The HELIX C FOUR & C ONE – Two top-notch Class AB amplifiers, with a recognizable relation to BRAX. Both amplifiers use an ultra low-noise and low-distortion driver stage feeding a total of 32 hand-selected MOSFET power transistors that provide an exceptional sound quality. The intelligent regulation of the power supply assures stable conditions for the output stages and therefore phenomenal output power independent of the cars battery voltage. Additionally, both can be upgraded to receive digital signals via the optional SPDIF input module HDM, making the amps ideally suited for the combination with our digital signal processors.
