RE: selector switch, leave out?

First, one of the enhancements of the FP III over the FP 2 is the selector switch. It switches the Signal Ground of each input as well as the Signal Hot when switching. This eliminates a source of hum.

Answering your question, it will not work as well as you think. Each source, CD/Phono/Tuner, has an output impedance (resistance). All of them hooked up at the same time, even with two of them off, are paralleled. That causes an interaction.

Say you are playing your CD player. Not only does it feed into the input resistance of the FP III but it also tries to "drive" the output of the phono preamp and the tuner too. This will cause distortion that you don't want.

And finally, if you don't want to use the input selector switch, the best way to do that is to swap input cables when you want to swap inputs.

I would use the selector switch. It is a good one.


Remember, YOU are the only one who needs to be happy with the sound of your system
