Take the Lead in Acoustics with COMSOL Multiphysics®
audioXpress|December 2022
Multiphysics simulation drives acoustics innovation by providing insight into every design aspect that influences product performance. The ability to account for coupled physics phenomena lets you predict, optimize, and virtually test a design under realworld conditions - even before a first prototype is built.
Take the Lead in Acoustics with COMSOL Multiphysics®

Q-LAN and Q-Sys quickly expanded to cover all the applications that QSC embraced, from portable PA systems and DSP amplifiers, to its prestigious Cinema systems. More important, Q-SYS enabled QSC to grow into the installation business, from commercial audio to meeting room solutions. Particularly since the acquisition of Attero Tech in 2019, QSC was able to grow its audio, video, and control networked ecosystem, while also boosting QSC's development capabilities with Attero Tech's Fort Wayne, IN-based engineering staff.

Today, the Q-SYS business division offers a complete cloudmanageable, software-driven audio, video, and control platform supported by a vast partner ecosystem. Its range of products includes Q-SYS Core Processors, NV Series and SPA-Q Series/CX-Q Series amplifiers, Acoustic Design Series loudspeakers, Q-SYS software licenses, Cinema products, and more.

Never Mind the Standards. Where's the Chips?

In 2020, the installation sector was excited and supportive of some of the open standard efforts and specifications promoted by industry alliances, and the convergence of industries. Also of note, commercial and residential installation sectors were at the forefront of exciting innovations in terms of networking, signal processing, and control, benefiting from the convergence with cutting-edge professional audio and consumer technologies.
