    L-PRO2HP Features
    Ultra High Power and Self-Protected

    The L-PRO2 series feature high power levels for
    speaker system requiring very high SPL. Moreover
    the L-PRO2 series is equipped with protection features
    making them fully self-protected and designed
    after and audio-at-all-times principle.

    Dedicated for Speakers & Subwoofers

    The L-PRO2 and L-PRO2HP asymmetrical power configuration,
    feature set, and form factor uniquely optimize
    it as a dedicated power solution for self-powered
    2-way loudspeakers. The symmetrical output
    channels of the L-PRO2S makes it convenient for selfpowered

    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 L-PRO2 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 & U-PRO Series, the L-PRO 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 L-PRO2 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 S/T/U-PRO

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