    L-A2 Features
    Dedicated for 100/70V line amplifiers

    The L-A2 is optimized for the specific requirements for 100/70V line applications. This is evident in the high voltage rails providing direct drive. Energy Star compliance compulsory in many tenders. Extensive protection scheme to protect against fault scenarios during system installation.

    2RU rack installation

    The minimal physical dimensions of the L-A2 module gives a dedicated 100/70V line amplifier solution with integrated power supply and direct drive capability that fits into a 2RU rack. Combined with the L-PRO2S module, it is possible to design multi-channel 100/70V systems with small external dimensions.

    Audiophile Performance

    Pascal’s proprietary UMAC™ Class-D technology delivers unequaled audiophile specifications, including the highest dynamic range and the lowest distortion performance of any comparable pro audio amplifier. This makes the L-PRO2S 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 and U-PRO Series, the L-PRO2S 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-PRO2S 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-PRO2

    The L-PRO2S 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-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.
