Description:

This series is an innovative audio power amplifier. It adopts TD-type circuit design technology while maintaining the excellent sound quality of the AB-type output stage. Heat dissipation is introduced into the wind tunnel-type air guide system, and all output stage transistors are fixed vertically to the airflow to achieve the best heat dissipation mode. Perfect audio coupling circuit, which makes the sound transparent and sweet. Perfect and precise protection circuit which is more effective to protect the amplifier and speakers from harm. The use of advanced SMD patch and laser scanning and other automated manufacturing processes, and the selection of super-first-class semiconductor components greatly improve the reliability and consistency of the product.We fully consider the use of entertainment private rooms and multiple coal bodies to enhance competitiveness and practicability. The amplifier is designed for entertainment and sound reinforcement for hall meetings.
