HELIX C ONE – Mono Class AB Audiophile Car Amplifier | 1-Channel
The HELIX C ONE represents the pinnacle of amplifier engineering — where audiophile sound quality and immense power meet in perfect harmony. Built in Germany by Audiotec Fischer, the C ONE is designed to drive even the most demanding subwoofers and mid-woofers with absolute control, precision, and musical depth.
Unmatched Amplifier Performance
Delivering up to 1,100 W RMS @ 1Ω, the C ONE’s Class AB design ensures natural, distortion-free sound reproduction across an extended frequency response up to 80 kHz — ideal for both subwoofers and high-fidelity midrange applications.
Advanced Engineering Excellence
Equipped with a Class A driver stage and 32 hand-selected MOSFET transistors, this amplifier achieves an astonishing damping factor of 1000, guaranteeing tight, accurate bass and flawless speaker control. The regulated DC/DC power supply maintains consistent output power regardless of vehicle voltage fluctuations — even during engine start (Start-Stop capable down to 6V).
Future-Proof Connectivity
Designed for the digital era, the C ONE supports the optional HELIX HDM 1 digital input module, featuring BurrBrown 32-bit D/A converters for pristine high-resolution playback. This ensures perfect integration with HELIX or MATCH DSP processors and advanced car audio systems.
Precision & Protection
Microprocessor-based system monitoring, thermal control, and gold-plated terminals ensure reliability, stability, and long-term performance. Flexible input mode switching and advanced crossover controls allow complete customisation of your sound stage.
Audiophile Sound in Every Detail
Combining German craftsmanship with cutting-edge Class AB technology, the HELIX C ONE delivers unparalleled fidelity, breathtaking dynamics, and musical transparency — a true reference amplifier for high-end automotive audio systems.
