POWER HELIX H 400X. 4 Channel. Class AB. GERMANY.

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 amplifiers, which, thanks to their sophisticated processor control, don’t get their feathers ruffled in any situation. Improved repeatedly over the years, these powerhouses with the characteristic and transparent enclosure covers have reached a sound level that is unrivalled, and not just in the value-for-money category.
