New equipment

[Hdale85]

Well I just got my new receiver today (new to me..looks brand new though). Its a Yammy RX-V2400, right now its hooked up to my Klipsch Promedia Ultra 5.1 speakers rather then useing their internal amp. The sound was deffinately improved from the internal amp. The only problem I currently hear is that I think I have a ground loop problem because my sub has a constant hum..... I live in an apartment so I can't really pull out the outlet and look at it. But I had it plugged into another outlet and I don't believe I had the problem. Are there any not so expensive ways to fix this?

Next week I should receive my new speakers which are 2 Klipsch RF-62's and the RC-62 center.

Well I found the problem...For some reason my Cable Box is causeing this hum...I've tried connecting it to the receiver through the composite video and s video and I still get the hum.

Search this forum for "hum" and related topics... lotsa info and solutions.

Ok I found some info on it. One of the solutions it looks like it says to cut the negative wire on the extra earthed device? Thats what it seemed to suggest.

You could try putting a cheater plug (3 prong to 2 prong) on one of your components and see if that helps.

Try disconnecting the cable from the cable box and see if the hum stops. If it does, call the cable company and have them fix the grounding on the cable.

It does stop when i disconnect the cable box from the receiver. But I read that ground loops happen when there are 2 different grounds in the connections. So the cable line is grounded to a different source then my outlets.

Have you tried an alligator jumper from the cable box chassis to the receiver chasis? This should bond them to the same potential providing one does not have an isolated grounded chassis.

What you need is a cable RF balun isolator- so that the noisy ground on the cable system is isolated from your system ground.

DO use the search- this problem has been discussed many times for many people.

Well the thread wasn't really about the problem just me talking about the new stuff I've purchased.


Which in the next few months I'll be getting a new T.V, hopefully some sort of next gen dvd player. Building a nice sub few other things like the rear surrounds and what not.
