Musway M12

The Musway M12 is a powerful 12-channel Class D amplifier with an integrated 16-channel digital sound processor (DSP), enabling comprehensive sound optimization and flexible integration into modern in-car audio systems. With up to 12 x 120 watts RMS at 2 ohms, the M12 delivers ample power for complex speaker configurations and demanding car audio applications.

Thanks to its extensive connectivity options—including 12 high-level inputs, 6 RCA inputs, an additional AUX input, and an optical digital input—the amplifier can be integrated into both factory-installed and aftermarket sound systems. The built-in EPS® Error Protection System prevents error messages from the vehicle diagnostic system when using the high-level inputs.

The powerful 64-bit DSP running at 295 MHz enables precise adjustment of all audio channels. Using the Musway DSP software, you can individually adjust crossovers, equalizers, time corrections, and other sound parameters. Additionally, four freely configurable RCA outputs are available for integrating external amplifiers or subwoofer power amplifiers into the DSP system.

With optional Bluetooth dongles, wireless audio streaming and control via a smartphone app are also possible. Its compact design, automatic power-on function, and start-stop compatibility make the Musway M12 a versatile solution for high-quality car audio systems.
