FiiO DARKSIDE PRO 12V/15V Low-Noise Regulated Linear Power Supply
The FiiO DARKSIDE PRO is a high-performance linear power supply engineered to deliver an ultra-silent, low-noise power source for sensitive audio equipment. Designed around a 75W toroidal transformer and fully discrete regulation architecture, it provides a pitch-black background that allows fine detail and dynamic expression to emerge naturally.
With selectable 12V or 15V output, high-current MOSFET regulation and precision voltage fine-tuning, the DARKSIDE PRO is built for demanding desktop audio systems. Its robust construction and carefully selected premium components ensure stable, clean power with minimal ripple and reduced electromagnetic interference.
