CAES4 – AES-3 Digital Input/Output Card

The CAES4 provides four input and four output channels of AES-3 digital audio for interfacing between Q-SYS and digital devices such as mixing consoles and recording devices.

For configuration information, see AES3 In / Out.

The CAES4 card is 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.
