Helix H400X 4 channel amplifier
H 400X
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. This is the recipe for success for the particularly flat precision amplifiers, which, thanks to their sophisticated processor control, don’t get their feathers ruffled in any situation. Improved again and again over the years, these powerhouses with the characteristic, transparent enclosure covers have reached a sound level that is unrivalled, not only in the value-for-money category.
- Extremly stable amplifiers in an extraordinary shallow heatsink
- Fastest drivers for lowest possible THD
- Processor-controlled technology for optimized operation
- Fully active crossover with highpass, lowpass and bandpass filter
- “Input mode” switch for flexible input signal routing
- RMI (Realmixed Input) for generating an optimised mono-summing signal from the left and right channels
- Smart protection circuits against overheating, over- and undervoltage, 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
