I've had two preamps that crossed over between channels. With music playing on 1 channel, but the amp/preamp set to a different channel you could hear the channel 1 music, slightly.
One of these products was the Audio Refinement Complete. The other will remain nameless.
Is this common? What's the cause? Is this a good test for quality? Can a product still be good or even excellent, yet exhibit this problem.
Follow Ups:
and you really shouldn't get much in a really good component. Typically, it is because the selector switch doesn't provide good isolation between contacts.
Solution? Mute non-active sources. Experiment with moving one source to another available slot and see if situation improves. Put shorting plugs in unused inputs.
Right, I understand how to fix it. What I was wondering is if it's a problem on all levels of gear (poor to excellent), or something you would never find on great gear.
I lived in a house built in the 90's once. If you flushed the upstairs toilet, people downstairs practically need to cease conversations as it was so loud. It's one of the first "tests" I do when shopping for a new house, now. And it has proven a good test of quality.
Kind of wondering if this talk issue is similar for audio...
...and it's been my experience that crosstalk is barely perceptible to non-existent on most decent preamps. Maybe barely perceptible in some only with the volume turned way up beyond normal.
As E-Stat mentioned, you can simply mute (or shut off) a source component that isn't being used, and put shorting plugs in unused inputs.
Some preamps automagically mute unused inputs (the equivalent of putting shorting plugs on all inputs that are not selected).
Does "The Truth" suffer from crosstalk?
Don't know about The Truth (don't own one, or have ever heard it), but I understand the guess.
