-bit stream ID of the Talker Stream. When this information is entered, it removes the AVDECC information for that stream. |

Talker Channels / Stream |
You can have from 2 to 32 channels per stream. If you select 32 (in or out) channels, and 2 channels per stream, the maximum number of channels is 24. If you select 16 x 16 channels and 1 listener channel per stream, the inputs are limited to 14. |
