Home theatre sub

When sub is plugged into A.C outlet a lot of noise is generated thru the sub. When the sub is moved to a basement location no noise. As far as I can tell no noise is being generated by any electrical in the home.

Re: home theatre sub

Sounds like a ground loop issue. Try plugging your sub, and the rest of your entertainment equipment into the same outlet with an extension strip (4 plug adaptor). If there is too much stuff to plug into one strip, experiment with combinations and hopefully you will find which piece of gear is the culprit.

Hello Guys,Can you please help? can I replace the sub woofer on my sony home theatre system DAV-DZ231 with a Celestion sub woofer s10

Presumably, the Celestion subwoofer is self-powered in which case it would connect to an RCA subwoofer output on your Sony system if there is one.

How do i connect my subwoofer to my home theater

Easy. Your home theatre amp will have a sub or LFE output ( RCA plug ). You simply connect this output to the input ( usually the left side, or use a Y splitter and use left and right inputs, or the LFE input if your sub has it ). Then, you must turn the sub on in your recievers setup menu, and your sub should work.

I have brought a new Sherwood home theatre package with an RD-6505 Audio video reciever. The package came with a GSP5110SW subwoofer. We brought all the best cabling and connected it all up and it worked...

Disconnect that "best cabling" and see if the hum stays or goes away. If it stays, the issue is internal to the sub - likely a bad shield or ground point somewhere.

If it goes away, maybe a cable shield between the sub and the source is open, allowing atmospheric noise in. Swap or reseat it.

Have an existing ts-1100 home theatre infinity speakers

You cannot use this system with one that does not have a Subwoofer or LFE (Low Frequency Effect) output. Unfortunately, this sub doesn't have a line-level (speaker wire) input. Sorry.

Noise comming from centre speaker of panasonic scpt560 home theatre system

check the cable 1st. If this speaker is powered, you could have a bad shield, or the power is causing a ground loop.
If the speaker is coming from an amp using speaker wire ie: 2 lead + - check the connection and make sure no fraid strands are touching each other on the rear connection.
In addition check your TV, Ap, And speaker system (if sub is powered independently) are all on the same curcuit.
a certain cause for ground looping resulting in hum.

Burning smell

The amps do have issues that is for sure - That is where I step in - I can repair your amp and make it so it won't burn up (catch on fire) again. When the amp goes it burns a hole in the board - but it can be repaired. I have done several hundred and all customers are happy :) ... Look for my add here and also on ebay

I have no sound coming from home theatre system

I would check see if you can hear any hissing coming from the speakers if there's no sound then check to see if this product has output protection fuses and if so see if they are in tact if this doesn't solve the problem you may have dead outputs. If there is hissing coming from the speakers check your audio source to make sure it is feeding sound to your amplifier without looking its hard to say in these case's there's a lot to go wrong
