QSC QIO-24f – Q-SYS 24-Channel Flex I/O Network Audio Expander

What is the QSC QIO-24f?

The QSC QIO-24f is the highest-channel-count Flex I/O expander in the QIO Series, providing 24 software-configurable channels: 8 mic/line inputs, 8 software-definable Flex channels (configurable as mic/line input or line output), and 8 fixed line outputs — all in a 1U rack-mount chassis. It is the direct Q-SYS network peripheral equivalent of the Core 24f's onboard I/O architecture, designed for large-room deployments where substantial analog I/O capacity is required at a distributed location without running cable back to the Core rack. Like all QIO expanders, it integrates natively with any Q-SYS Core and is managed entirely in Q-SYS Designer Software.

Key Features

• 24 total analog channels — 8 mic/line inputs, 8 software-definable Flex (input or output), 8 line outputs; mirrors the Core 24f I/O architecture at the room edge.
• Software-defined Flex channels — 8 channels independently configurable as mic/line input (with phantom power) or line output in Q-SYS Designer.
• Native Q-SYS integration — Full routing, gain, metering, and phantom control from Q-SYS Designer; no separate DSP or I/O controller.
• 1U rack-mount — High-density analog I/O in a standard rack-mount form factor.
• Ideal for large-room distributed I/O — Conference rooms, boardrooms, houses of worship, and auditoriums requiring substantial channel count at the room edge.

Frequently Asked Questions

How does the QIO-24f differ from smaller QIO expanders like the QIO-ML4i or QIO-L4o?
The QIO-24f combines both input and output capacity in one 24-channel chassis, while the QIO-ML4i and QIO-L4o are dedicated 4-channel input-only or output-only units. Choose the QIO-24f when a single room edge needs high-density mixed I/O rather than several smaller expanders.

Are the Flex channels independently configurable?
Yes. Each of the 8 Flex channels can be set individually as a mic/line input (with phantom power) or a line output from Q-SYS Designer, without any hardware changes.

Does it require a specific Q-SYS Core?
No. The QIO-24f is a native Q-SYS peripheral that works with any current Q-SYS Core processor over a standard gigabit network, the same as other QIO expanders.

Can it be combined with other QIO peripherals?
Yes. The QIO-24f operates alongside other QIO expanders in the same Q-SYS design when a project needs additional distributed I/O beyond its 24 channels.

What about warranty and support?
The QIO-24f is covered under QSC's standard warranty terms. Contact Creation Networks support for Q-SYS design and AV integration assistance.
