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.
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.
The UP 7DSP is the most powerful MATCH DSP amplifier and comprises our new ADEP.3 circuitry. It offers seven amplifier channels in total as well as an additional preamp output, which allows – in combination with its integrated 8-channel DSP – to perfectly drive individual and complex speaker configurations. Two of the output channels deliver 160 Watts RMS into 2 Ohms – plenty enough for fuelling even large subwoofers.
But brute force is nothing without “smart control” – that’s why the UP 7DSP incorporates a stunning powerful 64 Bit DSP of the latest generation, which enables to realize all-new revolutionary and proprietary sound features like the “Augmented Bass Processing”, the “StageXpander” or the “RealCenter” function. Take us by our word – you will experience a truly breathtaking sound performance.
But that’s not enough – simply enjoy music from your smartphone in unprecedented quality. The UP 7DSP comes up with a MATCH Extension Card slot (MEC) for additional input and output interfaces like e.g. our Bluetooth® Audio Streaming module or a High Resolution Audio USB sound card.
Thanks to our professional and user-friendly DSP PC-Tool software V4 the configuration and set-up of the UP 7DSP is pretty straightforward and intuitive.
The “M package” for your BMW HiFi sound system (option 676) – The MATCH UP 7BMW is a revolutionary sound upgrade for those who desire significantly more power and dynamics, but also care about seamless integration into the vehicle.
The installation is done in the blink of an eye at the mounting position of the original amplifier thanks to the included Plug & Play connection cable and a custom-fit mounting plate. Nevertheless, the UP 7BMW amplifier is so flexible that it can easily be used for universal applications in BMW vehicles.
Besides Audiotec Fischer’s proprietary Class HD technology and the cutting-edge 64 Bit DSP with tremendous processing power, new and high innovative DSP features such as “Augmented Bass Processing”, the “StageXpander” and the “RealCenter” function guarantee top-class listening pleasure.
Of course, the UP 7BMW also offers a MATCH Extension Card slot (MEC slot) for additional input and output modules such as a Bluetooth® Audio Streaming module or a High Resolution audio USB sound card.
Thanks to the professional and user-friendly DSP PC-Tool software V4 the configuration of the UP 7BMW becomes straigthforward and intuitive.
