Kairos Multi Jaya Hosts “Symphony of Resonance” – Showcasing TT+ Audio GTX Series for a Real-World Festival Audio Experience

Held at Gambir Expo, JIEXPO, Jakarta, a venue widely recognized for hosting top-tier festivals in Indonesia, the event gathered dealers, rental partners, and system integrators from across the country. The location was strategically selected to represent a live production environment, where high-performance systems are required to deliver consistent coverage, high SPL, and sonic accuracy across large audience areas.

The event also received strong institutional support, marked by the presence and welcoming
remarks from Assistant to the Governor (Sekda) of DKI Jakarta for Education and Public Welfare, Mayor of North Jakarta, and Vice Mayor of East Jakarta—highlighting the growing role of the professional audio industry within Jakarta’s creative and cultural infrastructure.
Prior to the main demonstration, attendees were guided through a structured pre-show experience.

The “Legacy Walk” showcased the long-standing collaboration between RCF and Kairos Multi
Jaya. This was followed by an interactive Experience Booth, where visitors engaged directly with selected RCF systems—including KX 08-A, KX 10-A, NXL 44-A, SUB 9019-AS, and SUB 9029-AS—within a hands-on evaluation environment that enabled critical listening and real-use
workflow simulation, from exploring system voicing to performing live mixing for keyboard and
DJ applications.

At the core of the demonstration was a full-scale deployment of the TT+ GTX system, featuring
GTX 10 and GTX 12 modules configured with nine units per side (L/R). The system was supported by GTS 29 subwoofers deployed in five stacks of three units each and arranged in a cardioid configuration to ensure controlled low-frequency directivity and minimal stage spill. The entire system was externally powered and managed via the XPS 16K platform—a high-performance 4-channel amplification and control system designed to drive both tops and subwoofers—offering high headroom, low distortion, reduced cabling, and faster deployment, making it highly efficient and scalable for high-end touring and large-scale festival applications.

The program opened with a technical presentation led by Yannick Dahms, TT+ Audio Product
Specialist, together with Karuna Madhusudana Atmaja (Supervisor Audio Engineer, Kairos Multi
Jaya), covering the evolution from RCF to TT+ and an overview of the GTX Series, its design and touring applications, alongside system design, software integration, and workflow for prediction and optimization in live production environments, followed by playback sessions demonstrating precise instrument separation, controlled low-frequency extension, and consistent spatial imaging across a wide coverage area—maintaining tonal balance and detail even at high output levels, without the use of additional EQ processing—while attendees were also invited to access the FOH position to observe, evaluate, and directly experience the system performance in real time.
“Events like Symphony of Resonance are extremely valuable because they allow professionals to evaluate the GTX Series in a real production context, not only in a controlled demo environment,” said Yannick Dahms, TT+ Audio Product Specialist. “Kairos Multi Jaya organized the program with great care and professionalism, creating the right conditions for dealers, rental partners, system integrators, and audio engineers to experience the system at scale. We are grateful for their commitment and proud of the strong partnership that continues to support the growth of RCF and TT+ Audio in Indonesia. It is also an honor to see how much the Indonesian market values RCF technology, engineering, and sound quality.”
The demonstration concluded with a live drum performance by Amos Cahyadi, a living legend of
Indonesia’s drumming scene, pushing the system through a wide range of musical dynamics—from rock and ballad to progressive and technical solo performance. The system exhibited tight and controlled low-end response under high SPL conditions, articulate and detailed midrange within dense mixes, and fast transient response required for modern live applications. Throughout the performance, the GTX Series maintained clarity, dynamic integrity, and consistent tonal balance across the entire audience area. The program then continued with a live band performance, showcasing system versatility across full arrangements, while maintaining focus on the transient response and dynamic integrity highlighted in the drum session.

Beyond the technical demonstration, “Symphony of Resonance” also served as a platform for
industry engagement, combining product exploration, application insight, and networking within
Indonesia’s professional audio ecosystem.

“Symphony of Resonance reflects our vision to elevate live sound standards in Indonesia through a true live production environment, enabling invited audio professionals to directly experience system performance in real conditions and setting a clear reference for high-performance applications at scale,” said Martin, Director of Operations, Kairos Multi Jaya.
Through this initiative, Kairos Multi Jaya continues to strengthen its role in advancing professional audio standards, aligning technology, application, and industry needs within Indonesia’s evolving live event landscape.
