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.
