The Future of Live Sound — Smarter, Faster, and Easier Than Ever
In professional sound reinforcement, precision, power, and reliability define success. QSC’s L Class loudspeakers are designed to deliver all three — with next-generation performance, intelligent networking, and exceptional ease of use. At the center of it all is Sysnav, the intuitive software that gives engineers total command over every L Class system.
What Is Sysnav?
Sysnav is QSC’s dedicated software platform for configuring, controlling, and monitoring the L Class series of active loudspeakers and subwoofers. Built for speed, flexibility, and confidence, Sysnav makes it simple to deploy, tune, and manage even the most complex sound systems.
From LA108 and LA112 active line array loudspeakers to the LS118 active subwoofer, Sysnav recognizes and connects each component automatically, ensuring your system is ready to perform within minutes.
Effortless Setup and Mounting
QSC designed the L Class not only for superior sound but also for unmatched ease of deployment. The system’s QuickLock™ rigging mechanism allows single-person setup, reducing load-in time and eliminating the frustration of complex hardware.
Arrays can be assembled on the ground and flown safely with minimal tools, while ground-stacked configurations lock securely and align perfectly every time.
Sysnav complements this hardware innovation by detecting rigging configuration automatically and applying optimized presets for coverage and tonal balance — ensuring your system sounds perfect right from the first note.
Intelligent Design Meets Intuitive Control
With its clear graphical interface, Sysnav provides a visual layout of your loudspeaker system, giving you precise control at a glance.
- Automatic array configuration for fast deployment
- Real-time monitoring of input levels, temperature, and amplifier health
- Network-based control via standard Ethernet connections
Whether you’re managing a festival main stage or a corporate AV install, Sysnav ensures every element performs flawlessly.
Advanced System Optimization
Sysnav unlocks the full potential of QSC’s powerful onboard DSP with tools like:
- Custom EQ and gain shading per loudspeaker or group
- Delay alignment for perfect phase coherence
- Coverage prediction and tuning aids
The result is pristine, consistent sound — no matter the size or shape of the venue.
Designed for the Modern Audio Professional
Between Sysnav’s intelligent control and the L Class’s smart mechanical design, QSC delivers a system that’s fast to deploy, easy to manage, and ready for anything. Less time configuring and mounting means more time mixing, performing, and impressing your audience.
Elevate Your Sound with Sysnav and L Class
Together, Sysnav and the L Class ecosystem redefine what’s possible in professional sound. From effortless setup to intelligent control and stunning sonic performance, this is the future of live sound — made simple.
