Technical Highlights:

  • Ultra-Low Noise Regulation: Precision voltage reference + high-speed op-amp + MOSFET power transistors for stable and clean power output.
  • CLC Filtering System: Triple-stage input/output filtering for significantly reduced ripple interference.
  • High-Current Rectifier Bridge: Heat-resistant and high-current tolerant for long-term stable operation.
  • Custom Transformer: Japanese core + high-purity oxygen-free copper winding for efficient energy transfer.
  • Low-Impedance MOSFET: Effectively suppresses AC circuit interference, improving dynamic performance.

Key Advantages:
✔ Ultra-low ripple (≤9μV) – Minimizes current noise and reduces harsh high-frequency distortion.
✔ Wider dynamic range – More stable soundstage and enhanced detail retrieval.
✔ Multi-device compatibility – Supports MAC MINI, NUC, routers, and other Hi-Fi equipment.
✔ Handcrafted construction – Precision soldering by engineers for superior build quality.
✔ Ground switch (ISOLATED/GND modes) – Adaptable to different device requirements.

  1. Connect Your Device: Plug the power supply output into your audio/video equipment (e.g., DAC, network switch).
  2. Select Grounding Mode (Optional):ISOLATED (Default): DC negative terminal isolated from AC ground to prevent ground loops (ideal for most setups).GND Mode: DC negative connected to AC ground for devices requiring direct grounding.
  3. Power On: Switch on the unit and monitor the output voltage display to ensure proper operation.
  4. Fine-Tuning (If Needed): Adjust voltage (±2.5%) for optimal performance based on your equipment.
