I/O Card Redundancy

AES3 Outputs do not wire together - you must physically switch the output cabling on failover.

For hardware information, see CAES4 – AES-3 Digital Input/Output Card.

Wire the outputs in parallel with the corresponding card in the I/O Frame or Core.

For hardware information, see COL4 – Analog Line Output Card.

CTEL4 card redundancy is not supported. (POTS technology does not support redundant connections.)

For hardware information, see CTEL4 – Analog Telephony Card.

CAN32 card redundancy is not supported.

For hardware information, see CAN32 – AVB Audio Video Bridge Card.

A CobraNet card installed in a Q-SYS Core which is in standby is not automatically suppressed from transmitting and receiving. This might affect your ability to use a redundant pair of Cores populated with CobraNet cards.

For hardware information, see CCN32 – CobraNet Digital Input/Output Card.

See Dante Audio for Dante redundancy requirements.

You must use the DataPort Amplifier Backup panel and have redundant amplifiers. The DataPort card outputs cannot be wired in parallel.

For hardware information, see CODP4 – DataPort Output Card.

Wire the inputs in parallel with the corresponding card in the redundant I/O Frame or Core, for both active circuitry devices requiring phantom power and devices not requiring phantom power such as dynamic microphones.

Note: When phantom power is used, the active circuitry device gets the average of both Mic/Line In card's phantom power, which is +48 VDC. When a failover occurs, the device again gets the average of both Mic/Line In card's phantom power (+48 VDC and 0 VDC) + 24 VDC which should be enough to operate the device.
