Q-SYS QIO-ML2x2 Series Network Audio Expanders

Product Type:

Brand: AV Store


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.​​​

Features & Benefits:-

  • Native network audio I/O solution for Q-SYS
  • QIO-ML4i: Four (4) mic/line inputs
  • QIO-L4o: Four (4) line outputs
  • QIO-ML2x2: 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
  • Surface- or rack-mountable (1RU, quarter width)
  • Includes surface mounting hardware
  • Professional mic/line connectivity where you need it: QIO Series network audio I/O expanders allows you to provide your Q-SYS system with greater flexibility to deploy mic/line audio connectivity where it’s 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 is intended to present 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. Additionally, QIO Series lets you customize your I/O configuration, and compliments the strengths of newer Q-SYS Core models that were designed with fewer onboard I/O options (Core Nano, Core 8 Flex, or NV-32-H (Core Capable)
  • Simplicity & scalability: Daisy-chain up to four of the QIO Series devices on a single network run (with local daisy-chained DC power) to consume fewer network ports, avoid rack clutter, and allow for quicker future expansion without pulling additional network cables. Alternatively, QIO Series are also PoE-capable, providing simple single cable connectivity (when devices aren’t daisy-chained).
  • Designed for Q-SYS: The QIO Series deliver native network I/O customization to Q-SYS, a cloud-manageable audio, video and control platform, built to deliver scalable, flexible AV solutions into the future.
