Clean, Stable Power for Your Audio Equipment

The FiiO DARKSIDE MINI is a compact noise-reduction power supply designed to provide clean and stable 5 V power to compatible audio and digital equipment.

Developed specifically for high-fidelity audio systems, the DARKSIDE MINI combines intelligent noise-suppression circuitry with an optimized transformer to reduce electrical interference before it reaches the connected equipment.

With noise reduction of up to 40 dB and a stable 5 V / 2.5 A output, it provides a simple solution for improving the quality of power supplied to compatible DACs, streamers, and other digital audio devices.

Intelligent Noise Reduction

Rather than relying solely on conventional filtering systems, the DARKSIDE MINI uses an intelligent control chip to manage the output current waveform.

The system actively works to reduce unwanted electrical interference, helping provide a cleaner power supply and minimizing the potential influence of power noise on sensitive audio circuitry.

FiiO rates the DARKSIDE MINI for noise reduction of up to 40 dB.

Quiet and Efficient 5 V Power

The DARKSIDE MINI provides a stable 5 V / 2.5 A DC output, giving compatible Hi-Fi equipment a consistent power source while ensuring quiet operation.

Its compact format makes it particularly suitable for desktop audio systems where a larger dedicated power supply may be unnecessary or impractical.

Optimized Transformer Design

FiiO has optimized the internal transformer structure to reduce fluctuations and interference within the power supply.

Combined with the intelligent noise-reduction circuitry, this enables enhanced dynamic noise suppression and helps prevent unwanted electrical interference from affecting the audio signal.

The result is cleaner and more stable power for compatible audio equipment.

Wide Compatibility

A standard 5.5 × 2.1 mm output is complemented by a selection of supplied adapters, allowing the DARKSIDE MINI to power a wide variety of compatible devices.

The included adapters provide:

• USB Type-C

• USB-A

• DC 3.5 × 1.35 mm

• DC 4.0 × 1.7 mm

This makes the DARKSIDE MINI particularly useful for digital audio equipment featuring different types of power-input connections.

Compact Desktop Design

Measuring approximately 71 × 44 × 42.5 mm, excluding the AC plug, and weighing approximately 133 g, the DARKSIDE MINI incorporates its power conditioning and noise-reduction system into a compact wall-adapter-style format.

Its small footprint makes it easy to integrate into a desktop Hi-Fi system without adding another large component to the setup.
