HELIX C ONE Amplifier Overview The HELIX C ONE is a premium 1-channel amplifier designed to deliver exceptional power and sound quality. Its ultra-low-noise Class A driver stage, coupled with 32 hand-selected MOSFET power transistors, ensures precise control over speakers, achieving a remarkable damping factor of 1,000 at 4 ohms. This makes it an ideal choice for driving powerful subwoofers and high-resolution audio systems. Key Features High Power Output: Delivers up to 1,100W RMS at 1Ω, suitable for demanding subwoofers. High-Resolution Audio: Frequency response up to 80 kHz ensures accurate reproduction of high-resolution audio content. Class A Driver Stage: Provides ultra-low noise and distortion for pristine sound quality. Advanced Power Supply: Regulated DC/DC switching with Start-Stop capability down to 6V ensures stable operation even during engine cranking. TwinPower Link: Allows bridging of two amplifiers for increased power output. Optional Digital Input Module: The HDM 1 module adds an optical SPDIF input with 32-bit Burr-Brown D/A converters for digital audio sources. Robust Build Quality: Features 24-carat gold-plated terminals and a quad-layer PCB with 70μ copper traces for minimal signal loss. Output power RMS / max.
