The HIFI Bluetooth music amplifier is designed as class AB with full structure of separated components and parts, and scientific, rational PCB layout and strict sound adjusted so that it performs distinctive sound. And add distortion servo circuit in the circuit design, so when large dynamic come, its performance is leisurely, unhurried. Meanwhile, its amplified circuit adopts NE5532 as a preamp, and T oshiba tube as power amplifier stage, these two parts complement each other. In addition, it builds amplifier speaker protection circuit inside to protect your speakers. Cooling system is made of blackening treatment process of heat sink, and a fan that connected with heat trace wire to the heat sink with forced cooling.





Brushed aluminum panels, black metal housing, it is noble and elegant. It is adopted that transformers toroidal with all copper, high efficiency and low leakage, which provides powerful current, thus providing better, more pure sound. As a HIFI Bluetooth desktop amp, front panel has a third selection for signal input, Bluetooth / PC / AUX; and there is tremble and bass knob for tone adjustment and AUX input jack.


Also there is bass and tremble adjustment knob on the front panel.




1.    PCB adopts double-sided design, so the amplifier is stable and reliable.

2.    Resistors with high precision metal film resistors, capacitors capacitance meter level precision.

3.    Filter capacitor with high-speed, low-loss high-capacity capacitor.

4.    Gold-plated RCA and terminal, so that the sound transmission is more smooth, pure.

5.    Setup bass and tremble adjustment knob on the front panel.
