  • LA108/LA112 User Interface

    In this section we dive into the Rear User Interface (RUI) menu featured on the LA108 and LA112 active loudspeakers. You'll learn to navigate the simple interface using he onboard controls and get familiar with the entire menu system. 

  • RapidDeploy™

    In the video we explain and demonstrate the unique an innovative QSC RapidDeploy rigging system featured on the LA108 and LA112 loudspeakers. 

  • Array Frame Deployment

    In this section we cover the deployment of an L Class line array in a flown configuration using the L Class Array Frame. Learn the proper procedures for setting up, adjusting angles and tearing down an array. 

  • Ground Stack Deployment

    In this section we'll cover the ground stack deployment of an L Class line array using the array frame over the LS118 subwoofer. 

  • Pole Mount Deployment

    In this section we show you how to deploy a small number of LA108 or LA112 loudspeakers on a loudspeaker stand or on an extension pole above a subwoofer. 

  • AWARE™

    In this section we dive into the intelligent, onboard QSC AWARE™ system that communicates essential setup information to the user via any loudspeaker's Rear User Interface (RUI) or QSC SysNav App and allows the user to optimize the array in any configuration to consistently get the best performance out of your L Class system.

  • System Navigator (SysNav) App: Connecting to the system

    In this module, we'll take our first look at System Navigator (SysNav) App. SysNav is a complete control and monitoring software application for an L Class system. We start out by going through the process of downloading and installing the application on on iPad or Windows PC before proceed to demonstrate making a successful connection to an L Class system.

  • SysNav App: Controlling and monitoring an L Class system

    In this module we demonstrate how to control an L Class system using the "Control" module within SysNav as well as how to access the various monitoring screens for real time system telemetry.

  • SysNav App: Using the AIM module

    In this module we walk though the AIM module within the System Navigator application. The AIM module offers pre-deployment visualization of the acoustic coverage of an L Class system. This video discusses how to add venue parameters within the software and populate an L Class line array system to be modeled.
