In its diversity, music directly touches the heart of the listener. You can almost hear and feel the passion when the sound is reproduced as the performer intended. 
For this reason, Audiotec Fischer develops the HELIX audio products with the same dedication and precision as their reference devices from BRAX. As with the quality of a musical instrument, high-quality audio components have a significant influence on the naturalness of the timbre. We believe in having found the perfect DNA of sound in HELIX, resulting in a realistic and powerful sound inside your car.

Sound quality at the highest level by music lovers for music lovers. More high-end sound inside a vehicle is hardly possible.


Like no other brand, HELIX stands for the development and manufacturing of the most sophisticated car hi-fi components with its decades of experience. The brand's success is no coincidence, but rather the result of meticulous research and numerous, proprietary core technologies.

Each of the HELIX products is designed and developed in-house by Audiotec Fischer down to the last detail. The result is a smart product range with an ideal solution for every application. Always with the aim of satisfying our basic need for rhythm and music.


 The power supply has a significant influence on the sound quality. Only with a stable power source in all modules is it possible to guarantee full dynamics and purity of the reproduction.

Audiotec Fischer's proprietary power supply technologies combine maximum efficiency with minimum space requirements. In addition unconditional stability regardless of the on-board voltage is guaranteed – ideal for use in vehicles with start-stop feature.


Anyone who speaks of high-end hifi in the digital domain also automatically considers hi-res audio formats such as Tidal, Deezer or Qobus.

With HELIX we offer a complete signal chain with HiRes-capable DSPs and amplifiers, which enables loss-free audio playback in the car.

More high-end sound inside a vehicle is hardly possible!
