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

The Q-SYS QIO-PSU is a purpose-built external power supply accessory designed specifically for use with Q-SYS QIO Series I/O expanders. For integrators deploying multiple QIO units across corporate AV systems, higher education environments, hospitality installations, or entertainment venues, the QIO-PSU provides the dedicated power headroom needed to scale modular I/O infrastructure reliably without drawing on host-device resources.

The QIO Series architecture allows networked audio and control I/O to be distributed where it is needed throughout a facility. The QIO-PSU enables that scalability by supporting up to four QIO units from a single external supply, reducing the complexity of power planning in rack or surface-mount installations. This makes it a practical addition for any project where multiple QIO expanders are deployed in close proximity and centralized power management is preferred over individual power sourcing at each unit.

For systems integrators and AV engineers working within the Q-SYS ecosystem, the QIO-PSU is the manufacturer-specified solution to power budget constraints when stacking expanders. It eliminates improvised power workarounds and keeps QIO deployments within supported operating parameters, preserving system reliability and simplifying future serviceability.
