The Q-SYS QIO-TEL2 expands your Q-SYS system’s capabilities to enable streamlined interoperability with analog telephony systems. 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 & Benefits

  • Native analog telephony connectivity solution for Q-SYS
  • Two (2) POTS phone lines on standard RJ-11 connectors
  • 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 Enterprise Manager
  • Surface- or rack-mountable (1RU, quarter width)
  • Includes surface mounting hardware
  • Network analog telephony connectivity where you need it
    TThe QIO-TEL2 allows you to provide your Q-SYS system with greater flexibility to deploy analog telephony connectivity where it’s most convenient. The QIO-TEL2 provides two (2) POTS phone lines on standard RJ-11 connectors. It integrates analog telephony into Q-SYS, including PSTN subscriber lines, PBX phone and paging systems, and other retrofit applications where the use of VoIP is not possible due to security or cost. Additionally, each of the QIO Series I/O expanders 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.
