Abstract (en)

There is provided a music accompaniment apparatus that includes: at least two wireless microphones for converting externally input audio signals to electrical signals and sending the electrical signals using a built-in RF transmitter module through a wireless connection; and a main controller having one RF receiver module capable of simultaneous signal reception from the at least two wireless microphones through at least two receiver channels, receiving audio signals from the at least two wireless microphones, mixing the audio signals with embedded accompaniment signals and caption signals, and sending output signals with an output level varied according to the type of external equipment used as an output target. The music accompaniment apparatus reduces the production cost, enhances transmission/reception efficiency, and reproduces audio signals of the best audio quality without distortion.
