    Flexible Power Configuration

    Pascal S-PRO Series amplifier modules provide a flexible power platform for 1-4 channel configuration. The possibility to configure the power asymmetrical
    makes it especially ideal for selfpowered loudspeaker applications where you need the most power for the LF sec

    Unmatched Sonic Performance

    Thanks to Pascal’s proprietary UMAC™ Class-D technology, Pascal amplifier modules deliver unmatched audio specifications. The UMAC™ technology ensures Pascal amplifier modules offer the highest dynamic range and the lowest distortion in the pro audio industry.

    Universal Mains & PFC

    Pascal’s UREC™ PFC (Power Factor Correction) power supply technology provides universal mains operation, eliminating the need for market specific products and related reliability issues. The power supply is regulated, delivering consistent power world-wide.

    Ultra Compact, Ultra Efficient

    The S-PRO Series is the most compact +1000 W amplifier modules in the world, making it possible to integrate in ultra compact chassis or trapezoidal loudspeaker cabinets. Furthermore, the S-PRO Series boast of the world’s best system efficiency, thus minimizing the need for heatsink and cooling.

    Auxiliary Power & Readouts

    Auxiliary power is available to power DSP- or analog input cards. In addition readouts of protect/mute, temperature and clip are accessible for DSP/Network or IO-boards. The S-PRO Series features ultra low standby power consumption for EuP2013 and green energy star compliance.

    Safety Approved - EMC Compliant

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