Thanks to its flat design and sophisticated processor control, the Helix H 400x 4 channel amplifier improves your audio experience, reaching high sound level.

The best of both worlds – extremely fast MOSFET driver circuits in Class A operation combined with enormously load-stable, power-potent “afterburners” in bipolar technology. These powerhouses with the distinctive and clear enclosure covers have consistently improved over the years to achieve a sound quality that is unrivalled.

Main Features:

 

  • Extremely stable amplifiers in an extraordinary shallow heatsink
  • Unique Bipolar output transistor technology for unparalleled natural and warm sound experience
  • Fastest drivers for lowest possible THD
  • Processor-controlled technology for optimised operation
  • Fully active crossover with high pass, lowpass and bandpass filter
  • “Input mode” switch for flexible input signal routing
  • RMI (Real mixed Input) for generating an optimised mono-summing signal from
    the left and right channels
  • Smart protection circuits against overheating, over- and under voltage, speaker short circuiting, low impedance and faulty connection
  • 24 carat gold-plated solid connection terminals suitable for 25 mm² / gauge 4
  • Completely made in Germany by using only selected components
