AVB Card (CAN32)

The CAN32 AVB™ bridge card provides third-party AVB enabled digital audio products the ability to connect and interface with Q-SYS™ while maintaining low latency.

Type 2 Hardware

Type 2 hardware provides new cables and connectors between the I/O cards and main boards in Cores and I/O Frames. Due to this change, the Type 2 hardware is not physically compatible with the older hardware. You can still integrate the new I/O Frames and Cores in the same system with older hardware, but the I/O cards are not interchangeable. Type 2 hardware can be identified by a yellow label on the back of the Core and I/O Frame, and the bottom of the I/O cards.

Configure the AVB I/O Card

The Q-SYS CAN32 AVB I/O Card is user configurable via Q-SYS Designer version 4.2.x or greater, including ability to make Direct connections via Full Stream ID (no AVDECC in Q-SYS)

Configurable via third-party software applications supporting the AVDECC control protocol as defined in IEEE 1722.1

IEEE 1722.1 AVDECC Descriptors

The Q-SYS CAN32 AVB I/O Card supports the following IEEE 1722.1 AVDECC descriptors:
