The QSC QIO-ML24i Q-SYS Network 24 Mic/Line I/O Expander enables interoperability with non-networked audio equipment, expanding the connectivity and capabilities of Q-SYS systems.
The QIO-ML24i, QIO-L24o, and QIO-24f address the I/O needs of larger systems with a single high-density peripheral rather than multiple smaller devices. Applications include event production, large hospitality installations, paging systems, judicial spaces, and more.
Add the right I/O where you need it: QIO Series network audio expanders integrate non-networked audio devices into the Q-SYS Platform, allowing audio connectivity to be placed where it is needed.
High-density audio connectivity: The QIO-ML24i provides 24 mic/line inputs, GPIO, and network and peripheral redundancy capabilities in a compact 1RU form factor.
Customizable to your environment: QIO Series devices can be combined to accommodate different I/O requirements and processing architectures.
By separating I/O from processing hardware, the QIO Series helps connect non-networked audio and control equipment at convenient locations. This approach supports flexible system designs and easier expansion.
Mission-critical reliability: Redundancy capabilities help maintain audio availability during supported network or peripheral failures. Compatible Q-SYS configurations can route audio to a backup device when a critical fault is detected.
Integrated audio, video, and control: QIO Series network I/O expanders operate within the Q-SYS Full Stack AV Platform, supporting integrated audio, video, and control system designs.
