    U-PRO2 Features
    Extreme Dynamic Power Ratings

    The U-PRO series features unique dynamic power ratings, due to its extremely high voltage rails relative to its RMS power output. Resultantly, with LF channel RMS ratings of 280 W, it can deliver ultra-short bursts of 500 W RMS or 1000 W peak.

    U-PRO2 Dedicated for 2 Way Speakers

    The U-PRO2’s asymmetrical power configuration, feature set and form factor uniquely optimize it as a dedicated power solution for self-powered 2-way loudspeakers.

    Audiophile Performance

    Pascal’s proprietary UMAC™ Class-D technology delivers unequalled audiophile specifications, including the highest dynamic range and the lowest distortion performance of any comparable pro audio amplifier. This makes the U-PRO series suitable for pro audio applications and for use in high-end Hi-Fi and AV products.

    Universal Mains & PFC

    Pascal’s UREC™ PFC (Power Factor Correction) power supply technology enables universal AC mains operation, eliminating the need for local market specific power regulation products and susceptibility to related reliability issues. The power supply delivers consistent, regulated power worldwide.

    Unmatched Efficiency

    Like the S/T & L-PRO Series, the U-PRO2 Series boasts the world’s best system efficiency, minimizing the requirement for heat sinks and cooling. The cool operation also contributes to the amplifiers’ long term reliability.

    Auxiliary Power & Readouts

    Auxiliary power is available for DSP or analog I/O cards. Readouts of protect/mute, temperature and clip signals are accessible for DSP/Network or IO-boards. 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.

    Interface compatible with T-PRO, S-PRO and L-PRO

    The U-PRO2 Series features compatible pin interfacing and identical output voltages to the higher current capable, popular S-PRO, T-PRO and L-PRO modules; thus the front-end electronics of both the S-PRO, T-PRO, L-PRO and U-PRO2S Series are plug-and-play compatible.

    Safety Approved - EMC Compliant

    Pascal amplifier modules are safety approved and verified for EMC compliance. CB report and UL certificates are available for easy market approval.
