Hi guys,

 

I was finally able to move back into our apartment yesterday! Very happy about that, been "homeless" since august first!

 

Anyway, connected all bits last night, and I'm having a problem with my beolab 5's...

 

The system now consists of BV10, BS9000 and Beolab 5.

It's connected as follows:

BV10 -> BS9000 with ML

BV10 -> Beolab5 with Powerlink

BS9000 -> Beolab5 with digital coaxial

 

The problem I'm having is that the Beolab 5's seem not to get/ignore the digital signal... It's a long time since I last pulled the digital cable out from the speakers while playing music, but as I remembered there was a short pause, now I can't hear anything.

 

The reason why I got into testing this is that I first had them connected like this:

BV10 -> BS9000 with ML

BV10 -> Beolab5 with Powerlink

Mac Mini -> Beolab5 with digital coaxial

And couldn't get any sound from the Mac Mini.

 

Now is my problem as simple as a cable fault? (I don't have a meter, but can buy one) I have switched over the digital cables, but it did not help, hard to believe both to be broken, but then again I can imagine the Beolab 5's will only work if both digital bales (loop) are properly fastened.

 

What should the cable values be if I go out and buy a meter?

I think you should check your option settings and what you have set up as audiomaster. For the s/pdif to be recognized by the speakers when you press CD, i think you need to check the config btw bs9000 and bv10.

Others here will be more knowledgeable than me as to specifics.

Digital in/out on BLb interchanged by mistake ?

"Power reset" done ?

After connecting and option programming of all components
disconnecting of all units from power for approx 2 minutes is
always recommended.

Hi,

 

Thanks for your replies.

The options should be, TV -2, Bs9000 -0.

But should I set these manually, or?

Did the power reset, nothing changed, also checked manually (with Beolink 7000) that BS9000 is set to 0 and Beovision 10 is set to 2...

 

Nothing changed...

 

Is my problem related to me having the speakers connected to the TV? I had them connected to the TV before also, but I don't think I ever had them connected to the TV while using a mac mini as transporter...

are digital cables connecting BSd 9000 <> BLb5 <> BLb5 working when selecting CD ?

mac mini connected to TV :

AV input #? 
configured as ? e.g. "V.Mem", ...
connected by HDMI ? 
or VGA or Component + SPDIF ?

OK, did what I said, and it works now....

 

So having the TV in option 2, and BS9000 in option 0 with powerlinks from TV to Beolab 5's seems to block the digital input...

So what do I do now......? Will the speakers work with surround sound left/right via ML to the BS9000? I suspect not... 

Damit... Will my only option now, be A.aux and a good DA converter...? 

 

Or is there a way to open the above described problem, making the Beolab 5's accept spdif even if connected to the BV10?

I don't have the Mac Mini connected to the TV... Only connected to a separate Cinema Display in another room, only connection to the Speakers via spdif coaxial cable.

 

So you think connecting the Mac mini via SPDIF to the TV instead of the beolab 5's would make it work, by making the macmini ie V.mem?

If you had everything connected as described, then you ought to be fine.  When the BeoLab 5's 'see' an audio source 'displayed' on the PL cable, they automatically check the S/P-DIF input first, and if a signal is present, they lock onto it and stay.  This is one major reason that you must use fully-mounted PL cables in these set-ups.  The data signal must be present.  

Since the mini is playing when it is connected to the 5's instead of the 9000, we can expect that the cables are OK.  Try this...reconnect all of the B&O gear as it should be (listed in the OP) play the CD and try to adjust bass or treble...if there is an audible change, then you do have a problem of some sort.  No change, no problem!
