Overview
The Q-SYS QIO Series network audio expanders enable interoperability with non-networked audio I/O to expand the power of Q-SYS across more devices. The QIO-ML24i, QIO-L24o and QIO-24f address the I/O needs of larger systems with a single peripheral rather than multiple smaller devices, making them ideal for applications such as event productions, large hospitality installations, paging systems, judicial spaces and more.
Features
- Native, high-density audio I/O for Q-SYS
- QIO-ML24i: Twenty-four (24) mic/line level inputs
- QIO-L24o: Twenty-four (24) line level outputs
- QIO-24f: Eight (8) mic/line level inputs, eight (8) software-definable Flex channels and eight (8) line level outputs
- Supports both network and peripheral redundancy
- 1RU form factor
- 8 x 8 GPIO to integrate third-party device control connectivity
- Configurable +48 VDC phantom power on inputs
- Microphone detection on inputs enables monitoring, usage statistics, and failure notifications
- Integrated relay mute on outputs enables redundant audio output for peripheral redundancy and prevents power-up transients
- Two (2) gigabit Ethernet ports for redundant networked audio
- Surface- or rack-mountable
- QIO-CK redundancy cable kit (sold separately)
