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.

Match M 2FX
Tiny amplifier with big ambitions – the M 2FX combines smallest dimensions with huge power and highest versatility.
Equipped with an active crossover with high- or lowpass, stereo line input and highlevel inputs with ADEP circuit as well as further top-notch features this ultra compact two channel amplifier perfectly acts as a stand-alone amplifier for demanding speaker systems or as power source for subwoofer applications. Due to its load stability the M 2FX is almost predestined for driving subwoofers with 2 x 2 Ohms impedance.
The proprietary Class GD technology combines excellent sound quality with extraordinary high efficiency. Thanks to its minimal dimensions and low heat dissipation unprecedented space saving and hidden installation concepts can be realized that were previously impossible.
In combination with the five channel amplifier M 5DSP from the MATCH portfolio the M 2FX is literally a “perfect MATCH”.

Match M 5DSP MK2
Huge power in a tiny format
Hardly bigger than a smartphone but a giant in performance with an incredible output power of 400/ 800 Watts RMS/ max. and five amplifier channels.
These amazing figures in such a tiny space result from Audiotec Fischers proprietary Class HD-technology, which guarantees an unrivaled efficiency and therefore minimum heat dissipation. Even better – this offers unimagined possibilites when choosing the mounting location.ACO – Advanced 32 Bit platform
The M 5DSP MK2 is the first MATCH amplifier equipped with our new, extraordinary powerful 32 Bit ACO platform. This provides higher speed during the communication with our DSP PC-Tool software, but also when switching between the 10 internal memory locations for sound setups. In addition, the ACO offers an integrated, channel-separated Input EQ and Input Signal Analyzer (ISA), e.g. for compensating any kind of equalizing in the factory radio.Latest DSP technology
The extremely powerful 64 Bit audio DSP with its seven channels offers in combination with the CoProcessor ACO amazing DSP sound features, like the “Augmented Bass Processing”, the “StageXpander” and the “RealCenter” function and thus completely new possibilities in sound tuning.Power on demand
That’s unique – the M 5DSP MK2 features two power modes, allowing it to run either in “HighPower” mode for maximum performance or in “MidPower” mode with reduced output power and lower power consumption for Plug & Play applications without a separate power supply.Intuitive DSP PC-Tool
Such a bunch of technology must remain operable – our professional and user-friendly DSP- PC Tool software V4 impressively demonstrates that a huge feature set and an easy configuration can be perfectly harmonized. -
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.
