TAS5630 2.1 Channel Digital Power Amplifier Board (300W+150W+150W) HiFi DIY

High-power 2.1 amplifier board built around the TAS5630, with OPA1632DR and TL072 onboard for clean signal processing. Engineered for DIY HiFi enthusiasts, it delivers crisp, powerful audio performance suitable for demanding setups. Key components and audio path: fully shielded high-current inductors provide tight, powerful bass and reduced interference. The board uses five-ring metal resistors throughout, and the main circuit employs a five-ring metal film resistor with an accuracy of ±1% to preserve a high signal-to-noise ratio. Construction and reliability: PCB is a 1.6mm thick double-sided sheet with 2.0 oz copper and a full tin spraying process, ensuring excellent handling of both large and small currents—top-tier PCB quality. Power smoothing is handled by electrolytic capacitors 470UF/100V x 4 to supply strong and continuous power delivery.
