PROBLEM TO BE SOLVED: To optionally adjust the sound volume of background vocal, outputted as MPEG(moving picture coding expert group) data from a communication Karaoke sing-along machine terminal equipment, by the operation of a singer or the like. SOLUTION: When a tune number is inputted from a remote controlled transmitter 5, this signal is received by a remote controlled receiving part 4, converted into an electric signal and inputted to a CPU 6. The CPU 6 reads the data of a tune of an assigned number from an HDD 2, inputs the tune data to an MIDI decoder 7 to decode it, and inputs the voice data of background vocal or the like to a voice MPEG decoder 8 to decode it. When the adjustment of sound volume of background vocal is inputted from the remote controlled transmitter, this signal is stored in an MPEG sound volume storage part 9. This signal is read out, and a sound volume adjusting part 10 is controlled to adjust a signal level from the voice MPEG decoder. Signals from the MIDI decoder and sound volume adjusting part are analog-converted by analog-to- digital converting parts 11, 12, mixed by a mixing part 13 and acoustically outputted through an output part. |
