BRAX DSP – CORE Model
Sometimes, the impossible takes a bit longer – and precisely this level of dedication is reflected in the BRAX DSP. With the longest and most intensive development process ever in the history of Audiotec Fischer, the BRAX DSP is the company's most advanced digital signal processor. Being the first DSP to bear the famous BRAX logo, it impresses with its unparalleled sound quality and outstanding functionality, it elevates the performance standard to an unrivalled level while receiving universal recognition around the whole world.
When it comes to BRAX, you can definitely be sure about one thing: We didn't spare any effort to carry every single detail of this technological masterpiece to extremes: The "heart" consists of no less than three (3!) of the most advanced Sigma350 series fixed-point 64 Bit audio DSP's with the incredible processing power of 3.6 billion MAC operations per second. This allows to run the whole system on a native 192 kHz sampling rate, extending the audio frequency range to 80 kHz. Thanks to its modular architecture, the latest and best A/D and D/A converters, like current state-of-the-art converters from Asahi Kasei and ESS Technology, can be integrated at any time.
Enormous care has been taken for the design of the power supply which is the essential foundation for perfect sound quality. A host of fifty-five voltage regulators cleans and stabilizes all the supply voltages for every single stage separately. A high-performance 32 Bit CoProcessor (ACO) supervises every operation and assures fastest communication with the DSP PC-Tool software and the optional remote controls CONDUCTOR and DIRECTOR.
But besides all its technical merits, the BRAX DSP marks the beginning of a new era in terms of connectivity as well. Its unique modular concept allows to configure the inputs and outputs either as analog, digital or a mix of it. Thanks to this unmatched flexibility, the BRAX DSP makes it possible to integrate even the most complex system configurations – neither today nor in the future.
This masterpiece is completed by a mechanical concept which gives the impression of everlastingness at first glance. Again: the enormous expenditure – from the massive heatsink in BRAX typical straight-lined design to the cinch jacks milled from the solid – is discernible down to the most minute detail.

DSP features
TuneEQ
TuneEQ is an extremely flexible and particularly easy-to-use function for automated frequency response correction. A single measurement per audio channel or channel pair with a suitable measurement microphone (e.g. our MTK1) is sufficient for TuneEQ to independently and precisely adjust the equalizers to the desired reference curve. TuneEQ uses the full function set of the parametric equalizer including center frequency, Q-factor and gain adjustment. And since the highly complex arithmetic operations required for this run in the background, you also save a lot of time when optimizing your sound with TuneEQ.
RealCenter
The “RealCenter” feature is an algorithm, developed by Audiotec Fischer, that emphasizes the music information which is present in both the left and right front channel to create an unique center signal. In contrast to common procedures, in which only the channels are summed up, the intensity of the center signal is also dynamically controlled by the stereophonic informational content of the left and right channel.
Sounds complicated but this effect is astonishing: That means if solely the left or right channel delivers an audio signal, the center channel will not reproduce a signal. In the case of common algorithms, the volume level of the center channel is only reduced by 6 dB (= half volume level). Audiotec Fischer’s “RealCenter” allows a unique, broadened sound staging for both driver and co-driver at the same time! Therefore, the disadvantages of a conventional center channel, such as an intrusive, small sound stage, are things of the past.
Augmented Bass Processing
Audiotec Fischer’s proprietary “Augmented Bass Processing”, consisting of the two revolutionary sound features “Dynamic Bass Enhancement” and “SubXpander”, has been especially developed to dramatically improve the bass reproduction of subwoofers.
The “Dynamic Bass Enhancement” ingeniously combines maximum deep bass and highest sound pressure – regardless of the music style or the tone controls in the head unit. Depending on the input signal, the “Dynamic Bass Enhancement” gains the lower frequency range and varies the cut-off frequency of the subsonic filter. The result is a significantly more powerful and deeper bass response at low and medium volume levels without the risk of overloading the subwoofer neither mechanically nor electrically at high volume levels. It is simply fascinating which bass performance is suddenly possible.
If you want an even lower and “darker” bass reproduction, the “SubXpander” can be additionally activated. Therefore, subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.
