Is it possible to make the best car audio amplifier worldwide even better? This was really a challenge for our engineers when they started the development of the MX4 PRO. When designing a BRAX product it is essential to reconsider and optimize every single detail again and again, even if it seems to be less significant at first sight. From our understanding this is the one and only approach how to shift the limits – acoustically and technically – further and further. Finally we are absolutely convinced that the MX4 PRO redefines the benchmark for amplifiers once again.

This masterpiece is the perfect symbiosis of state-of-the-art components and ingenious technological improvements without neglecting the heritage and the tradition of the brand that BRAX is famous for.
As the only manufacturer we still take it for granted to manually select power transistors for the production of each BRAX amplifier – and it is no secret that the necessary instruments and tools for this selection procedure are in-house developments. This one-of-a-kind process not only assures lowest possible serial tolerances but as well unrivalled measurement and power data.

A significant proportion for the overall performance is based on the extensive effort that is made for the power supply of all modules inside our amplifiers. Separate and stabilized supply voltages for each two channels warrant perfect conditions for every amplifier stage. The ultra-low ESR electrolytic capacitors (specially made for Audiotec Fischer) are meanwhile as legendary as our encapsulated toroid power transformers that come up with more than 1,800 watts power supply output just like that. A completely revised PCB design with four massive copper layers in total assures maximum current flow – so it is no wonder that the MX4 PRO with its mere 4 x 300 RMS into 4/2/1 Ohms delivers more power to the speaker terminals than ever before.

But that’s not enough – the MX4 PRO is as well a paradigm for bridging the gap between traditional amplifier technology and the digital era.  We have made an unparalleled effort just for the volume control of the digital inputs. As a novelty in the car audio segment the volume adjustment in combination with the BRAX DSP takes place just before the output stages that drive the speakers – needless to say that this happens in the analog domain without sacrificing any signal resolution. The BRAX DSP embeds the volume information in the digital SPDIF data stream which then is decoded inside the MX4 PRO.

This aspect alone proves the striving of our engineers for pure perfection – and please rest assured that this meticulousness is set to continue throughout the entire production process. Each single amplifier is custom-made on demand and its respective serial number is recorded in our data-base. Therefore every BRAX MX4 PRO is a precious unique product that rightly deserves the title “high-end made in Germany”.
