Will the tape/md out on my reciever cause line noise in speakers

[benJamin]

Have some Jbl sp6c in the celing they have that humm humm its high pitched.. the speakers are hooked up to a russound a-h4d key pad through 16gauge in wall speaker wire to a amplified key pad to cat 5 to reciever. Only the sub and the reciever and the a-bus system are plugged into ac.. I am useing the tape/md out on my reciever to hook it up to the russound system.. Any thougts to if this is why i have line noise in speakers is there an better way?

Aside from equipment failure, there's no reason the tape/md output should have any more noise than any other output. If the high-pitched sound is even the tiniest bit variable (i.e. not a pure sine wave) I might guess that the speaker lines are picking up something from the Cat-5.

should i be more careful

Should i be more careful in separating the cat 5 and the speaker wire in the junction boxes?

If there's any way to keep them at least a couple inches away from each other, do it! (I'm not familiar with most of this hardware and your setup, but if you can keep them in separate junction boxes, do so.) Otherwise, if they must intersect, do it at as close to a 90 degree angle as possible. Avoid running them parallel to each other at any reasonable cost.

Ill try the separation... What about an isolator?

Ground loop problem??

Probably RF/EM interference. Ground-loop requires electrical contact and is almost always 60 Hz or one of the 1st few harmonics.
