1pc Dual Core TPA3255 Stereo Amplifier Board — 2Channel Class D, 600W + 600W (19–50V) Bring power, efficiency amplification to your custom audio projects. This dualchannel digital Class D amplifier board uses the TPA3255 architecture to deliver up to 600W per channel when supplied with the appropriate DC voltage and current. Designed for DIY builds, professional installs, and compact power systems, it provides a powerful, efficient foundation for driving passive loudspeakers. Key benefits output power: Up to 600W per channel for demanding speakers and large rooms. Efficient Class D design: Reduces heat and power waste compared with linear amps, letting you build smaller, more efficient systems. Wide supply range (19–50V): Flexible integration with a variety of DC power sources and commercial power supplies. Compact board form factor: Easier integration into custom enclosures, active speaker cabinets, or retrofit installations. Versatile stereo operation: Two independent channels for left/right stereo or bridged/biamp configurations (confirm wiring and supply requirements for bridged use). Main features and specifications Model: Dual Core TPA3255 stereo amplifier board Channels: 2 (stereo) Power: 600W + 600W per channel (as specified) Amplifier class: Class D (digital power amplifier) Operating voltage: 19–50V DC Package: Single PCB module (1pc) What makes this board useful Powerful output in a compact module: Delivers continuous power while keeping size and cooling needs lower than equivalent linear amplifiers. Flexible system integration: Works with a range of DC supplies and is suitable for custom speaker enclosures, installations, and conversions. Straightforward for builders: Boardlevel access to power and speaker connections simplifies wiring for experienced DIYers and installers. Typical applications DIY active speaker builds: Create power powered speakers or upgrade passive cabinets into active systems. Small PA and performance systems: Drive monitor wedges or compact main speakers where output and efficiency matter. Home theater and media rooms: Use as a power amplifier for subwoofers or left/right channels in a custom audio setup. Installation and compatibility notes Power supply: Requires a stable DC supply within 19–50V. Ensure the power supply can deliver sufficient current for your speaker load and desired output. Cooling: Although Class D is efficient, adequate ventilation or a heatsink is recommended for sustained power use. Speaker matching: Match the amplifier output to passive speaker impedance and power handling. Confirm wiring and load requirements before operation. Professional handling: Boardlevel modules are intended for users comfortable with electronic installation and wiring. Follow safe wiring practices and disconnect power before making changes.
