M4nano

4-CHANNEL CLASS D AMPLIFIER WITH 8-CHANNEL DSP

With the new M4nano, MUSWAY introduces a DSP amplifier in an ultra-compact format. Measuring just 150 x 95 x 45 mm, it fits almost anywhere in the vehicle and combines four powerful Class-D amplifier channels with a full-featured 8-channel DSP. The M4nano delivers 4 x 55 watts RMS at 4 ohms or 4 x 95 watts RMS at 2 ohms. Alternatively, two channels can be bridged to provide 190 watts RMS at 4 ohms.

Small in size, big on possibilities: The M4nano is suitable for everything from a simple factory system upgrade to a fully active sound system. The 8-channel DSP controls the four internal amplifier channels as well as four additional RCA outputs for external amplifiers, allowing for flexible system expansion at any time. For precise sound tuning, the proven Analog Devices ADAU1452 DSP processor offers extensive functions for equalization, crossovers, time alignment, phase, and routing. Up to six DSP setups can be saved and conveniently configured via PC software or an optional app.

With six high-level inputs (up to 24 volts RMS), EPS circuitry, auto-turn-on, and start-stop compatibility, the M4nano is ideally equipped for integration into modern vehicles. Thanks to the practical 20-pin MX-Connect port, it allows for convenient plug-and-play installation using optional vehicle-specific cable sets. Optional Bluetooth modules are available: the BTS for audio streaming and the BTA-HD for high-quality audio streaming with app control.

In a review by *Car&Hifi* (issue 4/2026), the M4nano demonstrated its true capabilities: in the test lab, it achieved 63 watts at 4 ohms and 116 watts at 2 ohms per channel, thereby exceeding its manufacturer specifications. In terms of sound, it also impressed with low distortion, powerful reproduction, and astonishing power reserves. The result: a top-class rating of 1.2, the "BEST PRODUCT" award, and an "outstanding" price-performance ratio. The verdict: "Super compact, high-quality, and affordable—the perfect entry-level DSP amplifier."

Following the outstanding review by *CAR&HIFI* comes international acclaim: EISA (Expert Imaging and Sound Association) has named the MUSWAY M4nano the "EISA IN-CAR MICRO AMPLIFIER 2026–2027." The international panel of experts particularly praised the combination of its compact size, powerful Class-D performance, flexible 8-channel DSP, and Plug & Play compatibility. With this honor, the M4nano secures one of the industry's most prestigious European awards.
