Brax Amplifier MX4 Pro

BRAX MX4 PRO – Redefining Car Audio Amplification

Is it possible to make the world’s best car audio amplifier even better? The BRAX MX4 PRO answers with a resounding yes. Developed by Audiotec Fischer’s expert engineers, this masterpiece pushes the boundaries of both acoustic and technical performance.

Every detail of the MX4 PRO has been optimized – from hand-selected MOSFET power transistors to an advanced quad-layer PCB design – ensuring unrivalled sound purity and power delivery. With its 4 x 300W RMS stable at 4, 2, and even 1 Ohm, the MX4 PRO delivers flawless control, dynamics, and precision.

The amplifier also introduces DiSAC (Digital Signal Analog Controlled) volume control in combination with the BRAX DSP, ensuring lossless volume adjustment without compromising signal resolution. Its robust power supply with encapsulated toroidal transformers, custom capacitors, and superior heat management guarantees unmatched stability and efficiency.

Each MX4 PRO is custom-built in Germany, engraved with its unique serial number, and supplied with a certificate – making it not just an amplifier, but a collector’s piece of true high-end car audio engineering.
