AES3 In / Out

The AES3 Input / Output in Q-SYS Designer has two associated components that you can add to your design; an Input Component, and an Output Component. The AES3 Card gives you a total of four inputs and four outputs (two input ports and two output ports) of AES3 digital audio.

You can also use the AES3 inputs to sync Q-SYS to an external clock source. Refer to the Core Status topic for details. The AES3-1 and AES3-2 options display in the Core's Properties when you have an AES3 In / Out card selected for the Core I/O slot. Use these options to sync to an external AES3 signal. The AES3 selections require either regular AES3 or AES3 black. The clock should be connected to the AES3 card either connector Channel 1/2 In, or Channel 3/4 In.

Note: Typically, Internal is used as the clock source. Only if there is a need to synchronize the Q-SYS system to an external clock would you use GPIO or AES3. You would use GPIO if the external clock signal is a word clock. You would use AES3 if the external clock signal is an AES3 signal. Often an AES3 signal without audio is used to reduce the clock jitter. This signal is called AES3 black.

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.
