Audison Prima AP F8.9 bit
8 CH AMPLIFIER WITH 9 CH DSP
The new AP F8.9 bit is the ideal for the most demanding integration projects, where high power is required along with the flexibility of the nine-channel DSP. The word “Forza”, meaning “Power” in Italian, well describes the 8 x 85 W RMS and 4 x 260 in bridge mode (RMS @ 4Ω), with an optimal power to size ratio.
The integrated processor is equipped with a dedicated software and 7 pre-configured presets for a Plug & Sound experience. Thanks to the built-in Audison USS technology (Universal Speakers Simulator), AP F8.9 bit can also be correctly connected to head-units with “speaker load detection” function that monitors the presence of a low-impedance load to enable the audio outputs.

Helix M FOUR
If you like to rev up your front and rear speakers, the M FOUR will be exactly the right “tool” to do so. With generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load this amp will heat up your voice coils in no time despite its super-compact dimensions. On the other hand the M FOUR stays totally cool thanks to the highly efficient Class D design topology. 3-channel or 2-channel configurations are possible as well, delivering up to 2 x 200 Watts RMS of clean and undistorted output power.
Needless to say that the M FOUR is equipped with a bunch of intelligent attributes like “start-stop capability” and our proprietary “ADEP” highlevel input so that it easily deals with all installation challenges of modern cars. Finally the extensive audio features will offer a sound quality at its best.

Helix P SIX DSP MK2
$7,500.00The HELIX P SIX DSP MK2 6-channel amplifier is not built to solely deliver loads of clean power; it also incorporates a cutting-edge 8-channel DSP with outstanding processing power. This amalgamation sets a completely new standard with its “Ultra HD Class D” amplifier technology.
Thanks to its 96 kHz sampling rate and an extended audio bandwidth of more than 40 kHz, this technological feat of precision engineering raises the bar in terms of sound quality.
If we put all that aside for a moment, versatility was another major milestone to be reached during the development process. Therefore, we are happy to introduce HEC. The HELIX Extension Card (HEC) slot allows you to extend the devices possibilities well beyond the commonplace RCA jacks. Interfaces like a Bluetooth® Audio Streaming module or a High Resolution Audio USB soundcard have been crafted to give you more options than ever.
Two fully-processed RCA outputs provide connectivity for daisy-chaining more amplifiers without a need for a second DSP.
The configuration of the internal 64 Bit DSP could hardly be easier thanks to the professional and user-friendly DSP PC-Tool software that offers almost unlimited sound tuning features.
Despite this impressive feat of engineering, the P SIX DSP MK2 has not shed its HELIX design heritage; it still has the clean design while remaining very compact for ease of installation.

Helix D ONE
The new entry into the HELIX world! The amplifiers of the D series are solely modest with respect to pricing. Everything else is thoroughly pure HELIX quality without any compromises. Loads of power, excellent measurement data and a whole bunch of features ensure a pristine and crispy sound experience!
Absolutely nothing has been missed for powerful bass reproduction – the active crossover with subsonic filter, the lowpass filter, phase control and bass boost are equally as self-evident as the intelligent highlevel input that incorporates Audiotec Fischer´s proprietary ADEP circuit. Not to mention the cable remote control for volume that is included in delivery.
Thanks to its 1-Ohm stability the D ONE is every else but choosy when selecting an appropriate subwoofer. If you still think that the power output isn’t sufficient, then simply combine two devices to one single powerhouse – the master/slave option makes it possible.The elegant design not only states right from the beginning the amp’s heritage but also allows an easy integration into your car thanks to its compact dimensions. Get your car “bass-tuned” and simply have fun!
