Beosystem 3 phantom center

16 replies

 

Hi Geoff

 

Thanks alot for your suggestions. If I setup my BL5s as left centre, and right center I can't save and exit the menu. I have to assign left front and right front before save and I can't give the same speaker more than one role.

 

I also tried connecting my BL5s to the dedicated center powerlink connection where my 7.4 is normally connected. Then in the speaker roles menu I can setup that I have a pair of BL5s as center. But still I cannot save and exit without choosing another set of speakers as fronts.

 

My service menu ( menu + menu + 0 + 0 + Go ( for reference )) states the following key info:

 

AP SW06.11a

IOP SW23.00a

Type no 9383

Serial no. 2068xxxx

Option setting 2

 

An earlier thread exists here at Beoworld from around the time my TV left Struer, discussing BS3, phantom center and several people refering to ”the misssing phantom option”. It's an interesting read:

Now I'm interested to know if and how a phantom is possible today or I'd have to go with an external processor as seems to be the suggestion in the old thread.

Just to be sure... When you did the Left Centre & Right Centre attempt, your BL5's were on PowerLink connector 1 (the one for the Centre channel), right?

I made two attempts. 1) With the BL5s in a normal powerlink connector 2) With the BL5 to the special center connector.

Ad 1) I can assign the BL5s to left center, right center but I have to also assign another set of speakers to front left and front right. Otherwise I can't press Go to Save and Exit.

Ad 2) When connected to the special center powerlink connector my BL5s will play the center channel but again I have to assign speakers to front and left in order to save and exit.

Since my last post I did two more discoveries. Though they add to my understanding of the system they do not provide a solution.

1) I think I know now where you want me to go. Because it's true that I can assign my BL5 as center left and center right. If I assign nothing else than that, I can save and exit. My Daughter is sleeping next door so I can't really test and hear what is delivered, but I would think in that case it is the complete stereo signal.

The problem is that I can't assign my BL8000 as surround speakers without also specifying front speakers. This is where it won't allow me to save if I try.

2) The other discovery I did is a way to cheat the system. If I setup all channels in the speaker roles menu and then completely remove a set of speakers from the connections menu, then I actually have a setup where for example no front speakers are assigned. The problem is then, that the audio from these channels is completely missing. So sadly still no luck...

After some hours of tinkering with the sound setup I think I'm ready to conclude. The speaker role setup menu have have som built in rules, that prevent me from assigning some roles without also assigning other roles. My problem is this rule

1) you cannot assign surround speakers without assigning front left and front right.

There are other rules of which at least some make very good sense

2) You cannot assign back speakers without assigning surround speakers.

3) another rule is that you cannot assign front right and front left without assigning either center or center left and center right.

4) then there are the rule that say you can't assign for example a left speak without also assigning an equal right.

If you break one of these rules nothing happens when you press Go to save and exit. I recall having seen other users of beoworld asking questions about this, wondering why nothing happens.

So my problem is that I can't assign surround speakers even when center left and center right are assigned because I have no front speaker roles assigned and therefor rule oneis not met.

If there is a way around this of course I'd be very pleased. If not the question is if and how an upgrade of my beosystem 3 can cure this problem or I'd have to go for an external processor.

Hi,

I'll start this posting by exempting myself from the Truth (once again), since I spend my days working on the next-generation B&O gear instead of the stuff that's currently in the stores.... however, here's what I've found...

I wouldn't be surprised if the rules that you "reverse-engineered" are probably exactly right for your HW/SW configuration. They have been changing slightly between SW versions, so I don't know about version 6.11.

I've tried duplicating your setup on two different BS3's with two different SW versions here (10.x and 11.x) and I have found the same problem as you. I can't have a centre-less surround setup and use Speaker Mode 5. This is true even if I have an AST-capable SW (with AST ON globally, but disabled for the Listening Preset I'm working on).

Since I can't make it happen with newer gear than yours, I would say that, if you do decide to go for the upgrade - make sure that it'll work before you leave the store... The dealers know far more about the existing gear than I do - so there might be a neat trick that I'm missing to make this work... In other words, for this issue, trust your dealer more than you trust me - but I can't make it work.

I'll dig around on the weekend to see if there's a 3rd-party solution for your problem. I'll assume that you want to buy a pre-made box and that you don't want to get out a soldering iron and start building circuits...
