The AP1 D amplifier was designed to drive a subwoofer and is the ideal extension of the AP8.9 bit and AP4.9 bit. At 2 Ohms it is stable and can supply 540 W power with extremely compact dimensions. With the APTK 3 (Audison Prima Tower Kit 3) stacking system it’s possible to stack the AP1 D and save space without any problem of overheating.

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.
As small as a cigarette packet but a giant in performance and function: the brand-new M 5DSP amplifier provides huge power and cutting edge technology in a remarkably small housing.
Five channels, a powerful 7-channel “fixed point” Audio DSP with 56 Bit resolution and proprietary Class GD technology predestine the amplifier for ultimate car audio performance. Its minimal dimensions as well as its high efficiency and low heat dissipation allow unprecedented space saving and hidden installation concepts, that were not previously possible.
The M 5DSP is featuring two power modes: it can be driven optionally in “HighPower” mode for maximum performance or in “MidPower” mode with reduced output power and lower power consumption for Plug & Play applications.
A subwoofer output, a remote output and a freely configurable 2-channel PreOut for hooking up additional amplifiers offers further connectivity.
Thanks to Audiotec Fischer’s DSP PC-Tool software the integrated DSP can easily configured to individual requirements. The scope of delivery includes a connection cable and an adapter cable to dock a MATCH Plug & Play or a conventional subwoofer.
The sound power house – extremely powerful and stunning sound quality
The C ONE is a high-end 1-channel amplifier that is able to drive even powerful subwoofers to the max. The 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.
Additionally the intelligent regulation of the power supply assures stable conditions for the output stages and therefore phenomenal output power that is almost independent of the cars battery voltage. And for even more output power, two C ONE amplifiers can be combined to one single powerhouse – thanks to the TwinPower Link.
Despite its impressive output power, the C ONE is by no means a pure subwoofer amplifier. Thanks to an extended frequency response up to 80 kHz and an architecture that has been designed down to the last detail for ultimate sound quality, the C ONE is also a perfect buddy for heavy-duty mid-woofers in audiophile system concepts.
In combination with the optionally available digital input module HDM 1, the C ONE demonstrates the perfect transition to the digital era. The HDM 1 accepts digital audio signals up to 96 kHz sampling rate via its optical input followed by cutting-edge BurrBrown D/A converters with 32 Bit resolution that transform the signals back to the analog domain. Therefore the C ONE is absolutely future-proof and perfectly prepared for the combination with our digital signal processors.
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!
