THAILAND: Thailand’s Huayrai Eleena Chill #1 festival in Sakon Nakhon Province has delivered a defining moment for large-scale live sound in the country, becoming both the second deployment of the Adamson Vergence Group in Thailand and the first time the system has been rolled out in its complete configuration. Staged at Huayrai Arena and organised by Kong Huayrai, the event embraced a laid-back, open-air concept designed for relaxed music enjoyment—yet behind the scenes, the production represented a highly technical milestone for Adamson and its official Thai distributor, Sonos Libra.

Sonos Libra partnered with local rental specialist Team Creation to design and implement the audio system, specifying an Adamson Vergence Group configuration that combined VGt line array loudspeakers with VGs subwoofers to deliver maximum power, precision and impact across the festival site. The collaboration followed the success of the Nakhon Nan Music Festival the previous year, which had marked the first VGt deployment in Thailand and demonstrated the system’s potential. That earlier experience led the organiser to once again entrust Sonos Libra with the audio design for Huayrai Eleena Chill #1—this time for a full-scale implementation.

Preparation proved to be a decisive factor. Sonos Libra’s engineering team developed detailed system diagrams and user data sheets and distributed them to the rental crew in advance, ensuring that the installation process would be both efficient and accurate. On arrival at the venue, the entire system had already been rigged using Adamson’s AutoLock rigging system, highlighting both the clarity of the pre-production planning and the intuitive nature of the hardware itself.

The main PA comprised a total of 16 units of the VGt loudspeakers supported by 16 ground stacked units of the VGs subwoofers to deliver authoritative low-frequency performance. Front-fill coverage was provided by 10 units of the CS7 units, while two CS10p and four CS119 loudspeakers were deployed as stage side fills, ensuring consistent sonic coverage across the audience area and performance zones. Although the system’s initial height, angles and coverage had been modelled using Adamson’s ArrayIntelligence software, the final configuration was refined on site through listening tests. Subwoofer arrangements were adjusted, array angles and trim heights were fine-tuned, and the overall system tuning was optimised to preserve Adamson’s signature sonic character while accommodating the musical styles of the artists performing at the festival.

At front of house, the system was driven by an Allen & Heath dLive DM48 as the main mixing engine, operated via an S5000 surface and interfaced through a DirectOut PRODIGY.MP to convert Dante signals to Milan AVB. This signal path enabled seamless integration with the Adamson loudspeaker system through three Adamson CS-Racks, forming a robust and fully redundant architecture designed to guarantee operational stability throughout the event. System performance and sound pressure levels were continuously monitored using Rational Acoustics Smaart Suite in conjunction with Earthworks Audio M30 measurement microphones, allowing real-time optimisation and consistent control of overall system behaviour.

For Team Creation, Huayrai Eleena Chill #1 represented a first encounter with the Adamson Vergence Group, yet the installation process proved straightforward. The crew reported that the AutoLock rigging system made handling and deployment intuitive, enabling them to execute the build efficiently despite the scale and complexity of the configuration. From an engineering perspective at FOH, the experience further reinforced the system’s capabilities. Having previously mixed on a VGt-only deployment at Nakhon Nan, the front-of-house engineer noted a clear step change in performance with the full Vergence Group, particularly in the depth, power and impact of the low end delivered by the VGs subwoofers, alongside the clarity and transparency of the main arrays.

As both a technical achievement and a statement of intent, Huayrai Eleena Chill #1 underlined the growing sophistication of Thailand’s live event production landscape. For Adamson and Sonos Libra, the festival demonstrated not only the scalability and sonic authority of the Vergence Group, but also the value of meticulous system design, advanced signal integration and close collaboration with local production partners. In delivering a world-class audio experience within a relaxed, festival setting, the deployment marked a significant step forward for high-performance touring sound in the Thai market.
