The heart of this digital volume controller DVC circuit is IC2 4067, 16-channel analog multiplexer. Because the 1kΩ has been connected between every input and output, the multiplexer can act like a ...

this is a stereo preamplifier circuit and through this we can control bass, treble and volume of the sound signal in a very professional way. This circuit has good frequency response. All the ...

A monolithic IC which contains dual-channel volume control circuits, tone control circuits, and function switches is discussed. The IC has excellent characteristics, such as total harmonic distortion ...

The capactiors C1 and C4 are very important in the circuit: they prevent the IC1 from oscillating. Simultaneously closing both switches will not damage the circuit. Touch volume control circuit ...
