Abstract:
A karaoke amplifier for amplifying an audio signal to sound a karaoke performance according to music data while processing the audio signal according to a value of a control parameter to acoustically control the karaoke performance, the karaoke amplifier comprising:an analog operating member manually operable to set an initial analog value of the control parameter;an analog/digital converter for converting the initial analog value into a corresponding initial digital value;receiver means for receiving correction data contained in the music data from an external data source;memory means for memorizing the received correction data;calculating means for arithmetically treating the initial digital value according to the correction data retrieved from the memory means to calculate a corrected value of the control parameter;a signal processor for processing the audio signal according to the corrected value of the control parameter; andoutput means for amplifying the processed audio signal to sound the karaoke performance which is acoustically modified according to the corrected value of the control parameter.
