The QSC QIO-L24o Q-SYS Network 24-Output Line-Level I/O Expander expands the Q-SYS Platform by integrating non-networked audio devices into networked AV systems. With 24 line-level outputs, it is designed for large-scale installations in event production, hospitality, paging, judicial facilities, and other professional environments.
The QIO-L24o is part of the Q-SYS QIO Series, which provides high-density network audio I/O in a compact form factor. It allows system designers to place audio connectivity where it is needed while keeping processing hardware separate.
Expand your audio output capacity: The QIO-L24o provides 24 line-level outputs for connecting non-networked audio equipment to a Q-SYS system, helping simplify installations that require numerous audio output channels.
Reliable network integration: Two Gigabit Ethernet ports support redundant network connectivity, while supported peripheral redundancy configurations help maintain audio availability when a critical fault occurs.
Flexible installation: The 1RU, full-rack-width design supports rack or surface mounting. The QIO Series can be combined with other compatible I/O expanders to accommodate different system architectures and connectivity requirements.
Integrated audio, video, and control: Driven by the Q-SYS Full Stack AV Platform, the QIO-L24o helps integrate networked audio and control into a unified, software-based AV system.
