HELIX C ONE 1

The sound powerhouse ? extremely powerful and stunning sound quality

The C ONE is a high-end 1-channel amplifier that is able to drive even powerful subwoofers to the max. The ultra-low-noise and ultra low-distortion Class A driver stage feeds a total of 32 hand-selected MOSFET power transistors, resulting in an incredible damping factor of 1,000 for relentless control of every loudspeaker.

Additionally, the intelligent regulation of the power supply assures stable conditions for the output stages and therefore phenomenal output power that is almost independent of the cars battery voltage. And for even more output power, two C ONE amplifier can be combined to one single powerhouse ? thanks to the TwinPower Link.

Despite its impressive output power, the C ONE is by no means a pure subwoofer amplifier. Thanks to an extended frequency response up to 80 kHz and architecture that has been designed down to the last detail for ultimate sound quality, the C ONE is also a perfect buddy for heavy-duty mid-woofers in audiophile system concepts.

In combination with the optionally available digital input module HDM 1, the C ONE demonstrates the perfect transition to the digital era. The HDM 1 accepts digital audio signals up to 96 kHz sampling rate via its optical input followed by cutting-edge BurrBrown D/A converters with 32 Bit resolution that transform the signals back to the analogue domain. Therefore the C ONE is absolutely future-proof and perfectly prepared for the combination with our digital signal processors.
