Created from the ground-up, Q-SYS is a software-based platform built around an open IT-friendly ecosystem. It uniquely leverages the power of Intel processing, the robustness and mission critical reliability of a Linux operating system, and the interoperability of IEEE networking standards. This IT-centric layered approach allows QSC to easily migrate the Q-SYS Platform to other Intel platforms as they introduce new, faster chipsets, and to other off-the-shelf hardware. Furthermore, its usage of IT standard protocols makes the Q-SYS Platform highly extensible for future IT functions and platforms.

Core 510i

The Q-SYS Core 510i processor is an audio, video and control processing system that leverages Intel™ CPUs and motherboards as well as a dedicated, Linux™ realtime operating system developed by QSC to provide class-leading capabilities for AV systems of any scale.

The Q-SYS Core 510i processor offers the most flexible audio I/O of any Core in the Q-SYS catalogue, perfect for applications that require a diversity of analogue, digital and networked audio connectivity. It features eight onboard I/O card slots that can be populated with any combination of Q-SYS Type-II I/O cards allowing diverse connectivity options. The Core 510i processor also offers two modes of operation whereby it can be deployed as a Q-SYS Core Processor with full processing capabilities, or configured as an I/O expander when configured via software as an I/O-510i.

Applications – Q-SYS Core mode

When deployed as a Q-SYS Core, the Core 510i processor provides an abundance of raw processing power for all audio, video and control requirements including integration with the new Q-SYS AV-o-USB Bridging solution. Onboard acoustic echo cancellation (AEC) processing coupled with high channel capacity networked audio provide the ability to manage multiple small to mid-sized conference spaces or a single large space.

Applications – I/O Frame mode

When configured via software as an I/O-510i, the device offers the ability to add up to 128 x 128 audio channels in to the Q-SYS system for processing on a separate Q-SYS Core. It can accommodate any combination of Q-SYS Type-II I/O cards. This is particularly useful when integrating large numbers of networked audio channels from Dante™, CobraNet™or AVB™ devices and subsystems in to the Q-SYS Platform.


The Q-SYS Platform utilizes IEEE networking standards and solutions for audio, control and video distribution over a standard Ethernet / IP network. Q-LAN provides deterministic system latencies with analogue input to analogue output guaranteed at 3.167ms. The Q-SYS Platform uses Q-LAN for audio, video and control connectivity with all Q-SYS peripherals. Additionally, the Q-SYS Core supports VoIP, SIP, LDAP, AES67, TCP/IP and HTTP Web Sockets among many other standard IT networking solutions.

Scalable Redundancy

While QSC is dedicated to building the most reliable products, some applications call for additional assurance. Any element on the Q-SYS Platform – 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.


The capabilities of the Q-SYS Platform are further enhanced by the ever growing suite of Q-SYS peripheral devices, all of which are compatible with all Q-SYS Core processors, including the Q-SYS Core 510i. The catalogue of Q-SYS networked peripheral devices include amplifiers, touch screen controllers, paging stations, I/O channel expanders, PTZ-IP cameras for the conference room and AV-to-USB Bridging devices.
