Powersoft T Series Elevates Vietnam’s Premier Rooftop Venue Sky-Bar

Situated atop the four-star Premier Pearl Hotel in Ba Ria Vung Tau, Vietnam is a buzzing rooftop hotspot called Sky Bar that has emphatically has raised the bar for high-performance sound in coastal entertainment venues with the installation of Powersoft’s robust and compact T Series amplifiers. The venue now combines panoramic sea views with an audio experience tailored for high-energy nightlife and dynamic live events.

To achieve the desired sound pressure and fidelity in a challenging coastal environment, Hoang Phu Sound led the project as both integrator and consultant. Working in collaboration with Universal Procurement Systems Vietnam Co. Ltd (UPSV), Powersoft’s local distributor, the team deployed one Powersoft T904A and two T604A amplifier platforms — compact four-channel units rated at 8000W and 6000W respectively — to deliver a powerful, clean and efficient sound system that matches the venue’s vibrant atmosphere.

“The T Series offered a compact size with powerful performance, which was perfect for Sky Bar,” said Nguyen Luong Niem, Technical Manager at UPSV.

Installed centrally behind the bar for ease of access and monitoring, the amplifiers are paired with Bose Professional AMU208 full-range loudspeakers and MB210WR subwoofers, configured in bridge mode through the T604A units. System configuration and tuning were carried out using Powersoft’s ArmoníaPlus System Design software, enabling precision adjustments and real-time performance optimisation. “ArmoníaPlus software allowed the team to configure and fine-tune remote adjustments with ease and efficiency while ensuring that the system performed optimally,” added Niem.

Durability and long-term reliability were key considerations for the Sky Bar installation, which is exposed to the harsh seaside elements of wind and airborne salt. The T Series’ solid design, coupled with its five-year warranty, helped fulfil both acoustic and environmental demands. “Before using Powersoft, we faced issues with inefficient energy usage and heat dissipation in large sound systems, especially in high-demand environments,” Niem explained. “After switching to Powersoft’s T Series, these issues were resolved with the help of Powersoft’s Smart Rails Management technology, which recycles reactive energy and reduces heat dissipation while also improving energy efficiency.”

Sky Bar’s sound system was expected to deliver clarity and punch to support live DJ sets and music-driven events. Working with limited rack space, tight project timelines and equally demanding acoustic expectations; the compact form factor and high output of the T Series were especially advantageous. “This sound system required high volume, powerful bass and clear mid-highs due to the involvement of DJs,” said Niem. “Powersoft’s T Series offered the perfect solution thanks to its compact size and robust power output.”

Despite the technical and environmental challenges, the completed installation has earned praise from both the client and venue patrons. “Powersoft’s amplifiers provided the team with stable amplification, ensuring perfect sound performance at all times,” Niem stated. “The end user is extremely happy with how the system has transformed the Sky Bar experience, making it more engaging and enjoyable for guests.”
