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.
These reference speakers in our C-series raise the bar to a new level of fantastic sound quality. The legendary sisal woofer cones are equipped with an additional structural damping layer made of an elastomer, which again improves the acoustic properties of the driver. The tweeter enclosure also underwent a complete overhaul. Anyone who wants to operate these loudspeakers as fully active speakers (e.g. using our new digital signal processors) can put together the system of their choice by combining the individual components.
Like the loudspeaker systems, the frequency crossovers of the components systems have also been optimized even further. Made up of the finest components, they offer, in addition to the adjustment of the tweeter level, the option of connecting a second woofer for each channel without any change in the crossover frequencies. The so-called “double woofer mode” provides for additional pressure in the frequency range where the bass will really kick
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.
Compact in size but huge in sound. The new enclosure subs of the K series don’t show any mercy when their hefty beats make your car shake, rattle and roll.
Lots of technical finesse was necessary to fulfil the demands of SPL junkies and audiophile music lovers at the same time. Rock-solid cones made from hand-scooped paper in combination with heavy-duty voice coils easily transform the power of your amplifier into loads of sound pressure without neglecting neither acoustical details nor sonic precision.
Fortunately the K subwoofers are no wasters of precious trunk space at all thanks to their compact cabinet dimensions.
By the way – the double voice-coil design offers more flexibility when selecting an appropriate power amp. No matter if 1 x 4 Ohms, 2 x 2 Ohms or 1 x 1 Ohm – these “deep bass warrantors” make any configuration easily possible.
The 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.
Bass is in the smallest hut – If mounting space in the vehicle is scarce and existing car hifi systems badly need the “extra kick” in the low frequency range without great effort, the new HELIX active subwoofers U 10A and U 8A are the right choice. Driven by powerful, integrated Class AB amplifiers with 180 W RMS, the heavy-duty drivers with their rock-solid aluminum cones and heat-resistant voice coils easily transform the amplifier power into punchy bass. Thanks to comprehensive setting options like the adjustable, high-slope lowpass filter and particularly sensitive phase control, the low frequency reproduction can be perfectly adapted to the acoustic conditions inside the vehicle. Equipped with a 2-channel highlevel input with automatic turn on function as well as a 2-channel lowlevel RCA input a seamless integration is guaranteed. And thanks to the especially shallow cabinet design the installation will be a no-brainer, especially if space is extremely limited – these small “bass boosters” may even fit under the seats, for example.
The HELIX V EIGHT DSP 8-channel amplifier with integrated 10-channel signal processor opens up new horizons for car audio enthusiasts.Its unique “Pure Class GD” concept and cutting-edge “fixed point” Audio DSP with 64 Bit resolution ensures extraordinary sound quality and loads of power.Furthermore, a huge feature set provides the ideal set of pre-requisites for more complex system concepts – especially if fully active configurations are going to be built on a single and compact amplifier.Eight speaker outputs with up to 120 Watts RMS @ 2 Ohms, two processed RCA outputs for the connection of additional amplifiers, six RCA and six highlevel inputs with up to 20 V RMS input sensitivity and an optical SPDIF input make this amplifier absolutely unique in its class. The HELIX Extension Card slot (HEC) allows adding even more interfaces, like the Bluetooth® Audio Streaming module or a High Resolution Audio USB soundcard.
Thanks to Audiotec Fischer’s DSP PC-Tool, the integrated DSP can be easily configured to ones individual requirements. Despite the gigantic feature content, the V EIGHT DSP presents itself in the classic HELIX design language, a clean design with very compact dimensions allows for a quick and easy integration.
