QSC and Q-SYS products are used by audio and video professionals for commercial applications, including corporate, higher education, sports venues, themed entertainment, and cinema customers worldwide.

The company holds five offices in the United States, including Austin, Boulder, Fort Wayne, San Luis Obispo, and its headquarters in Costa Mesa, with further international presence in London, Nieuwegein, Sinsheim, Zurich, Wattens, Dubai, Hong Kong, Beijing, Singapore, Bangalore, and Tokyo.

Meanwhile, QSC developed more conventional sales channels in retail music and pro audio stores and also started working with export distributors.

MediaLink, however, did not prove robust enough for professional audio users, so by the mid 1990s QSC abandoned it in favor of Ethernet-based networking, which was becoming more affordable and ubiquitous.

The agreement is intended to pivot Q-SYS' focus onto intelligent video collaboration based in the startup's computer vision, machine learning, and scene perception expertise.
