QIO-24f

The Q-SYS QIO-24f is a network audio endpoint native to the Q-SYS Ecosystem, serving as a set of audio inputs and outputs that enables network-based audio distribution. The form factor of this product facilitates a high density of 24 analog audio connections in a standard 1U rack space, ideal for applications that require a large number of audio connections. The QIO-24f offers eight mic/line input connections, eight FLEX I/O connections that can be used as inputs or outputs, and eight line output connections; along with 8x8 GPIO ports for control. Dual Ethernet connectors provide optional network redundancy, and two of these products can also be installed in a redundant failover pair to guard against unexpected audio interruptions in critical applications.

Note: This topic provides an overview of the QIO-24f. For specifications and installation documentation, see the QIO Series High-density Audio Expanders product page on the Q-SYS website.

  • Native, high-density audio I/O for Q-SYS

  • Eight (8) mic/line level inputs, eight (8) software-definable Flex channels and eight (8) line level outputs

  • Supports both network and peripheral redundancy

  • 1RU form factor

  • 8 x 8 GPIO to integrate third-party device control connectivity
