A BROADCASTI2G SYSTEM USI2G PLURAL AMP WITH AUTO-SWITCHI2G

摘要

PURPOSE: A broadcasting system using a plurality of amplifiers including a switching function is provided to improve equipment efficiency by eliminating a separation between a main amplifier and an auxiliary amplifier. CONSTITUTION: A first main amplifier(200) and a second main amplifier(300) are respectively connected to a source device. An auxiliary amplifier(400) supports the first and the second main amplifiers. Signals of the source device are amplified in the first main amplifier, the second main amplifier, or the auxiliary amplifier. The amplified signal is outputted through a speaker connected to the source device. A first input switching unit is respectively connected to the first main amplifier, the second main amplifier, and the auxiliary amplifier.
