BeoCenter 9500 + BeoLab 5000 + PowerLink = Data, but no audio...

20 replies

Hi,

Just recently I have bought two BeoLab 5000 speakers, to go with my BeoCenter 9500. For the time being I have had them connected using SpeakerLink cabels, which worked fine, but of course, no data on the display, and in passive mode.

Today my PowerLink cables arrived (

Have you switched the speakers to Audio? They may be set to Video. Not sure about the powerlink cables - you need fully wired ones for the Beolab 5000 and the ones pictured look thin - but you did say the displays were working.

Hi Peter,

Thank you for your reply.

Can you tell me how I switch them from Video to Audio? I can't seem to find any switch to do so.

The displays are working, and I did purchase "fully wired" cables, so it seems to me they should do the trick

 (Also, as I mentioned, one of the speakers played for 10 secs when I connected it, but just stopped and never played again through powerlink)

The cables do not look to be correct. You need Mk2 fully wired powerlink cables for speakers with displays. No other powerlink cables will work.

The switches on the back of the speakers should be set to either L or R and the switches on the side of the speakers should be set to Audio.

Power off the whole system. Connect the wires and set the switches. Power on the 9500 and then the speakers.

They should now work as designed.

Hi joeyboygolf ,

Thank you for your help too!

I hadn't even noticed the switch on the side yet, but they were both set to Audio already, so should be ok.

I have had the cables checked by my local B&O dealer, and they are both ok (they are fully wired, and every signal comes through just fine).

I'm going to shut everything off for about ten minutes (the dealer told me it would reset back to factory defaults) and turn them on again. Hopefully it'll help.

I've just switched everything on again, still no sound however...

I took pictures of the beolab when switched on:

 

No matter how high I raise the volume, I can only see one _ in the bottom of the display. Is this the level, or is this some spectrum to show the sound?

When raising the volume in the "Sound" menu they show me the correct level. Everything else works as well.

Could my 9500 be faulty? I didn't run into trouble yet, using line and speakerlink.

Is it okay to use both the powerlink (for the display) and the speakerlink (for audio) at the same time?

Heras

Your output would appear to be muted. Just tried my 8500/lab5000's/powerlink setup and if you press mute on the remote the display matches yours!

Suggest you play with the mute control.

Hi Graham,

Thank you again for your reply. I've tried "un"muting my 9500 both with my remote and the 9500 itself.

Again.... No luck.

It's pretty much driving me crazy. I (think I) know the 9500 works, the guy that sold it to me showed it off to me using PL with 3000's (or 4500's, I don't know) and it worked just fine. The guy that sold me the 5000's used PL as well, and everything worked right away. I've got the cables checked by an B&O dealer, and they are fine. I have collected those beautiful machines myself, extremely carefully.

Strange thing is, any setup I can think of works just great. In every other way but PL. What probably puzzles me the most is that one of the 5000's played for, like, 10 seconds when I connected it, and stopped (shut itself down, is what it sounded like, I think) and never played again.

Can I use both PL and SpeakerLink at the same time? Surely I'd rather use the internal amplifiers of the 5000's, but I'm dying to get the set to work, and getting my walls done :)

Thanks!

I highly suspect the fuses.  A quick look at the circuit schematic shows two 4 amp slow-blow fuses wired into the +/- 45 volt power supply, independent of the lower voltage supply lines used to power the displays.  It's the +/- 45 volt lines that would be powering the main amplifiers.  This means that one of the main amp fuses could blow, while still allowing power to supply the displays.  This would also explain why the speakers were working at first for about 10 seconds.

If one of the fuses did blow, then there's a chance that there may be a short or a fault somewhere that caused it to blow, but I wouldn't be surprised if it was just age.  Remember that you must replace the fuses with slow-blow ones.  When the amplifier first turns on, there is a strong in rush of power for a moment, which can cause fast-acting fuses to blow unnecessarily.

Good luck,
Austin

Oh wait, I forgot you said both speakers don't work, so I guess it's not a fuse.  Well if you're bored you may want to check the fuses anyway.  Sometimes in situations like this I'll check or try things even when I don't think they're responsible for the issue, simply because along the way I sometimes discover the real issue.
