Astrum SM030 · 2.1-channel desktop speakers
Bring a three-piece speaker setup to the desktop with the Astrum SM030. Two satellite speakers join a central subwoofer, with RGB lighting, a front volume knob and a 3.5 mm audio connection for a compatible computer or other source.
Connect with clarity
Use the USB connection for power and the 3.5 mm AUX input for audio. Check that the source has a suitable audio output and that the USB power source meets the supplied unit’s requirements. A headphone adapter may be needed for a device without a 3.5 mm output.
Set the level at the desk
The front knob puts level adjustment on the subwoofer, while the RGB lighting adds colour around the speakers. Allow space for the central unit and both satellites, and check the dimensions below when arranging them around your monitor.
The detailed manufacturer specification rates audio output at 11 W RMS. Its headline also uses an unqualified “20 W”; this is not presented as a 20 W RMS rating. RMS audio output is not a measurement of power drawn from USB or the wall. Check source audio and USB power compatibility before use.
