Abstract
A karaoke amplifier is constructed for amplifying an audio signal to sound a karaoke performance while processing the audio signal according to a value of a control parameter to acoustically control the karaoke performance. An analog operating member is manually operable to set an initial analog value of the control parameter. An analog/digital converter converts the initial analog value into a corresponding initial digital value. A receiver receives correction data from an external data source. A memory memorizes the received correction data. A calculator arithmetically treats the initial digital value according to the correction data retrieved from the memory to calculate a corrected value of the control parameter. A signal processor processes the audio signal according to the corrected value of the control parameter and amplifies the processed audio signal to sound the karaoke performance which is acoustically modified according to the corrected value of the control parameter.
