QSC QIO-FLEX4A – Q-SYS Multi-Purpose Flex I/O Expander
Product Overview
The QSC QIO-FLEX4A is the most versatile I/O expander in the QIO Series, offering four independently software-configurable channels that can each be set as a mic/line input (with 48V phantom power) or a balanced line output — all via Q-SYS Designer Software without hardware jumpers or DIP switches. This software-defined flexibility makes the QIO-FLEX4A the preferred single-unit solution for small rooms requiring a mix of inputs and outputs at the room edge, or for installations where I/O requirements may change after deployment. Connecting via standard Ethernet, it integrates natively with any Q-SYS Core processor and appears as a fully managed network device in Q-SYS Designer.
Key Features
- 4 software-configurable Flex channels — Each independently set as mic/line input (48V phantom) or balanced line output; configuration changed in Q-SYS Designer without hardware modifications.
- Maximum room-edge flexibility — Single device handles any combination of inputs and outputs for huddle rooms, small conference rooms, and supplemental I/O points.
- Native Q-SYS integration — Full routing, gain, phantom power, and metering managed from Q-SYS Designer.
- No hardware reconfiguration — Flex channel mode changes are software-only; no re-wiring or jumper changes required post-installation.
- Compatible with all Q-SYS Core processors
- QIO-RMK rack tray compatible
Typical Applications
- Huddle room (combined mic input + speaker output from one unit)
- Small conference room
- Supplemental I/O at display or equipment location
- Flexible multi-purpose room (I/O requirements vary by event)
