loud hum insurrond sound Speakers.

[2_Peeps]

I have a loud hum through the surround sound speakers. The HR service center said it was being caused by the inverter. The inverter output is as per spec and they say it is operating satisfactorily. Has anyone experienced anything like this or have any suggestions on how to eliminate the problem.
I appreciate any input ou may have. Thanks.

iam not correcting anyone I simply said the HR came with good name brand inverters I did mix up ambassador with navigator my bad on that so buzz off

gutfelt, previously listed as hostage (banned), previously listed as usersmanual (banned). He knows everything and is not afraid to share. Just like a sore throat, can't get rid of him.

Perhaps. He has not answered, so we don't know for sure. He's already been told that.

well unless its been replaced HR ambassadors were top of the line so pretty sure it has a top line inverter also

Hard to believe I'm the only one here who posted about the inverter itself. Easy to verify... if there's no hum on shore power, then it is almost without a doubt the cheap inverter.

But so far no response from OP.

It's likely a ground loop fault. Get some better cables and check all your connections.

I've used the better quality Monoprice cables with good results. A pricier upgrade would be Blue Jeans Cables.

OP?

Well, in MD11s we had a 60hz hum, we installed diodes in it. Did not stop it but dropped the volume about 30 decibels.

Long-time audiophile here.....the majority of "hums" in sound systems is because of bad cables/connections causing bad grounds which ultimately allow a 60Hz electrical signal to enter the cable and be amplified to where you can hear it. If your speaker cables are not shielded, they should be. Other causes in home stereo systems are variable dimmer switches and bad house grounds or other improperly grounded appliances plugged into the same circuit as the audio system. In rare cases, it can be external RF signals from close-by radio sources like wi-fi hubs.

Cheap MSW inverter.

Bad grounds are often the cause of hums.

[dons2346]

Low battery voltage will cause this

On my home system we had a hum coming from the sub woofer. Cause was a cheap house brand cable from Best Buy. Purchased a better cable and that fixed the problem.
