The use of an audio pre-amplifier ensures good audio quality and provides options to modify our sound system by using this as a primary audio circuit/device before feeding the audio signal to your amplifier/subwoofer/home theatre system. Also, we can control bass and treble for different songs and get a wide range of control over our audio system. This type of circuit that provides Bass and Treble control is also known as a BT Circuit Board. In this article, we will build a stereo pre-amplifier circuit with bass and treble control.
