I/O Card Redundancy

Requirements for I/O card compatibility with Q-SYS Core or I/O Frame redundancy are listed below.

Note: Redundancy for individual I/O cards within a single I/O Frame is not supported.

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.

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

For hardware information, see COL4 – Analog Line 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.

For hardware information, see:

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.

CAN32 card redundancy is not supported.

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

See Other Networked Audio for Dante redundancy requirements.
