Voltage Stabilization, Rectification & Filter Power Supply System
* Complete DC voltage stabilization and filter power supply system
* The power system consists of a 35W power transformer, 4 high-speed rectifier diodes, 3 high-precision voltage regulators, 1 rectifier bridge, 6 imported capacitors and other components. It forms a power supply system that suppresses electric current ripples, safeguarding high-fidelity audio performance from the power source.
* It is an integrated power system assembled from a power transformer, rectifier circuit, filter circuit and voltage stabilization circuit.

High-Power Pure Copper Toroidal Transformer
* Abundant reserve power
* The CD player is powered by a high-power 35W toroidal transformer. Cooperating with the voltage stabilization and rectification circuit, it supplies independent power to digital and analog circuits separately. It delivers ample reserve power and achieves more efficient and reasonable power distribution, enabling stable reproduction of sound dynamics, details, texture and layers.

Rectifier Bridge/Rectifier Diodes
* Advanced power control technology for electric energy conversion
* Equipped with 1 rectifier bridge and 4 high-speed rectifier diodes
* High-speed rectification transmission rapidly provides sufficient voltage for circuits
* The rectifier circuit not only serves as the power source of the CD player, but also reduces voltage ripples to deliver steadier and cleaner sound.
