Default Selector Switch Pop - Newbie Question

I have searched the forum, but cannot find an answer to my problem.

I wired up a three way Goldpoint stereo selector switch to select the source for my power amp. The switch is break before make and I am switching both the signal and ground wires.

My problem is I get a loud pop when I switch from one source to another. I'm sure if I tied the grounds together that would solve my problem, but I have read that switching both the signal and ground is the proper way to do a selector switch.

Any help is greatly appreciated.

Lindsay

I think it's more usual to have a "make before break" type for this application. Someone correct me if i'm wrong.

The Goldpoint distributor insisted that a selector switch should be break before make. I had asked for make before break and they do not have that type of selector switch.

If it pops you have some DC on it. Shunt it's output to ground by a resistor, it should help. And be sure your signal sources has no DC on outputs. Also, I would not switch ground wires.

Thanks Wavebourn. What value resistor should I use for the shunt to ground?

I've appreciated reading your posts on the John Curl Thread.

Thanks!

As soon as the majority of modern equipment have around 100K inputs I assume 470K will add inaudible losses.
