Dualchannel power amplifier board built with two TI TPA3255 modules for clean, efficient stereo amplification. Ideal when you need low distortion, precise channel separation, and reliable operation across a range of speaker loads and power supplies. Key benefits Accurate stereo reproduction: dual TI TPA3255 amplifier modules plus shielded, lowloss inductors and imported capacitors deliver channel separation and minimal distortion for clearer imaging and detail. Flexible power compatibility: accepts 19V–52V input so you can use a variety of power supplies for different installations and wattage needs. Wide speaker support: stable 20Hz–30kHz frequency response across 2Ω / 4Ω / 8Ω loads, compatible with most bookshelf, floorstanding, and studio monitor speakers. Thermal and longevity protection: thermalprotective PCB construction and quality component materials reduce overheating risk and extend hardware life through smart energy management. Efficient performance: engineered for efficiency to reduce waste heat and maintain reliable roomtemperature operation during normal use. Installer and DIYfriendly: boardlevel layout and componentgrade parts make it suitable for professional installations or custom amplifier projects. What it does for you Keeps music and voice clear with low distortion and tight stereo imaging. Lets you configure power supply options to match your system and available transformers/adapters. Provides stable response and safe operation with common speaker impedances, reducing guesswork in installation. Typical use scenarios Home theater upgrade: drive left/right channels for a compact home theater system, improving clarity and dynamics without extensive cabinet modifications. DIY stereo build: integrate into a custom amplifier enclosure for audiophilegrade desktop or livingroom systems using preferred power supply and connectors. Small studio or livesound applications: power nearfield monitors or a small PA pair with reliable frequency response and thermal protection for longer sessions.
