switcher problem/ Question

[Magic2]

Hey this seems like a nice site. I hope I'm posting this in the proper forum

I have a concern. It sounds like there is music coming from my switcher. Is this normal???

Thanks
John.

Sorry about that.

I have a Niles Audio MSA-10 Impedance matching speaker selector. Amp is a B&K 200.2 I can hear music of some sort matching what is playing at the time coming from the transformers.
Any Ideas
