The COL4 card provides four channels of balanced, line-level analog output for interfacing between Q-SYS and outboard equipment such as non-DataPort amplifiers, recording devices and teleconference systems.
For configuration information, see Line Out.
About Type 2 Hardware
The COL4 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.
