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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
