power, efficient stereo amplification for demanding speaker systems. This Dual Core TPA3255 2channel Class D amplifier board delivers up to 600W + 600W and runs from a 19–50V DC supply, giving you powerful, lowheat performance in a compact board format. It is designed for builders and installers who need reliable, output amplification with the efficiency and precision of TI's TPA3255 architecture. Key benefits output power: Delivers up to 600W per channel when matched with an appropriate 19–50V DC power source, enabling strong, clean drive for performance speakers. Efficient Class D design: Digital Class D topology minimizes heat generation and power loss, allowing smaller power supplies and simpler cooling compared with traditional analog amplifiers. Stereo 2channel operation: True twochannel stereo output for left and right channels, suitable for stereo systems, active speaker builds, or bridging into mono configurations where applicable. Ready for DIY and integration: Board format simplifies installation into speaker cabinets, rack systems, or custom enclosures when paired with the proper power and speaker wiring. Key attributes Model and chipset: Dual Core TPA3255 design based on the TPA3255 digital amplifier architecture. Channels: 2channel stereo output. Power supply range: 19–50V DC input (ensure use of an appropriate, stable DC supply within this range). Output capability: Up to 600W + 600W total output across the two channels when used with compatible power and speaker loads. Form factor: Amplifier board intended for integration into DIY projects, speaker enclosures, or systems requiring a boardlevel amplifier solution. Typical applications and use cases power active speakers: Use this board to create or upgrade active speaker cabinets for live sound, studio monitoring, or output home audio where a dedicated DC power supply is available. DIY audio and custom installations: Ideal for builders assembling custom systems—floorstanding speakers, subwoofer modules, or multizone setups—when you need compact, efficiency amplification. Commercial or portable PA systems: Integrate into portable PA or installed sound systems that utilize a compatible DC supply and require strong stereo or bridged outputs. Installation and compatibility notes Power requirement: Operate only from a stable DC supply within the specified 19–50V range. Ensure the supply can provide sufficient current for the desired power output. Speaker matching: Select speakers and wiring that match the power capability and impedance compatibility of the amplifier to avoid damage and to achieve expected performance. Cooling and mounting: Although Class D efficiency reduces heat, appropriate mounting and ventilation are recommended for sustained power use. What makes this board unique Combines the proven TPA3255 digital amplifier architecture with a dualcore stereo board layout to deliver output per channel while keeping energy use and heat low. The boardlevel format gives experienced users flexibility for integration into custom audio solutions without the size and weight of traditional analog amplifiers. Includes One Dual Core TPA3255 stereo amplifier board (2channel, up to 600W + 600W, 19–50V DC) Ensure your power supply, speaker impedance, and wiring are matched appropriately before operation to achieve reliable, performance results.
