BRAX DSP , 12 Channel High End DSP

  • The BRAX DSP
    The impossible takes a little longer – from the very first idea in 2011 until the sales start at the end of 2018 the all-new BRAX DSP went through the longest and most intensive development process in the history of Audiotec Fischer. Desperately awaited from many customers all over the world we proudly present the most advanced digital signal processor which is – without any doubt – redefining both sound quality and functionality. It is not only the first DSP on the market which deserves to bear the famous BRAX logo but it also elevates the performance standard to an unrivalled level.
    Audiotec Fischer 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. The signal conversion is handled by the best sounding A/D and D/A converters from Asahi Kasei with specifications beyond imagination.

    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 new high-performance 32 Bit CoProcessor (ACO) supervises every operation and assures fastest communication with the DSP PC-Tool software and the optional remote control DIRECTOR.
