Grande Centre Point Lumphini r partnered with Mahajak Development, to integrate an advanced Harman Professional system, featuring JBL Professional, Crown, BSS, Martin, and AMX technologies, to establish a unified system spanning two floors and nine event venues.
In its fourth project with the hotel, Mahajak Development delivered the complete design and installation of a fully integrated AVL and control system for the hotel’s function spaces, meeting facilities, and public areas, creating a professional-grade and flexible environment capable of supporting corporate meetings and conferences to large-scale banquets and special events.
The design centres on a consistent audio and control experience across all rooms, with each space equipped according to its function and seating capacity. A combination of 24 JBL SRX910 line arrays and 12 SRX928S subwoofers provides the primary FOH reinforcement, ensuring consistent performance from keynote sessions to gala dinners. To expand configuration flexibility, the hotel also deploys 24 JBL BRX308-LA line arrays and 8 BRX325SPS subwoofers, enabling teams to adapt FOH setups to different room layouts and audience sizes while maintaining a uniform JBL sonic signature.
Crown CDi 4|300 amplifiers and BSS BLU-806DA processors provide precise routing and tuning for the larger function spaces, while meeting rooms use JBL Control series ceiling loudspeakers, such as the Control 16C/T, Control 18C/T and Control 47LP, paired with Control 19CS ceiling subwoofers for speech clarity and even coverage.
BSS processors serve as the backbone for signal management throughout the property, providing room-by-room routing, preset control and system optimisation. Crown CDi amplifiers deliver consistent amplification across all zones.
Beyond the meeting suites, distributed audio is provided through over 95 JBL Control series speakers and 16 JBL GSF6 ground-stake landscape loudspeakers. These deliver coverage across lobbies, pre-function zones, fitness areas, and public corridors. The system is powered by nine Crown CDi 4|300 amplifiers and managed by two BSS BLU-806DA and 2 BSS BLU-100 processors. For flexible reinforcement, two JBL PRX ONE powered column PA systems are available for pop-up presentations and smaller activations.
To give hotel staff a cohesive and accessible control environment, the property also implemented four AMX NX-2200 control processors with eight AMX Varia-SL80 wall-mounted touch panels and four AMX TCP-IPAD control licenses for unified operation.
During design and commissioning, JBL Venue Synthesis and JBL Performance Manager were used to model room acoustics, optimize loudspeaker placement, and fine-tune system performance.
Mahajak also installed eight Martin MAC Aura PXL fixtures, delivering immersive wash lighting with detailed pixel-mapping effects, as well as four Martin ERA 150 Wash fixtures, providing illumination suitable for conferences, banquets, staged presentations, and more.
Nick Screen, sales lead for Harman APAC, commented: “Grande Centre Point Lumphini wanted a sound system that would be as flexible and refined as the experiences they offer. The Harman Professional solution ensures every guest—from those attending a conference to those relaxing in a lounge—hears clear, consistent sound across the hotel.”
