Q-SYS™ Core 8 Flex I/O Processor for Cinema Applications
Preliminary Specification Sheet
Overview
Introducing the Q-SYS Core 8 Flex audio, video and control (AV&C) processor, which extends the applications of the Q-SYS Ecosystem throughout the Cinema complex, including 5.1/7.1 and immersive audio rooms, arcade gaming areas, background/foreground music for food service areas, event rooms, and much more. Built on the same foundational technology as the rest of the Q-SYS processor portfolio, including the best-in-class Q-SYS Core 110c, the Core 8 Flex is designed for applications with lower network channel capacity and/or targeted processing requirements.
Core 8 Flex offers onboard analog audio I/O and GPIO plus network AV&C processing, and like all Q-SYS Core processors, the Core 8 Flex delivers features and functionality at the software level, including acoustic echo cancellation (AEC), wide-area paging, video routing, and a full featured control engine without the need for dedicated control processors.
Features
- 64 x 64 networked audio channels (Q-LAN / AES67)
- Eight on-board FLEX channels and GPIO
- 8 x AEC (acoustic echo cancellation) processors
- Up to 32 x 32 Dante audio channels (8 x 8 included)
- USB AV bridging (8 x 8 audio + Q-SYS camera support)
- External USB audio device host
- Supports up to 2 VoIP softphone instances
- Full featured Q-SYS Control engine
- Dual gigabit ethernet ports with assignable application resources offering any combination of VoIP, Q-LAN Control, Q-LAN audio or network redundancy
- Internal power supply
- 1U half-width, includes mounting hardware
Onboard analog I/O plus network I/O
In addition to its 64 x 64 network audio 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.
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, space-efficient solution with the right amount of analog I/O. However, it does not compromise on functionality; instead it delivers a fully-integrated and customized Q-SYS experience. The Core 8 Flex brings all of the power and flexibility of the Q-SYS Ecosystem to even the smallest rooms within a multiplex at price point that's comparable to a conventional cinema processor. With 64 x 64 networked audio channels and eight onboard "flex" channels (configurable as either input or output) for analog connectivity, you can even use Core 8 Flex for small to medium sized immersive audio applications.
Choose either a single Core 8 Flex for each room in a multiplex, or choose to run several 5.1/7.1 rooms from one single Core 8 Flex.
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 that delivers features and functionality without relying on dedicated, single-purpose hardware. Like all Q-SYS Cores, the Core 8 Flex let integrators take full advantage of the same Q-SYS software suite to design and configure systems, and end users can benefit from a more holistic user experience as a result of all native Q-SYS peripherals, and the system's ability to scale your system without having to rip-and-replace your configuration file.
