CIYISON 500W Mono Power Amplifier Board — High-Fidelity Single-Channel DIY

CIYISON's 500W amplifier board delivers robust, studio-grade sound and is capable of producing stereo reproduction while easily driving 15inch speakers. The design relies on heavy-duty power trios A1943/C5200 alongside A1837/C4793 power transistors to maintain thermal stability during prolonged high-volume operation. Signal processing uses a double differential A970/C2240 stage with an A1145/C2705 voltage amplification section, and the board accepts a supply range of DC20V 90V for flexible installation. Suited for audiophiles and hobbyists, it’s made for home theater systems, powerful stereo rigs, live music setups, and immersive cinema applications that require low-distortion output. Engineered with a modulars monoblocks design for straightforward integration into premium speaker systems.
