Q-SYS QIO-ML2x2 Network Audio Mic/Line I/O Expander

The Q-SYS QIO Series network audio I/O expanders extend your Q-SYS system's capabilities and enable streamlined interoperability with non-networked audio 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. There are three models that offer mic/line connectivity to integrate consumer or professional audio devices into your Q-SYS system.

• Native network audio I/O solution for Q-SYS
• Two (2) mic/line inputs and two (2) line outputs
• Professional, high performance mic/line level inputs (with +48 VDC phantom power) and/or line outputs
• Microphone detection on inputs to enable monitoring, usage statistics and failure notifications
• Power over Ethernet (PoE) capable or 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 Enterprise Manager
