Overview
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. The QIO-ML2x2 features two (2) mic/line inputs and two (2) line outputs.
