AVB Out
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 Output component provides an output 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.
