4 Channel

  • Audison AP4 D

    The AP4 D amplifier was designed as an extension for the AP 4.9 bit and AP 5.9 bit amplifiers, offering 4 additional 70 W amplified channels.

  • Audison AP4.9 bit

    AP4.9 bit amplifier is ideal to realize a powerful two way front full active. The built-in processor, that this amplifier shares with the AP8.9 bit, provides the ability to assign the pre-outs to the AP1 D amplifier, creating a very powerful system in a small space thanks to the “rack mounting” system.

  • Helix C FOUR

    Audiophile sound quality combined with impressive output power

    The C FOUR is a high-end 4-channel amplifier that has been designed down to the last detail for ultimate sound quality. Audiotec Fischer’s proprietary 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. 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.
    In combination with the optionally available digital input module HDM 2, the C FOUR demonstrates the perfect transition to the digital era. The HDM 2 accepts digital audio signals up to 96 kHz sampling rate via its two optical inputs followed by cutting-edge BurrBrown D/A converters with 32 Bit resolution that transform the signals back to the analog domain. Therefore the C FOUR is absolutely future-proof and perfectly prepared for the combination with our digital signal processors.

  • Helix D FOUR

    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 sound reproduction – the active crossover with highpass filter, lowpass filter, bandpass and bass boost are equally as self-evident as the intelligent highlevel input that incorporates Audiotec Fischer´s proprietary ADEP circuit. It is even possible to add an optional volume remote control for the amp channels C and D which is very useful if those outputs are firing a subwoofer.

    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. That is sound-tuning at its best!

  • Helix G FOUR

    The new G amplifiers are more than just impressive power packs. They unite innovative technology, extensive functionality and best sound with a very attractive price to performance ratio.

    If we do not talk about their more obvious features, such as fully active crossovers with highpass, lowpass, bandpass, bass boost and input mode switch for flexible input signal routing and smart high level input with ADEP circuits, we can still talk about how the G series also provides Start-Stop capability which is an exceptional feature in this price range. Wait, that’s not all… a remote control for adjusting the subwoofer level is included as part of the deal.

    With such an extensive list of features in this piece of equipment, it is really not hard to realize a sound system in your car that has a great sound and lots of power for when you need it most.

    Furthermore, the G amplifiers have the compact and straight HELIX design that has become synonymous with HELIX. In addition, for those who love a good light show, the logo has been illuminated for your viewing pleasure.

  • Helix H 400X

    The best of both worlds – extremely fast MOSFET driver circuits in Class A operation combined with enormously load-stable, power-potent “afterburners” in bipolar technology. This is the recipe for success for the particularly flat amplifiers, which, thanks to their sophisticated processor control, don’t get their feathers ruffled in any situation. Improved repeatedly over the years, these powerhouses with the characteristic and transparent enclosure covers have reached a sound level that is unrivalled, and not just in the value-for-money category.

  • 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.
