Step 14: How to get sound out of iPod (1)

OK, we need some sound out of this thing somehow.
The iPod thinks it is connected to an external device via a docking station. Therefore it sends its audio out the "line-out" pins NOT the iPod headphone socket.
The line-out audio is wired up to two phono sockets shown here. A suitable cable with two phono plugs on each end is then used to connect it to a HiFi amplifier if that is what you want to do.
You can connect the line out wires to a headphone socket, and indeed I have run them from these line-out phono sockets to a headphone socket, but it is very loud, hence the presence of the two 10K Ohm potentiometers to adjust each side of the headphone volume.
