Mosconi Atomo 1

The Mosconi ATOMO 1 is an extremely compact and powerful 1-channel Class-D amplifier that, despite its minimal dimensions, delivers an impressive output power of up to 350 watts RMS at 2 ohms. Thanks to its efficient digital technology, this mono amplifier is ideal for driving subwoofers and high-power speaker systems in spaces with limited installation room.

With its flexible high-level and low-level inputs, the ATOMO 1 can be integrated into both existing factory sound systems and custom-built car audio systems. The automatic power-on function via the high-level signal, the switchable 80-Hz low-pass filter, and start-stop compatibility enable versatile use.

The high-quality, black anodized aluminum housing measures just 86 x 65 x 34 mm. As a result, the Mosconi ATOMO 1 offers an outstanding combination of performance, efficiency, and a space-saving design.
