I have four Beolab 6000 speakers and a sub-woofer. How can I use these with a Sony or Panasonic TV system?

That would depend on the unspecified 'TV system' and its speaker requirements and controls. Most TV's don't support directly-attached speakers. Since these are self-amplified, half the battle is won.

Have you looked at any manuals?

The Beloab 6000 speakers DO support connection to non-B-and-O products through the RCA Line In jacks but that presumes you have external volume control.

The unnamed subwoofer probably won't work with a TV. More details would be needed.

This speaker system would work with any 'standard' component-style system if you wanted to use them for the TV AND other sources.

I ended up with one piece of a Teac model CD-X8 MIcro Hi Fi System. you can see what the whole system looks like at

Yes - you have the sub-woofer. It is a powered sub-woofer with a built in amplifier for both itself and a pair of small satellite speakers. Frankly, given the low cost of the whole system it may not be worth selling on ebay due to the high shipping costs of such an item, but I imagine you could get $30 for it or so on local craigslist or something, assuming you have no use for a sub-woofer...

Hi, I have a rumbling noise coming from the sub woofer on my surround sound system. Any ideas?

Is it only at high volume or all the time? It could be that your input from your DVD may be bad.

Volume is too loud

change the function to cd or aux before you turn it off and then change the volume before going to your preferred function. It is the only way around it.

Power shuts off

The unit is in "protect" mode. Basically a problem is detected in the last output stage of the amplifier section and the unit shuts down to prevent further damage. I suspect that you connected too many speakers to the system. The impedence load was too low for the amp section to handle and one or more output transistors have failed. This should be a straightforward repair for any local repair shop. Figure on $20-$40 for parts plus the local labor rate for the repair. I am not familiar with your specific model, but these shelf units are all similar in design. I will try to locate the service manual for this one to get you more details.

Problem w/shelf system stereo system!!!!!!!!1

You say that the fault lies in the sub-woofer speaker....

You will need to remove the back panel of the speaker box and make a visual examinatiojh of the contents there just may be an overload fuse there that you can replace your self...there may be a broken wire if the Sub-Woofer has been dropped...

There may be a capacitor or choke that has come loose from its mounting and in falling broken a wire,,,but please have a good look to see whats gone wrong inside the sub-woofer cabinet.

If you like you could take the backs of both the right and left
sub-woofer speaker boxes then visually compare the good one with the faulty one so you can see if there is any physical difference on the faulty one...if they both look the same then you willl need to do some testing with a multimeter set to Ohms to see where the break in continuity lies...just compare readings between the good one and the faulty one to find the fault..

CDs won't play

Maybe you should fix the cds or clean them or try to fix the disc reader in the radio.

Turning the Alarm Volume up

try keeping the system off for over 2 weeks as this fully resets the whole systems memory (this does make you loose your radio preset's and any other tweeks you have done to it) but with a reset unit it should fix its self

Power cuts out

This problem happend to my sony system about a year ago. It was the amp that blew in mine because of the fan inside the system was not coming on when it should of. I found that when i had put my PC in the AUX jacks it blew the fan on me, so every time the volume got to 15 the system would just shut down and not come back on at all, or it would need time to cool down before it would start up again. Take it to a shop and get it looked at by someone that knows what there doing. Please dont try and do this yourself.
