QIO Series High-density Audio Expanders
Q-SYS Network Mic/Line I/O Expanders
The Q-SYS QIO Series network audio expanders enable interoperability with non-networked audio I/O to expand the power of Q-SYS across more devices. The QIO-ML24i, QIO-L24o and QIO-24f address the I/O needs of larger systems with a single peripheral rather than multiple smaller devices, making them ideal for applications such as event productions, large hospitality installations, paging systems, judicial spaces and more.
Features & Benefits
- Native, high-density audio I/O for Q-SYS
- QIO-ML24i: Twenty-four (24) mic/line level inputs
- QIO-L24o: Twenty-four (24) line level outputs
- QIO-24f: Eight (8) mic/line level inputs, eight (8) software-definable Flex channels and eight (8) line level outputs
- Supports both network and peripheral redundancy
- 1RU form factor
- 8 x 8 GPIO to integrate third-party device control connectivity
- Configurable +48 VDC phantom power on inputs
- Microphone detection on inputs enables monitoring, usage statistics, and failure notifications
- Integrated relay mute on outputs enables redundant audio output for peripheral redundancy and prevents power-up transients
- Two (2) gigabit Ethernet ports for redundant networked audio
- Surface- or rack-mountable
- QIO-CK redundancy cable kit (sold separately)
- Add the right I/O where you need it: With QIO Series network audio expanders, you can deploy mic/line audio connectivity into your system to integrate non-networked devices into the Q-SYS Platform. High-density audio I/O expanders deliver 24 channels of audio, as well as GPIO and both network and peripheral redundancy in a 1RU form factor to efficiently integrate a multitude of audio endpoints and simplify the design of larger Q-SYS systems.
- Customizable to your environment: The QIO Series are modular devices that can be combined to fit your unique I/O requirements and processing architectures. By separating I/O from processing hardware, the QIO Series enables you to interface with non-networked audio and control devices precisely where they’re needed. Additionally, software-definable Flex I/O options support dynamic, multi-use systems, letting you adapt as needs change.
- Mission-critical reliability: High-density models deliver redundancy features that ensure seamless audio delivery, even during peripheral or network failure. Q-SYS can automatically direct audio to a backup within seconds if a critical fault is detected to minimize failover time and prevent audio interruptions.
- Integrated audio, video and control: QIO Series network I/O expanders are driven by the Q-SYS Full Stack AV Platform, which unifies data, devices and a cloud-first open architecture to deliver a fully integrated audio, video and control solution that offers simpler integration and software-based scalability.
