FiiO PL50 Low Noise Regulated Linear Power Supply

About: FiiO PL50 Low Noise Regulated Linear Power Supply

Taking advantage of electricity for seriously good sound

A well-designed power supply is the foundation of good sound.And what is good for sound quality are linear power supplies,with their greater, high-quality and stable voltage output,smaller ripple, and lower noise.

The PL50, being a high-quality linear power supply, brings toyour sound a lower noise floor, more refined dynamics andtransients, and a more accurate, warmer tone to lowerfrequencies.

Compared to switching power supplies, the noise of linear power supplies is mainly low and fixed in frequency, which human ears are relatively insensitive to. In contrast, switching power supply noise is higher in frequency and can easily interfere with the analog portion of audio circuits due to radiation, directly impacting the output sound. Switching power supply noise can even indirectly affect the digital portion of audio circuits, further affecting sound quality.

In addition, the large PL50 is also equipped with a filter circuit on the AC end, for filtering out interference generated by other electrical devices being used on the same AC circuit for even cleaner and more stable power. 

Since the low-frequency noise of linear power supplies is fixed in frequency, this noise can be better and more accurately filtered out.

Fully optimized, solid parts

High-quality parts were chosen for every part of the design for higher and more reliable performance - such as the Shindengen bridge rectifiers, TI voltage regulator, and Nippon Chemi-Con and Rubycon capacitors

Completely considered design high-quality in operation

The PL50 features a complex circuit design that has been fully thought through to ensure reliable 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.

Dual voltage outputs one unit for multiple

The PL50 supports both 12V and 15V outputs, allowing it to match the voltage requirements of various FiiO devices. 

Metal construction continuing the FiiO design language

As with other products employing FiiO's industrial design, the outer shell of the PL50 is made of aluminum-magnesium alloy, which not only gives the unit a more refined texture, but also effectively shields the internals from external noise and interference.

Safety certified Assured reliability

This power supply has been designed and manufactured according to strict safety standards, and has obtained various international safety certifications – allowing you to be reassured of its reliability
