Schmallenberg, August 2019 – The BRAX DSP is a prime example of years of ambitious development work and craftsmanship. With this digital signal processor, Audiotec Fischer has set another milestone that completely redefined the benchmark since its market launch in late 2018. Now, with the win of the EISA Award as the best product in the category "IN-CAR SOUND PROCESSOR 2019-2020", the exceptional position of the BRAX DSP is once again manifested and valued accordingly. The most elaborate and complex device ever built by Audiotec Fischer represents with unparalleled technical effort and finest materials not only the sonic pinnacle but offers as well, thanks to its modular design, a maximum of flexibility and future security.
The EISA members justified the awarding as follows:
DSP for optimising in-car sound is nothing new, but Brax takes it to the next level with no fewer than 12 channels of processing across modular input and output cards. This design allows complete tailoring to your in-car audio configuration, with digital or analogue inputs, or a mix of both, using three Analog Devices Sigma 350 64-bit processors, capable of an incredible 3.6 billion calculations per second. ADCs and DACs are by Asahi Kasei, there´s extensive power supply regulation, while the modular approach extends to an add-on card for direct Bluetooth and hi-res USB streaming. This is signal processing without limits.
The Audiotec Fischer Team is very proud and sees the new award as a further motivation to create innovative high-end products for ambitious music lovers.
