        Product details

        Hypex FA500 2x500 +100 Watt FusionAmp


        Due the combination of SMPS, DSP and Ncore based amplifiers packed in this plate amplifier, FusionAmp is one of the best amplification solutions available for active speaker designs. The integrated DSP provides great audio processing functionality. Thanks to the Ncore technology distortion (THD and IMD) over the full audio and power range is negligible. Distortion at listening levels (1W) is unmeasurable.


        The FA500 has two 500 watt Ncore amplifiers which can also be bridged to form one powerful 1000 watt amplifier. The third channel is 100 watt Ncore tweeter channel. A variety of input options ensure compatibility with most source equipment. Hypex provides their HFD (Hypex Filter Design) software to design and configure filters for the FusionAmp. You can easily add functionality to the FusionAmp with the Fusion Remote Kit for remote controllability. Due to thermal regulation these FusionAmp's are not airtight.


        To protect your valuable drivers, the DSP does not contain a filter out of the box. A filter needs to be configured and uploaded using Hypex Filter design (HFD) software before the FusionAmp will produce an output signal. You can download the HFD software at Hypex.

        Einfach zu bedienen, tut was es soll. Der Lüfter geht sehr spät an und ist nicht hörbar. Klanglich absolute Oberklasse. Keinerlei Standby oder Aus- und Einschaltgeräusche. Ein Rauschen ist im Vergleich zu anderen DSPs auch nicht zu hören. Mehr Plateamp geht nicht!
