Malaysian alt-rock band Hujan is one of the country’s most influential contemporary acts with following across the region. The recent Atas Angin Festival saw the band deploy the Sennheiser Spectera wideband wireless ecosystem that is now central to their touring infrastructure, serving musicians, engineers and crew within a single wideband RF environment.
Fronted by Noh Salleh, Hujan continues to evolve creatively while preserving the raw energy that they has when formed in 2005. The band first introduced Spectera at Rock In The Jungle 2.0 at Sarawak Cultural Village in August 2025, marking their move from renting Sennheiser’s IEM G4 in-ear monitors to a fully integrated wideband ecosystem.
Under the guidance of band manager Ariffin ‘Epain’ Ahmad, Hujan have invested in a Spectera set-up comprising Base Station, two DAD antennae and 12 SEK bodypacks. These are distributed across the team – four for band members, two for sessionists, one each for monitor engineer Zunnun Zolaznan and RF engineer Amir Shah,and four for crew.
‘From the very first demo, we knew Spectera was operating on a different level,’ says Epain. ‘The set-up was intuitive, the audio refined, and the system felt future-ready. Our decision was strengthened by the trust we have in Sennheiser and Acoustic & Lighting System, particularly their technical support.’
At Rock In The Jungle 2.0, the deployment transmitted audio and control signals via a single wideband RF channel. Consolidating every link into one coordinated spectrum block eliminated the need to manage multiple narrowband frequencies, simplifying RF coordination. ‘Managing one wideband channel reduces complexity and frees us to focus on optimisation rather than troubleshooting,’ says RF engineer Amir Shah. ‘Even with all users active across stage and backstage, oversight remained straightforward.’
At Atas Angin Festival 2026, the same wideband configuration was deployed successfully, reinforcing Spectera’s consistency and reliability across different festival environments. Monitor engineer Zunnun Zolaznan noticed the difference from the first soundcheck: ‘The sound was open, clear, and highly detailed. Since the signal path is so clean, I don’t need heavy processing to create separation. The result is a more organic and transparent mix,’ he says.
He also highlights how ambience is perceived through the Spectera IEMs: ‘The ambience sounds natural and spacious. It’s not just a loud, generic sound; it’s detailed and clear. That sense of depth enhances the band’s connection to the crowd. And managing a single RF channel for all users makes oversight much easier.’
‘This confidence transforms the entire production,’ Epain notes. ‘Artists and technicians can hear every nuance clearly. The assurance that the system will remain stable removes a significant layer of stress. Sennheiser’s support was professional and comprehensive, making the transition seamless.’
FOH engineer Ahmad Syafiq highlights Spectera’s impact on overall production: ‘What stood out immediately was how quickly the system could be deployed and how expansive the soundstage felt. In terms of audio integrity, RF stability, and deployment speed, it surpassed everything else we evaluated.’
Although in-ear monitoring does not directly alter the FOH mix, its impact is felt throughout the production. ‘When the band performs with confidence and precision, it elevates the entire show. The performance feels tighter and more refined for the audience. The WebUI provides an impressive depth of information for RF management, streamlining workflow across all connected SEKs,’ he adds.
‘We intend to continue building our shows around Spectera,’ Syafiq says, looking ahead. ‘The Sennheiser team and Acoustic & Lighting System have been invaluable partners for a product that represents a major technological advancement.’
What began as a strategic investment in 2025 has become foundational to Hujan’s live production. Spectera has proved itself as a consistent and reliable system, enhancing on-stage clarity, simplifying RF management and giving operational confidence – returning to their previous set-up is no longer under consideration.
