The Q-SYS QIO-FLEX4A expands your Q-SYS system’s capabilities to enable streamlined interoperability with non-networked audio and control devices. By separating local I/O from processing hardware, the QIO Series offer modular and easily scalable network I/O to support your desired topology.

Features

Native network audio and control connectivity solution for Q-SYS
Four (4) software-configurable Flex audio I/O channels
4 x 8 GPIO and one (1) RS232 serial port for integration with third-party control peripherals
Two (2) amplifier outputs for compact loudspeakers
Power-over-Ethernet (PoE) capable
Daisy-chain up to four QIO expanders on a single network run (with local daisy-chained DC power)
Simple drag-and-drop integration and comprehensive management via Q-SYS Designer Software and Q-SYS Reflect
Surface- or rack-mountable (1RU, half-rack width)
Includes surface mounting hardware
