THE PUBLIC ADDRESS WITH THE WAY INSERTING A DISITAL AMP IN SMALL QUANTITY

摘要

PURPOSE: A small-capacity insertion-type digital amplifier broadcasting device is provided to remove noises caused by the thermal noise of a conventional power transistor by using a small-capacity amplifier which emits small heat. CONSTITUTION: A small-capacity insertion-type digital amplifier broadcasting device comprises a small-capacity insertion-type power amplifier, an amplifier socket, a relay group, a speaker, and a main control unit. The small-capacity insertion-type power amplifier is made of an digital IC(Digital Circuit) amplifier and comprises an amplifier socket. The amplifier socket has a combination groove. The relay group consists of N×N dot matrix circuits.
