About this item
- Massive 800W Peak Power & Dual TPA3223 ChipsExperience theater-like sound with our dual original Texas Instruments TPA3223 amplifier chips. Delivering a robust 200W + 200W + 400W (Left/Right/Subwoofer) output, this board thrives with a wide 12-42V DC input. Provide higher voltage for greater, cleaner power to drive demanding speaker setups.
- 6-Knob Studio-Grade Control & Full-Range OutputTake full command of your audio with six independent knobs: Sub Freq, Sub Vol, L/R Treble, L/R Bass, L/R Vol, and Master Vol. Precisely balance your subwoofer and stereo channels. The left/right channels feature full-range, unattenuated output, compatible with full-range, 2-way, or 3-way speakers for versatile setups.
- Triple Inputs & Physical Mode SwitchEnjoy versatile connectivity with Bluetooth 5.0 (stable connection), 3.5mm AUX, and USB playback (supports MP3, WAV, FLAC, APE up to 32GB FAT32). The dedicated physical switch makes swapping between Bluetooth, AUX, and USB modes instant and hassle-free.
- Comprehensive Protection & DIY ReadyBuilt for reliability and safety, featuring protection against short-circuit, over-current, over-temperature, and reverse polarity. Includes a pre-soldered ipex antenna and uses a standard 5.5x2.5mm DC jack. Its compact design is perfect for DIY audio projects, custom enclosures, or upgrading home theater systems.
- Smart Features & Package NoteFeatures one-touch control via the multifunction knob (play/pause, skip tracks, reset). The board includes power-on memory to recall your last used mode. Note: Power supply and audio cables are not included, allowing you to choose components that match your specific power and quality needs.
