HELIX AMPLIFY 206 DSP

HELIX AMPLIFY - Powerful. Clear. Consistent.
With AMPLIFY, HELIX redefines the standard for modern amplifier design: through the contemporary interpretation of classic concepts. Instead of "one-fits-all" solutions, AMPLIFY focuses on specialized models that are precisely tailored to different areas of application. This stringent philosophy guarantees: Each model delivers maximum performance for its intended use - while concentrating on the essentials.

The 2-series marks the entry into the AMPLIFY platform - and at the same time forms its technical and sonic core. These compact Class D amplifiers combine power, a fully bridgeable multi-channel architecture and outstanding efficiency with practical integration capability. Brilliant and precise highs, controlled mids and tight, powerful bass - the 2-series brings all facets of natural and powerful sound to every vehicle with sound quality and performance values far above the expectations of its class. Whether as a DIRECT, X-OVER or DSP variant (from summer 2025): From flexible 6-channel configurations for full-range applications to the powerful 1-channel subwoofer powerhouse, everything is on offer.

TuneEQ
TuneEQis an extremely flexible and particularly easy-to-use function for automated frequency response correction. A single measurement per audio channel or channel pair with a suitable measurement microphone (such as our AMI Tuning Kit) is all it takes for TuneEQ to adjust the equalizers independently and precisely to the desired reference curve. TuneEQ uses the entire range of functions of the parametric equalizer, including the mid frequency, the Q factor and the gain. And because the highly complex computing operations required for this run in the background, you also save a lot of time when tuning the sound with TuneEQ.

RealCenter
The "RealCenter" function is a proprietary algorithm from Audiotec Fischer that emphasizes the monaural information of the left and right front channels to create a unique center signal. In contrast to conventional methods, where only the channels are summed up, the center signal is also dynamically controlled by the stereophonic information content of the left and right channels. This means that the center channel does not reproduce a signal if only the left or only the right channel delivers an audio signal. With conventional algorithms, the center channel would only be 6 dB quieter in this case. Audiotec Fischer's "RealCenter" therefore enables a unique, wide-ranging soundstage - and this is optimal for both driver and front passenger! The disadvantages of a conventional center channel, such as an intrusive, narrow spatial sound presentation, are finally a thing of the past.

Augmented Bass Processing
Audiotec Fischer's proprietary "Augmented Bass Processing", consisting of two revolutionary sound features: "Dynamic Bass Enhancement" and "SubXpander". These have been specially developed to dramatically improve the bass response of subwoofers.

"Dynamic Bass Enhancement" ingeniously combines maximum low bass foundation and high maximum sound pressure - regardless of the type of music you are listening to or the sound settings on the radio. Depending on the input signal, "Dynamic Bass Enhancement" boosts the lower frequency range on the one hand and varies the cut-off frequency of the subsonic filter on the other. The result is a much more powerful, deeper bass reproduction at low and medium volumes without running the risk of mechanically or electrically overloading the subwoofer at high volumes. The bass performance that is suddenly possible is simply fascinating.

If you want the bass range to be a little deeper and "blacker", you can also activate the "SubXpander". Here, subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.
