Pascal’s new amplifier module optimised for self-powered portable PA and fixed install applications


Pascal A/S Copenhagen, Denmark. Pascal has announced the launch of its new U-PRO Series amplifier module. A design uniquely optimized for self-powered portable PA systems and ultra-compact, high SPL loudspeakers for fixed installation applications; offering both single and asymmetrically rated 2-way power channels.

The U-PRO series features unique dynamic power ratings, due to its extremely high voltage rails, relative to its RMS power output. Resultantly, with RMS ratings of 280 W, it can deliver ultra-short bursts of 500 W RMS or 1000 W peak power; at a lower cost point than normal market expectations for such power capabilities. These are optimal performance characteristics for lightweight portable PA and ultra-compact, high output fixed install cabinet designs.

The U-PRO2 has a 280 W + 100 W two channel asymmetrical power rating for 2-way loudspeaker cabinet designs, while the U-PRO1 provides a single channel of 280 W – into 4 ohms. At just 38 x 70 x 177 mm / 1.5 x 2.5 x 7.0 in, the U-PRO module has the smallest form factor, lowest profile and highest power density of any comparable product of this type.

The U-PRO’s performance characteristics uniquely match the power requirements for cost effective, high SPL self-powered portable PA. This rapidly developing product class employs cost optimized drivers that can handle high SPL peaks but have limited long-term power handling capabilities. U-PRO’s singular dynamic power configuration delivers high, non-clipping, short power bursts of up to 500 W and peaks of up to 1000 W.

In both BGM and ancillary fixed install applications, the U-PRO is optimally specified to meet the growing demand for self-powered, ultra-compact and visually unobtrusive, high output loudspeaker designs. The high dynamic power ratings of the U-PRO, relative to its ultra-compact form factor and coupled with its low residual noise, are unique in a design of such high sonic quality. The amplifier’s residual noise floor is inaudible in the lowest ambient noise environments, such as theaters, concert halls and auditoria. Applications where its audiophile credentials, including the highest dynamic range and power density, and lowest distortion of any comparable pro audio amplifier, give it a clear performance advantage.
Pascal’s UREC™ PFC (Power Factor Correction) power supply technology enables universal AC mains operation, delivering consistent, regulated power worldwide and eliminating susceptibility to local power related reliability issues. The U-PRO Series also boasts the world’s best system efficiency, minimizing the requirement for heat sinks and cooling, and contributing to the amplifier’s long-term reliability.

Supporting modern connectivity requirements, an auxiliary power feed is available for integrated DSP, network or analog I/O boards. Readouts of protect/mute, temperature and clip signals are accessible for DSP and network or wireless control implementations, and I/O stages. The U-PRO Series features ultra low standby power consumption for EuP2013 and green energy star compliance, with an Auto Standby/Wake-up feature with selectable time settings, making the module ready to handle future regulatory requirements.

Speaking on the launch of U-PRO Series, Senior VP of Business Development, Peter Frentz said, “Pascal is at the forefront of understanding of and insight into, the future requirements of the professional audio market, in terms of the specific application demands for self-powered amplification. Our dedicated designs deliver a performance premium not available from general-purpose, commodity products.

“Our advanced engineering of the specific performance requirements for distinct applications allows us to design a product like the U-PRO series, able to deliver optimum performance specifications for two distinct applications that demand those same specifications for different ends. It is this vision and engineering premium that sets Pascal apart, and makes us the ‘go to’ supplier of amplifiers for self-powered loudspeakers, enabling manufacturers to achieve ever increasing performance, efficiencies, faster time to market and cost competitiveness.”
