WIRELESS MUSIC ACCOMPANIMENT APPARATUS HAVING CONTROL FUNCTION OF AUDIO SIGNAL OUTPUT LEVEL

摘要

A wireless song accompaniment device with an audio signal output level control function is provided to cut down a manufacturing cost and to improve receiving and sending efficiency by mounting a single sending and receiving module in a main controller. A wireless song accompaniment device(500) with an audio signal output level control function comprises at least two wireless microphones(200a,200b,200n) and a main controller(400). The two wireless microphones converts an audio signal input from the outside to an electric signal and sends the electric signal through a wireless communication using an RF(Radio Frequency) sending module positioned inside. The main controller is formed with one RF receiving module receiving a signal from the two wireless microphones simultaneously through at least two receiving channels. The main controller receives the audio signal sent from the two microphones, mixes and outputs the audio signal with a kept accompaniment signal and a caption signal, and differentiates and outputs the level of an output signal according to the kind of an external device(100) to which the signal is output.
