ProductsQ-SYS Integrated System PlatformCore Series › Core 250i--500i

Q-Sys is a suite of powerful tools that make any network audio system's requirements easy to achieve. It provides rock-solid performance backed by unrivaled service and support. The Core is at the heart of the Q-Sys Network Audio System performing all the audio routing, processing and control functions. Based on a centralized processing architecture, all processing take place in one unit and any input can be routed to any output without convoluted signal paths offering system designers complete flexibility and simplifying system redundancy.

Q-Sys Cores are available in two configurations, Enterprise Core models (Core 1100 and 3100) and Integrated Core models (Core 250i and Core 500i). Enterprise Cores are ideal for larger systems where high channel combined and increased channel flexibility are paramount while Integrated Cores bring the power and elegance of the larger Q-Sys Cores to applications requiring smaller channel count.  Enterprise Cores require the use of external I/O devices such as I/O Frames or CXD-Q amplifiers and can support channel counts of 64 Flex Channels (Core 1100), 128x128 (Core 3100). Integrated Cores have the capability of directly accommodating eight Q-Sys input and/or output cards for a total onboard channel capacity of 32 channels (more if AES or CobraNet™ cards are used). Integrated Core channel count may be further expanded by the addition of Q-Sys I/O Frames, CXD-Q amplifiers and other peripheral devices to a maximum of 64 Flex Channels on the Core 250i and 128 Flex Channels on the Core 500i.



A second Core can be connected to the network acting as a backup to the primary core. Should the primary core fail, the secondary core takes over all processing for the entire system making a Q-Sys system more robust than a typical distributed system. Any element of a Q-Sys system - Cores, networks, I/O Frames and even amplifiers may be deployed in a redundant configuration; the system designer has the choice of making one or all system elements redundant.

Applications - Q-Sys Cores are an ideal for boardrooms, conferencing, convention centers, entertainment venues, hospitality, houses of worship, legislative installations, performing arts, sports bars, stadiums and arenas, theme parks and transportation facilities.

Platform - Using a customized Linux OS and running on Intel® microprocessors, Q-Sys Cores are amazingly powerful. Because Q-Sys doesn't depend on proprietary DSP hardware, they directly benefit from advancements driven by the entire global Computing / IT industry, and software improvements don't require new hardware.

Network - Q-Sys utilizes IT-friendly Layer-3 Gigabit Ethernet implementation. The audio transport is low-latency (fixed at 2.5 ms from any input to any output) and based on accepted IP standards. Q-Sys will operate using a variety of available, off-the-shelf Gigabit switches (see the QSC web-site for a list of qualified switches). Because it is standards based it can easily run on a shared network without segregating audio traffic via tedious VLAN configuration. 

Design GUI - Q-Sys cores are configured using an intuitive object-based drag and drop user interface that provides for the creation of nearly any imaginable signal flow. Control logic objects are provided and custom scripting may also be used to accomplish a wide range of interface or control tasks. The design GUI is capable of quickly and easily generating graphical control screens that may be run on network-connected computers, tablet devices or QSC touch-screen controllers.

Peripherals - Q-Sys capabilities are further enhanced by a growing suite of peripheral devices including page stations, touch-screen controllers and specialized I/O cards
