<p>A method and system are disclosed for controlling pop noises in a sound broadcasting system. After controllably connecting an output of a drive amplifier to a first predetermined low voltage level through a first switch, a first portion of an operation control data set is input to a digital-to-analog converter (DAC) circuit for driving an output thereof to a second predetermined low voltage level, and a second portion of the operation control data set is also input to the DAC circuit and further to the drive amplifier to bring the output of the drive amplifier to a common mode voltage level over a predetermined rise-up time period for controlling the pop noises.</p> |
