Q-SYS QIO-PSU External Power Supply For QIO Series Expanders

The Q-SYS QIO-PSU is the manufacturer-specified external power supply for integrators building out distributed I/O infrastructure with QIO Series expanders. In corporate AV systems, higher education environments, hospitality installations, and entertainment venues, multi-unit QIO deployments quickly run up against host-device power limits. The QIO-PSU resolves that constraint by providing dedicated power headroom for up to four QIO units from a single external source, eliminating improvised workarounds and keeping every expander within Q-SYS supported operating parameters.

For rack or surface-mount installations where multiple QIO expanders are concentrated in one location, centralized power management through the QIO-PSU simplifies both the initial design and long-term serviceability. Rather than sourcing power individually at each unit, integrators can consolidate supply, reduce cable complexity, and plan power budgets with confidence. This approach preserves system reliability across the full QIO architecture and reduces the number of variables during commissioning and troubleshooting.

AV engineers working inside the Q-SYS ecosystem will find the QIO-PSU essential for any project that calls for scalable, modular I/O distribution. Because it is purpose-built for QIO Series compatibility, it removes the compatibility risk associated with third-party power solutions and ensures the installation remains fully supported by the manufacturer throughout its service life.
