【Matrix MX4 PRO｜Digital Input Compatible, 4ch High-End Power Amplifier】

If you want to build a system with a focus on the amount of musical information and a sense of depth and dimensionality, the power amplifier that ultimately amplifies the audio signal is just as important as the speakers and DSP.

Matrix MX4 PRO is a four-channel power amplifier developed over seven years as a German-made, hand-built amplifier. It supports digital input, and by connecting to the digital output of a BRAX DSP, you can use the DiSAC (Digital Signal Analog Controlled) function. The design aims to transmit digital signals with full-bit resolution, delivering the information contained in the source to the amplifier while minimizing loss as much as possible.

The digital input supports sampling rates of 28kHz–192kHz via coaxial SPDIF and 28kHz–96kHz via optical SPDIF. It is well-suited for those who want to build a system centered around the DSP and for those who want to clearly hear even the subtle nuances in the sound.

The power amplifier section inherits the circuit configuration of the MX4 and employs selected 4-parallel Hi-END MOS-FETs. It operates in AB class, delivering an output of 300W × 4ch. Specifications such as a damping factor of 1400 or higher, distortion of 0.0005% or less, and an S/N ratio of 116dB or higher provide a solid foundation for reproducing music powerfully and accurately without smearing it.

However, the final result is not determined by the amplifier’s performance alone. Depending on the combination with the speakers, power and signal routing, installation method, and DSP adjustments, the overall impression of the finished sound can differ even with the same amplifier. If it were me, I wouldn’t choose the Matrix MX4 PRO on its own—I would first review your current system and listening style, and also consider which parts to entrust to this amplifier.

If you feel, “I want a bit more headroom in my current sound,” “I want a system that won’t fall apart even when I turn the volume up,” or “I want to make full use of the DSP’s performance,” please consult us. We will sort out together a configuration that lets you enjoy music comfortably after installation, tailored to your vehicle and usage environment.
