FIIO JadeAudio/FiiO PL50 Low Noise Regulated Linear Power Supply 12V/ or 15V Output for USB DAC HiFi Amplifier/Music Player M17

[Custom high-quality transformer]: Inside the PL50 is a custom 50VA audiophile-grade toroidal transformer, made of high-quality Nippon Steel iron and high-purity oxygen-free copper wires for higher efficiency, higher precision, more stable voltage, and for higher energy output. [Seriously good sound]: The PL50, being a high-quality linear power supply, brings to your sound a lower noise floor, more refined dynamics and transients, and a more accurate, warmer tone to lower frequencies. [Dual voltage outputs]: The PL50 supports both 12V and 15V outputs, allowing it to match the voltage requirements of various FiiO devices. [High-quality in operation]: EMI filtering, transformer rectification, voltage regulation sampling, and multi-stage filtering are all parts of the circuit design so that you can use the PL50 without worry. [Digital display]:The clear digital display distinctly shows the current voltage, letting anybody easily know what is happening with the power supply.
