This QSC Q-SYS QIO-ML4i Q-SYS Network 4-Mic/Line Inputs Expander extends your Q-SYS system’s capabilities and enables streamlined interoperability with non-networked audio devices. By separating local I/O from processing hardware, the QIO Series offers 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.
Professional mic/line connectivity where you need it: QIO Series network audio I/O expanders provide your Q-SYS system with greater flexibility to deploy mic/line audio connectivity where it is most convenient.
The network audio I/O expanders feature professional mic/line-level inputs with +48 VDC phantom power and/or line outputs to ensure high performance and compatibility, along with microphone detection on inputs to enable monitoring, usage statistics, and failure notifications.
Additionally, each of the three models features a compact form factor that can be rack- or surface-mounted.
Expanded I/O customization: QIO Series provides a simpler way to add network I/O connectivity to Q-SYS systems, decoupling the physical location of the I/O from processing hardware to support distributed or centralized processing architectures.
QIO Series also lets you customize your I/O configuration and complements newer Q-SYS Core models designed with fewer onboard I/O options, including Core Nano, Core 8 Flex, and NV-32-H (Core Capable).
Simplicity and scalability: Daisy-chain up to four QIO Series devices on a single network run with local daisy-chained DC power to consume fewer network ports, reduce rack clutter, and allow quicker future expansion without pulling additional network cables.
Alternatively, QIO Series devices are PoE-capable, providing simple single-cable connectivity when devices are not daisy-chained.
Designed for Q-SYS: QIO Series delivers native network I/O customization to Q-SYS, a cloud-manageable audio, video, and control platform built to deliver scalable, flexible AV solutions.
