  • 24 Line Outputs Enable High-Density Analog Distribution From A Single Peripheral
  • Dual Gigabit Ethernet Ports Support Network Redundancy For Mission-Critical Installs
  • 8 x 8 GPIO Provides Direct Integration With Third-Party Control Systems
  • Relay Mute Suppresses Power-Up Transients To Protect Downstream Amplifiers
  • 1RU Full-Rack Width Chassis Minimizes Rack Space In Large-Format Systems
  • Surface Or Rack Mounting Options Adapt To Varied Installation Environments

The Q-SYS QIO-L24o is a network-attached I/O peripheral built for AV integrators who need to scale analog output capacity without multiplying rack footprint. Delivering twenty-four line level outputs from a single 1RU unit, it eliminates the patchwork of smaller devices that accumulates in larger systems and centralizes audio distribution under a clean, manageable infrastructure. It is well-suited for enterprise installations where output count, signal integrity, and rack efficiency all matter equally.

Professional AV environments with demanding routing requirements find direct application here. Hospitality properties distributing background audio across zones, judicial facilities requiring discrete channel feeds, corporate event spaces running paging and program audio simultaneously, and multi-room conference centers all benefit from the density this unit provides. The 8x8 GPIO expander enables straightforward integration with third-party control systems, and the relay mute circuit suppresses power-up transients that could damage downstream amplifiers or embarrass an install during commissioning.

Where comparable expanders require separate redundancy accessories or lack native GPIO, the QIO-L24o includes dual gigabit Ethernet ports for network redundancy and supports peripheral redundancy via the optional QIO-CK cable kit. Surface or rack mounting gives integrators flexibility in mechanical installation. These design decisions reflect a product built for permanent, mission-critical installs rather than temporary deployments, making it a dependable choice when output density and system reliability are non-negotiable.
