My Hair is Bad wraps tour with L-ISA shows
- Details
The band’s sound engineer, Hironori Ochi had first learned of L-ISA technology from Masaaki Nagayasu, systems engineer at L-Acoustics certified rental agent Hibino Sound, who hosted Mr. Ochi to an L-ISA workshop in his personal studio. On discovering the capabilities of L-ISA, Mr. Ochi began working on the design of an L-ISA Hyperreal Sound system for the 10,000-capacity Osaka-Jo Hall arena concert.
“I received L-ISA training with L-Acoustics in the spring of 2022. The impact of the pandemic meant that it would be some time until I could work on an L-ISA concert. When Ochi approached me with the My Hair is Bad concert project, I felt confident that this would be the right one, at the perfect time to introduce L-ISA to live music fans in Japan," explains Mr. Nagayasu.
After informing the production team that the concert would be presented in immersive audio, Mr. Nagayasu considered technical specifications for a system design that would adhere to loading and rigging limits of the venue.
The final L-ISA configuration consisted of a main Scene System of five hangs of 12 L-Acoustics K2 each. A cluster of 12 KS28 subwoofers was flown just behind the main Scene System. Out-fill consisted of 15 Kara II per side while 11 L-Acoustics A10 Focus served as front-fill. Six KS28 subwoofers were also evenly distributed across the front of the stage to provide more low-end rumble to the concert arena. Forty LA12X amplified controllers drove the entire system.
The L-ISA Processor II received MADI signals from a DiGiCo SD10 mixing board via Luminex GigaCore while an L-Acoustics LS10 distributed audio and control signals over Milan AVB. Mr. Nagayasu calibrated the system using an L-Acoustics P1 AVB processor.
“It was a very enjoyable experience for me to mix on L-ISA. We took advantage of its capabilities and presented the music in a new way for the fans and concert goers,” says Mr. Ochi. “As the lights came on after the encore, the audience had smiles of delight and praise for the sound team.”
