Q-SYS Designer Software:  Support Policy

QSC strives to bring new software solutions and feature updates to better service our customers. To maximize business performance, you are encouraged to transition systems to the latest Q-SYS Designer Software release.

To ease the transition period from the most recent prior to the current version, QSC will provide technical support, on a best-effort basis, on the most recent prior release of Q-SYS Designer Software (annotated as “End of Life – Supported”) for a period up to twelve (12) months.  After twelve months, the prior software version will no longer be supported by QSC.

Version 7 (End of life – Supported through April 2020)

Featured Updates

  • Shared Layers in UCI Editor – Share layers across multiple pages within a UCI design. This removes the need to create duplicate layers when designing pop-up notifications or page navigation controls into a user control interface.
  • Text Controller Scripting Component – Replaces the Scriptable Controls component, and now allows you to re-order defined controls as well as drag multiple controls from the Elements Editor into your schematic.
  • CTEL4 I/O Card (POTS) Support – The CTEL4 Analog Telephony I/O Card is now configurable within Q-SYS Designer.
  • Dante™ Domain Manager Support – The CDN64 Dante™ Audio Bridge I/O Card is now compatible for use with Dante™ Domain Manager.


This version of Q-SYS Designer Software is no longer available for download.  

We highly recommend that you update your system to the latest Q-SYS software version to take advantage of newer features and improvements.

  • [NEW] – Introduced the Q-SYS Asset Manager, available via the Tools menu, to allow for easy installation of new plugins and updating of plugins directly from within Q-SYS Designer.
  • [NEW] – Introduced the Network Services manager on the Q-SYS Core, accessible via Configurator or web browser, allowing system administrators to disable unused network services on a per-network adapter level, which can increase the security of the Q-SYS system and help to satisfy customer-specific security requirements.
  • [NEW] – Added new External USB Audio Device inventory components, enabled via properties for the Core 110, TSC-7t touchscreen, and I/O USB Bridge, allowing you to connect a standard USB headset, speakerphone, or similar to a compatible Q-SYS device and process the incoming and outgoing audio streams in the Q-SYS audio DSP.
  • [NEW] – Added the Date/Time control component, allowing you to insert a date/time text box into your design. This is especially useful for adding the local date and time to a user control interface (UCI).
  • [NEW] – Added the Selector control component, allowing you to easily switch between a number of configured values to send to a downstream component.
  • [NEW] – Added the Value Stepper control component, allowing you to easily increase or decrease values of a downstream component in either gain or percentage terms.
  • [NEW] – Added the UCI Layer Controller control component, allowing you to show or hide individual layers in a specified UCI and page.
  • [CORE] – To make Q-SYS Cores less vulnerable to network attacks, the FTP Server on the Core has been removed. If you use FTP (implemented in custom software or a standard FTP program, such as FileZilla) to upload or download media files to or from a Q-SYS Core, QSC recommends that you wait to upgrade to version 7.1 until you can update your client software to use either HTTP or HTTPS. As a more secure alternative to FTP, use HTTPS.
