M100 Mini Digital Amplifier COAX / OPT USB Player 24B/192K — Infineon MA12070, 68W+68W, DC 9-20V, 5.0 Amp — Home/Car/Marine HiFi

Compact, feature-rich M100 mini digital amplifier designed for versatile home, car, motorcycle and marine audio use. It offers five input options — PC-USB, Udisk, stereo RCA, coaxial and optical — and supports PC-USB (phone OTG) as well as U-disk playback. The built-in USB player handles lossless formats including WMA, WAV, APE and FLAC and supports 24B/192K audio quality. Outputs include speaker terminals for passive speakers, a 3.5mm AUX preamp output and a 3.5mm headphone jack, so you can drive speakers directly or feed another amp, active subwoofer or active speakers to expand into a multichannel setup. The amplifier uses the Infineon MA12070 chip and delivers a maximum of 68W+68W, easily powering most desktop, bookshelf and indoor passive speakers (4-16). Engineered for flexible installation, the M100 works from a wide DC 9-20V range and integrates a 5.0 Amp design, making it suitable for stationary HiFi systems as well as mobile installations. Visual feedback is provided by an RGB LED sound level meter that displays volume dynamically, and a front display screen shows operational status and settings in real time — ideal for listeners who value both performance and aesthetics.
