The Q-SYS I/O-8 Flex Channel Expander adds several expansion capabilities to the Q-SYS platform.

Note: This topic provides an overview of the I/O-8 Flex. For specifications and installation documentation, see the I/O-8 Flex product page on the QSC website.

  • Eight flex channels (software configurable as either a Mic/Line input with phantom power, or a Line Level output)
  • Audio-to-USB Bridging for integration with soft-codec applications for host PC
  • Control connectivity via GPIO and RS232
  • Versatile mounting accessories included
  • PoE+ or external power supply (not included)

The following components are available for the I/O-8 Flex, depending on its Properties.
