CONSTITUTION: An audio mixing device(100) includes a signal processing unit, a signal controlling unit, a digital signal outputting unit and a Bluetooth/Zigbee communication processor. A digital amplifier(200) amplifies and outputs a digital broadcast single outputted from the digital signal outputting unit and performs Bluetooth or zigbee. A speaker controlling device(300) controls a speaker which will output a digital broadcasting signal and outputs the digital broadcasting signal to a speaker, and perform the Bluetooth or Zigbee communication. |
