I 'm designing a sound system consisting of an audio source (say MP3) as an input to an amplifying circuit which will provide the output signal with a certain gain. This output signal will go through 3 speakers.
What I need to know is : can those three speaker be connected to only one amplifier circuit or do I need a circuit for each one ?
What are the elements in the circuit do I need to manipulate in order to control the output signal in terms of increasing and decreasing the volume of one speaker and without affecting the other 2 speakers ?
note : speakers are 8 ohms and 0.25 watt each just for testing ... larger speakers will be used eventually.
