Q-SYS Remote Control Protocol (QRC)

Q-SYS Remote Control (QRC) is the newer and most advanced means to allow an external control system to control various functions within Q-SYS. As opposed to the External Control Protocol (ECP), which requires the use of Named Controls for any control needing external control, QRC allows multiple levels of control at the component level. And, unlike ECP, you do not need to drag every control you want to control into the Named Controls pane and creatively name each control for external access.

QRC includes these features:

• Named Controls
• Component Control – Control any control within any component by customizing the name of the component to make it unique.
• Mixer Control – Specialized control of mixers using mixer concepts rather than unintelligent control of each individual control
• PA Router Control – A powerful API for integrating third-party control of the PA Router functionality. This was specifically designed to allow message assembly vendors to send audio files, control, and monitor the PA Router.

Refer to the QRC Commands topic for details on controlling Q-SYS using this protocol. Refer to the Q-SYS PA Remote API (PARAPI) topic for information on how to use QRC for interfacing third-party applications with the PA Router for paging applications.
