Signal Leak

[brisrascal]

I have a problem with signal leak. My current setup is as follows:

HK TU9400 Tuner
HK 6550R Amp
Audio Technica ATH5000W
(Use it in the office so no speakers)

Anyway, i have connected the tuner to the tuner input and i recently connected another source in from my notebook. The problem is that I can detect a signal leak whenever i switch from one source to another. Every time I switch from my tuner to another empty input, I can detect through the phones a very weak signal from the tuner. However when the input switches to one with a signal coming through, the tuner signal disappears. Can anyone give a insight as to the cause and solution? Cheers.

You have what is called cross-talk and it appears that the unit is not as discriminating as it probably could be.

Also, with that headphone you are more isolated from background noises and are able to detect at a lower level. When there is no signal on that other source the radio is more noticeable since it has no competition to with louder signals and nothing to mask it with.
I doubt you can do much about it short of other components, turning off the radio when not in use.

So being that the unit is susceptible to crosstalk. Is there any way to minimize it? Would using shield cables make a discernible difference? I have two inputs currently, one using a shielded coax. one unshielded pair.

Cross talk in this case is internal design. No external solutions nor internal.
