Audio signal help?
Amplifier with Gain = 20
From this datasheet But I have no Idea how to put the signal on.
I think that the signal is Vin (pin 3) but that is one cable when a headphone has three cables. I know the red wire is right and the blue is left and the other is comm so I onley need 2. Because there is one input I need to make it one cable. Would this work (I will test what resistor I need with a voltmeter later).
If I am wrong about there olny being one input can someone explane to me how to wire it.
