KLANG Announces KOS 6.1: Reverb Gives In-Ear Mixes a Space of Their Own

KLANG:technologies has introduced KOS 6.1, the latest update to its operating system and KLANG:app, bringing new features designed to improve in-ear monitoring for musicians and live sound professionals. The update introduces individual reverb for every mix, allowing musicians to choose from four reverb types: Room, Hall, Cathedral, and Plate. With adjustable settings for each mix, monitor engineers can create a more natural listening experience while helping musicians maintain clarity at lower listening levels.

KOS 6.1 also adds a safety limiter to protect musicians from sudden audio spikes and an ambience ducker that automatically manages audience microphone levels between performances. Other improvements include smoother backup switching for redundant DiGiCo systems, easier network management, and Dante patching for KLANG:vokal through KLANG:app. Available as a free public preview for eligible KLANG processors and controllers, KOS 6.1 is expected to become the official release by the end of November.

KLANG:technologies announces KOS 6.1, the latest update to its operating system and KLANG:app, which gives every mix its own reverb. The update also adds a safety limiter and an ambience ducker to KLANG:kontroller.

“Reverb has long been one of the most requested features from musicians and monitor engineers,” says KLANG Co-Founder Dr. Pascal Dietrich. “Immersive mixing has already taken away the isolation musicians used to feel on stage, and spatial positioning has let them turn their in-ears down without losing detail. Now, with KOS 6.1, every mix gets a room of its own, running directly on the processor: a singer can hear their voice in a cathedral while the drummer keeps a tight room around the kit. Add a safety limiter that is on before anyone has to think about it, and you get exactly what KLANG has always stood for: lower levels, better mixes.”

Free of charge, the new reverb runs directly on the KLANG:konductor, KLANG:vokal, DMI-KLANG, and KLANG:1pro processors. Every mix can choose from four reverb types—Room, Hall, Cathedral, or Plate—each with its own adjustable time, return level, and four-band EQ. A reverb send on every channel lets the vocal sit in the room while kick drum and bass stay dry.

Monitor engineers set up each mix’s reverb in KLANG:app, and musicians can adjust their own reverbs on KLANG:kontroller or in KLANG:app. Existing shows load with the reverb off, so updating never changes a mix that’s already signed off.

Immersive mixing already lets musicians hear every source clearly at a lower volume, because instruments no longer mask each other in the middle of the head. A room around the mix makes it sound even more like a real stage, so there’s less reason to push the level up to feel the music.

KOS 6.1 also brings a new safety limiter and an ambience ducker to KLANG:kontroller. The safety limiter is on by default and protects the musician’s ears by catching sudden full-scale bursts, such as a dropped cable or a feedback spike, before they reach the in-ears. The ambience ducker lowers the audience mics while the band plays and brings the crowd back between songs.

In redundant DiGiCo systems, every KLANG:kontroller and KLANG:app now follows the console; one macro, or the console’s own switch to its backup engine, moves them all to a backup KLANG processor, each musician on their own mix. Without a DiGiCo console, one Action Button in KLANG:app does the same.

Ultimately, KOS 6.1 makes KLANG smoother every day: easier to set up, faster in operation, with network switches that list every KLANG unit by name and port, and Dante patching for KLANG:vokal right from KLANG:app.

KOS 6.1 is available now as a free public preview for all eligible KLANG processors and KLANG:kontrollers. To ensure continuity for active productions, the preview comes first: KOS 6.1 will replace the current KOS 6.0 as the official release by the end of November.
