ARCHITECTS & ENGINEERS SPECIFICATION—Q-Sys

The network audio system shall operate on gigabit Layer 3 Ethernet and shall follow accepted IT networking protocols, including QoS, PTP, and UDP/IP. It shall have the capability to stream up to 512 × 512 high-quality 32-bit floating point audio channels across the network, with less than 2.5 ms latency from analog input to analog output, as well as convey control data and listen-bus monitoring signals. 

The system’s main components shall comprise Intel-based centralized processor and control core units, while peripherals may comprise input/output frames configurable for interfacing common analog and digital signals, including microphone and line-level audio, Cobranet, AES3, and Dante, as well as analog outputs to power amplifiers connected through HD-15 ports. Other allowable peripherals shall be network wall-mount touchscreen controllers, network capacitive touch paging stations, and network power amplifiers with the ability to stream 32-bit floating point audio to and from the centralized core processor. Component capabilities or performance shall not be limited by location on the network.

The system shall be capable of complete redundancy, including redundant core processors, redundant LAN structures and also, through the use of switchover accessories, redundant amplifier and I/O frame configuration.
The system shall be controllable using a customizable user control interface via one or more PC and/or iOS devices connected simultaneously to the network. The software shall allow the operating configuration to be designed on a PC that may or may not be connected to the network, and it shall allow configurations to be saved as files that can be stored, backed up, transferred via e-mail or other media, etc.

The system shall be QSC Q-Sys.
