The protection circuit requires a separate power supply (AC 12-18V, a separate winding must be used

Group, cannot be shared with others)

 package include：finished amplifier board with heatsink*1

Newly designed high-power dual channel high fidelity amplifier board, suitable for household and stage use

Used, with full power, clear and powerful sound quality, pure, and clear and delicate tone,

After input differential amplification, push the medium power transistor, and then push the original Sanken transistor

2SA1494/2SC3858 amplifies power output, and the power amplifier board is designed with dual channels

Each pair of 200W ultra high power transistor outputs greatly enhances the effect

Full thrust, strong enough, with new and original pipes selected to ensure sufficient pressure resistance

The effect is stunning, the force is extraordinary, the circuit design is optimized, and the switch is integrated

Machine mute, over temperature protection, overload protection, high overall noise to noise ratio, installed

Almost no noise can be heard
