    Product details

    Hypex FA123 2x125 + 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 FA123 has two 125 watt Ncore amplifiers which can also be bridged to form one powerful 250 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 here.

    Ok, I expected something good and an improvement, but the way these have improved the sound from my speakers surpasses all expectations. The low distortion characteristic and clean/transparet sound is simply phenomenal. Too bad you can't get this product in a non-plate version, because that is how I am forced to use these, but there is a way aroin that too. Communication between pc and plate and plates among themselves was a bit quicky on some occasions, but only when laptop conncected.
