Loud humm. I have to keep the volume down when watching the TV.

I get a humm on my bose 28 system. Someone told me to install a fiberoptics cable between the cable box and the bose unit and this did not work.

A humm may be caused by a cable TV grounding problem called a "ground loop." Basically, the grounding for the Cable TV line and the power outlet for the TV are at unequal levels. I had this same humm with both the internal TV speakers and with external speakers (headphones, etc.). The 2 solutions are (1) install a Ground Loop Isolator at the TV, or (2) call the cable company to troubleshoot the problem. I figured the time I saved dealing with the cable company was worth the $50 for the part. I installed the Jensen VRD-1FF which has worked perfectly! Ordered from eBay and saved about $12 over the Jensen Electronics web site price. Hope this helps.

When listening to bose 321 system what should the volume of the tv be set at?


OFF. Unless the TV is the original source of what you're watching (antenna). Otherwise, your programming is probably coming from a cable/sat box with all the digital audio goodies, right?

If your TV has a menu for setting the volume out its RCA connections I would recommend you set it to whatever resembles FIXED, so it's volume control won't kill the stereo analog audio going out to the Bose. Then you can turn it off at the TV and listen through the Bose.

For the best multichannel audio you should get it digitally from the original source you're watching on the TV, but NOT from the TV itself.

Volume issue


The red/ white RCA is the most correct way for you.

Just to confirm it's analogue tv not digital you are watching?

Your friend is correct for when you watch from a settop box or pay tv provider you can run an optical cable to the bose -but- most tv's don't have an optical out.
SO- can I confirm that you can get sound out of just your tv on it's own?

I'd say that the audio outs on the back of your tv are "linked" to the tv's volume control, so you have to turn up the volume to get a louder output. Some tv's are advanced that you can disable the tv speakers, and permanentlyh set the tv output to a fixed level so you can use your surround sound (and Its volume control)
Try this one if you can.

You have to run an audio path with RCA cables from the TV (or the cable box, as applicable) to the Bose, then disable or turn down the TV volume.

I have a loud humm in my bose lifestyle 28 system


Turn on your bose so you can hear it hum. Go to the back of your cable box and remove the co ax cable connected to "cable in". If the humming stops, the sheilding on your cable is no longer grounded. Purchase MPAV800 or similar surge protector to run cable line through it and get it grounded.

Your Bose system doesn't lead sound trough hdmi.
You must connect the optical cable with your lifestyle.
Change the sound connectionsettings in the menu of your ps3.

You also need to assgn the optical connection in the setup menu of the lifesyle. e.g. optical=aux.

Lifestyle 38 and HD


I have also have this problem with a lifestyle 28 system. Bose sent me a new cable then a software update. The problem remained, after contacting Bose and unplugging cables and powering down the system this solved the problem. However 2 days after and the problem has re-appeared. Back to square one. I should add that this is the second unit I have had the retailer exchanged the last one because of the same problem.

Home Theater install


yes sounds about right what you are doing as long as you have 2 digital audio 'inputs' on your Bose to get the audio from the dvd player and cable box. Apart from your last part "I will then use Digital Audio from the Bose to the TV." The tv will only downrate the audio to two channel stereo, so its not worth puting audio through the tv as you only get stereo anyway, so might as well let the tvs speakers power it out themselves.
