QSC Q-SYS Core 8 Flex

Q-SYS network + analog I/O processor

The Core 8 Flex audio, video and control (AV&C) processor extends the applications of the Q-SYS Ecosystem into a wider range of smaller-scale installations across corporate, higher education, healthcare and beyond. Built on the same foundational technology as the rest of the Q-SYS processor portfolio, including the best-in-class Q-SYS Core 110f, Core 8 Flex is designed for applications with lower network or analog channel capacity and/or targeted processing requirements.

Network plus on-board I/O

In addition to its 64 x 64 network I/O capacity, the Core 8 Flex offers eight on-board Flex channels and eight GPIO on-ramps to integrate analog audio and control devices into the Q-SYS Ecosystem. Ideal for in-room processing with both analog & networked endpoints.

Rightsized. Uncompromised.

Rather than deploying an AV&C processor with unused analog I/O that occupies a full rack space, Core 8 Flex offers a smaller solution with several mounting options. However, its smaller form factor does not compromise on functionality; instead Core 8 Flex delivers a full featured control engine for third-party device control, full paging and BGM capabilities, automation, monitoring and beyond.

Optimized for the Meeting Space

The Core 8 Flex provides the AV infrastructure to enable full room web conference integration, particularly for larger, more challenging spaces. It features USB integration with all major web conferencing applications, eight channels of acoustic echo cancellation (AEC), two VoIP softphones, Software-based Dante to enable modern microphones, and a full-featured control engine for third-party device integration.

Reduce Complexity and improve scalability with the Q-SYS Ecosystem

The Q-SYS Core 8 Flex joins a growing Ecosystem of AV&C processors built on a flexible software foundation. Like all Q-SYS Core processors, the Core 8 Flex lets integrators take full advantage of the same Q-SYS software suite to design and configure systems, and end users can take full advantage of all native Q-SYS peripherals and the system’s ability to scale your system without having to rip-and-replace your configuration file.
