QIO Series

Q-SYS Network I/O Expanders

The Q-SYS QIO Series network I/O expanders extend your Q-SYS system’s capabilities to enable streamlined interoperability with non-networked audio and control devices. By separating local I/O from processing hardware, the QIO Series offer modular and easily scalable network I/O to support your desired topology. Each model supports a different, specific connectivity type, from mic/line audio I/O to control (IR, Serial, or GPIO).

The Right I/O Where You Need It

Provide your Q-SYS system with greater flexibility to deploy mic/line audio, digital audio, VoIP, and control connectivity where it’s most convenient. Each QIO Series model offers a single connectivity type in a compact form factor that can be rack- or surface-mounted.

Expanded I/O Customization

Add network I/O connectivity to Q-SYS systems and decouple the physical location of the I/O from processing hardware to support distributed or centralized processing architectures.

Expand Native Q-SYS Audio and VoIP Connectivity

Select from a line of QIO audio models that  support professional mic/line level inputs with +48 VDC phantom power, AES3 digital audio I/O, and analog telephony into Q-SYS.

Expand Control Connectivity For Non-native Q-SYS Devices

Add IR, Serial, or GPIO connectivity to integrate control for a wide range of devices into your Q-SYS system.

Simplicity & Scalability

Daisy-chain up to four QIO Series devices on a single network run (with local daisy-chained DC power) to consume fewer network ports and allow for quicker future expansion without pulling additional network cables. Alternatively, QIO Series are PoE-capable, providing simple single cable connectivity (when devices arent daisy-chained).
