MUTE APPARATUS AND METHOD OF POP NOISE FOR LEARNING SYSTEM

摘要

A device and a method for removing pop noises in a learning system by remote control are provided to remove the unpleasant pop noises by performing mute operation before power-off of a power amplifier even if learning devices and the power amplifier are turned on or off at the same time. An amplifier system(400) receives an audio signal from a learning system(300) including a plurality of learning devices. The amplifier system amplifies the audio signal to a predetermined signal level. A control system(100) includes a controller(200). The controller outputs a control signal for successively control power-on or off of the learning and amplifier system. The control system sets up a power-on or off control mode to power supplied to the learning and amplifier system through the controller.
