The BRAX DSP

The impossible sometimes takes a little more time - from the initial idea in 2011 to the start of sales at the end of 2018, the completely newly developed BRAX DSP went through the longest and most complex development process that has ever existed in the history of Audiotec Fischer. Eagerly awaited by customers around the world, we proudly present the most advanced digital signal processor that will undoubtedly set new standards in terms of sound quality and functionality.
Not only is it the first signal processor on the market to rightly bear the BRAX logo, but it also raises the standard to a previously unique level. Audiotec Fischer has spared no effort to take every single detail of this technological masterpiece to the extreme.

The heart of this signal processor consists of no less than three (3!) of the most powerful 64-bit audio DSPs from Analog Devices' Sigma350 series. The concentrated computing power of 3.6 billion MAC operations per second makes it possible to operate the entire signal path with the native sampling frequency of 192 kHz and thus expand the audio frequency response up to 80 kHz. The signal conversion itself is carried out by Asahi Kasei's AD and DA converters, which are currently the best in terms of sound, with measured values ​​beyond the previous imagination.

With regard to the power supply within the device, an almost epic effort was made as the indispensable basis for perfect sound quality. An armada of no fewer than 55 voltage regulators smooths and stabilizes all supply voltages of each individual assembly separately. A new, enormously powerful 32-bit CoProcessor (ACO) constantly measures all voltage values ​​and temperatures and guarantees optimally fast communication with the DSP PC-Tool software and the optional DIRECTOR remote control.

But in addition to all its technical advantages, the BRAX DSP also marks the beginning of a completely new era in terms of connectivity. Its unique, modular concept allows both the inputs and the outputs to be configured as analog or digital plug-in modules. There are also two slots for expansion cards (BEC – BRAX Extension Card) and a link module for future system expansion. So it's hard to imagine that the BRAX DSP, with its unprecedented flexibility, isn't able to implement every conceivable system configuration - whether today or in the future.

The overall "work of art" is completed by a mechanical concept, which gives the impression of immortality at first glance. Here, too, the enormous effort - starting with the massive heat sink in the typically linear BRAX design through to the cinch sockets milled from solid material - can be seen down to the smallest detail.
