Audio Mini Digital Amplifier COAX/OPT Integrated 5.0 Amp Home/Car/Marine USB Player 24B/192K, Bass & Treble Control

Compact, feature-rich digital amplifier with COAX and OPT inputs and an integrated USB player supporting 24B/192K. This unit delivers flexible connectivity and on-the-go HiFi: it accepts five audio inputs (PC-USB & U-disk, stereo RCA, coaxial, optical) and offers three types of speaker output jacks plus a 3.5mm AUX preamp output and a 3.5mm headphone jack for private listening or expanded systems. USB functions include PC-USB (phone OTG) and U-disk playback of lossless formats WMA / WAV / APE / FLAC. Power comes from the Infineon MA12070 chip, providing up to 68W+68W output—enough to drive most desktop, bookshelf or indoor passive speakers rated 4-16Ω. The amplifier runs from a wide DC 9-20V range, making it suitable for home, car, motorcycle or marine stereo installations. A RGB LED sound level meter and display screen show volume/activity and operating status in real time, while onboard bass and treble controls let you tailor the sound. The 3.5mm AUX preamp output can connect an additional amplifier, active subwoofer, or active speaker to build a multichannel stereo setup.
