HELIX H 400X - 4 Channel 1000 Watts Class A/B Car Amp Amplifer with integrated, active crossover
The best of both worlds - extremely fast driver stages combined with extremely load-stable and stream-filling "afterburners" in bipolar technology. This is the recipe for success of the particularly flat amplifier, which can not be disturbed by a sophisticated processor control. Continuing to improve over the years, the power packs with the characteristic, transparent housing cover have reached a tonal level that is not only unrivaled in this price and performance class.
Features:
- Extremely stable amplifier in a particularly flat design
- Enormously fast driver stages for minimal distortion
- Processor control of all output stage parameters
- Integrated, active crossover with high pass, low pass and bandpass
- "Input Mode" switch for flexible distribution of input signals
- RMI (Realmixed Input) to form an optimized left and right channel sum signal
- Intelligent electronic protection against overheating, overvoltage and undervoltage, short circuit at the loudspeaker output, impedance underrun and faulty connection
- 24-carat gold-plated, massive connection terminals for permanent lossless signal and power transmission
- Power supply terminals for cable cross sections up to 25 mm²
- Made exclusively from selected components in Germany
