Special Features
【Dual TPA3255 Chips for Massive 2.1 Output】Built with two genuine TPA3255 Class‑D amplifier chips, this board delivers powerful stereo and subwoofer channels. Maximum output reaches 300W × 2 for left/right (4Ω) and 600W for the subwoofer (2Ω) – enough to drive large passive speakers, subwoofers, or a full home theater setup
【Three Independent Input Modes (BT / AUX / USB) 】Switch easily between Bluetooth 5.2, 3.5mm AUX, and USB input. The USB port supports FAT32 flash drives (up to 32GB) and plays WAV, FLAC, APE, MP3. It also works as a USB sound card when connected to a computer. Bluetooth is the default mode on first power‑on.
【Wide DC 19‑51V Power Range & Built‑in Protections】Operates from 19V to 51V DC (10A or higher power supply recommended). Higher voltage unlocks higher output – refer to the output power table in the manual. Integrated protections include short‑circuit, over‑current, over‑temperature, and reverse polarity to help prevent damage under normal use
【DIY‑Friendly Panel Design】The board comes with a pre‑cut DIY panel, allowing you to mount the amplifier into a speaker box or enclosure without drilling holes. All interfaces (power, speaker terminals, input selector, and volume knobs) are clearly labeled for easy wiring
【Important Power Note for Best Performance】To achieve the rated power output, use a DC power supply within 19‑51V with sufficient current (≥10A). The actual output depends on the supply voltage and speaker impedance. Avoid operating the amplifier beyond recommended conditions to ensure stable performance and longevity
