Mini Digital HiFi Class D Power Amplifier — Bluetooth 5.0, 50W*2, USB & TF-Card, for Home Theater / Car / Marine

Compact, versatile mini amplifier with modern features for home, desktop, car or marine use. Wireless audio is handled by Bluetooth 5.0 with lossless transmission for a stable connection and extended range (up to 12m unobstructed); it is intelligently compatible with 99% of devices. Pure copper gold-plated terminals improve signal stability and transmission accuracy. The unit’s one-piece plastic case and LED display deliver a smooth, screw-free exterior and a premium feel, while the built-in ring gauge visually reacts (‘dances’) to the music. Multiple inputs are supported (aux / USB / Bluetooth / TF-Card) so you can play from nearly any source. The USB port works with computers (without driver) and with mobile phones that have OTG function (with OTG function). The front-panel volume control uses a high-quality encoder rather than a conventional potentiometer to prevent adjustment noise. Engineered for high-fidelity playback, the circuit is optimized to eliminate audible noise even at maximum output power (100w*2), and it can drive most home speakers. Lightweight and space-saving, this mini Class D power amp offers big sound and flexible connectivity at an affordable price.
