Mono 200W power amplifier board 1943 + 5200 rear power amplifier board

High-Power 200W Mono Amplifier Board: Professional-grade power amplifier delivers 200W RMS output for driving subwoofers, large speakers, and high-SPL applications. Perfect for dedicated subwoofer amplification, active speaker systems, and multi-amplifier home theater configurationsprovides punch and authority for bass-heavy content.
Classic 2SA1943 + 2SC5200 Transistor Pair: Built around legendary Toshiba 2SA1943 (PNP) and 2SC5200 (NPN) complementary power transistors renowned for audiophile-grade sound quality. Low distortion and wide bandwidth deliver clean, powerful basstrusted choice for professional audio and hi-fi amplifier designs.
Bridgeable & Expandable Design: Single mono channel allows flexible system configurationuse one board per subwoofer, bridge two for stereo, or stack multiple boards for multi-channel systems. Independent amplifier per speaker eliminates channel crosstalkideal for bi-amping and tri-amping configurations.
Heavy-Duty PCB Construction: Thick copper PCB traces handle high current loads with minimal voltage drop. Large heatsink mounting area ensures efficient thermal managementreliable continuous operation at high power levels for demanding audio applications.
Versatile Applications: Perfect for DIY subwoofer builds, car audio systems, PA amplifiers, home theater power amplification, and active studio monitors. Works with balanced and unbalanced inputsprofessional solution for custom audio projects requiring dedicated high-power mono ch
