- Iconic America venue, the Hollywood Bowl in Los Angeles, has upgraded its sound system
- New line array is the L1 from L-Acoustics
- New machine learning L-Acoustics application, Source Intelligence, is in use which continuously identifies and isolates voices from microphones to remove other noise.
Source Intelligence, L-Acoustics' proprietary voice-separation technology, is now in use at one of America's most iconic venues, the Hollywood Bowl.
Running as an exclusive licensed application on the L-ISA Processor II and fully integrated in the L-Acoustics system workflow, Source Intelligence uses machine learning to continuously identify the voice in a microphone signal. The tool removes everything else including band instruments and crowd noise, preserving the natural tone and clarity of the voice.

Source Intelligence was unveiled by Laurent Vaissié at the L-Acoustics keynote at the Holly Wood bowl earlier this spring.
“For decades, engineers have been solving the PA bleed and feedback problem with compromises like notch filters that color the sound, expanders that can be unpredictable, or staging layouts that pull performers away from the audience,” explains Ryan John, Director of Product Management, Software at L-Acoustics. “Source Intelligence removes that trade-off entirely. The machine is continuously listening and continuously working, so the engineer can focus on the mix instead of fighting feedback, and the performer can own the whole stage.”
- In blind listening tests Source Intelligence consistently ranked highest for voice quality among competitors, removing up to 40 dB of non-voice signal.
- The technology also significantly reduces feedback risk by eliminating the PA bleed and ambient noise that cause it.
- Source Intelligence has been used in the field since Spring 2025 across major touring productions, Broadway shows, and key house-of-worship campuses.
- Current beta partners include: Solotech on the Harry Styles tour, Clair Global on Benson Boone and Rosalia tours, and PRG on the Broadway production Dog Day Afternoon.
- The technology is designed for any application where a voice is being amplified: touring, house of worship, corporate events, and theatrical productions.
- Source Intelligence is part of a growing portfolio of licensed technologies that run on the L-ISA Processor II as part of the full L-Acoustics ecosystem, the same platform that powers L-ISA Immersive Hyperreal Sound, L-Acoustics DJ, Ambiance, and HYRISS.
- Once installed, Source Intelligence requires no threshold setting, no ongoing adjustment, and no changes to the existing console workflow or signal routing.
- End-to-end latency is less than 8.5 ms over MADI, fixed whether processing is active or bypassed, so that automation and snapshot changes never affect system timing.
“Source Intelligence gives me a vocal sound like no other. It’s basically studio quality vocals now, which changes the game completely,” says Joey Diehl, FOH engineer for Benson Boone.
“I’m very impressed with how much headroom it gives me. I was able to get crisp, clean vocals in any scenario—including very loud stage environments and actors in front of the PA,” says Cody Spencer, Tony Award-winning sound designer who used it on the Broadway production Dog Day Afternoon.
In addition to Source Intelligence, the upgrade at the venue includes the L1 line array system, with reshaped cabinets angled to reduce the footprint but more powerful to reach the outer seating areas.
