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.

Peak Input Level (dBFS) |
Meters for each channel indicating the peak AVB input level. The measurement is taken before the Digital Gain. |
Default = N / A Range = -120 to 20 |

There are two ways you can connect an AVB Listener to an AVB Talker:
Control |
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. |

Input/Output Count |
2x2 - 2 channels in, 2 channels out 4x4 - 4 channels in, 4 channels out 8x8 - 8 channels in, 8 channels out 16x16 - 16 channels in, 16 channels out 32x0 - 32 channels in, 0 channels out (no Output Component) 0x32 - 0 channels in, 32 channels out (no Input Component) |
2x2 4x4 8x8 16x16 32x0 0x32 |
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. |
1, 2, 4, 8, 16 |
Listener 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 talker channel per stream, the outputs are limited to 14. |
1, 2, 4, 8, 16 |
The available Control Pins depend on settings in Properties.
Each channel on the AVB Input card has the following Control Pins.
