FiiO Darkside Pro | Low-Noise Regulated Linear Power Supply

FiiO is Proud to Introduce Their Power Purification Series with the Darkside Pro, Offering an Ultra-Silent, Pitch-Black Background to Let Your Music Shine
- Audiophile-Grade 75W Toroidal Transformer
- 12V/15V Dual Voltage Support, 3A High Current Output
- Fully Discrete Voltage Regulator Circuit + Dual-MOSFET Parallel Current Amplification Output
- Self-Resetting Fuse Overcurrent Protection
- Precision Potentiometer for Voltage Fine-Tuning

75W Toroidal Transformer
Specifically designed for low-noise audio, this toroidal transformer utilizes a grain-oriented silicon steel circular core process for higher efficiency and minimized eddy currents. The seamless, fold-free coil design ensures a uniform magnetic field and minimal magnetic leakage. With a 75W reserve, it effortlessly handles high-dynamic transient demands, delivering solid bass extension and a vividly clear soundstage.
Audiophile-Grade Components
Japanese Shinengen D15XB60 Bridge Rectifier
Low heat generation and high stability minimizes micro-interference caused by current fluctuations for a cleaner audio signal.
5 ELNA Capacitors + 7 Rubycon Filter Capacitors
Effectively filters power supply noise to reveal a crystal-clear sonic foundation.
Mono-Crystalline Silver-Plated Copper DC Cable
Reduces transmission loss and shields against electromagnetic interference (EMI) to enhance audio details.
Fully Discrete NMOS Voltage Regulator Circuit
Dual high-current IRFZ34NPBF MOSFETs are used in a parallel configuration to lower internal resistance. The result is improved dynamic range and assurance that every nuance of audio is faithfully preserved.
Relay-Switched 12V/15V Output
An integrated relay manages the transformer's output voltage to provide a precise match for both 12V and 15V settings. Such a design maximizes power efficiency and significantly reduces heat generation during operation.
