Hi

Its a Beolab 2, and the TV is an Eclipse 65.  It is listed twice in all the sound settings - speaker groups, speaker distance, calibration etc.  I can set each mention independently

@Lawrence:

FYI, the BeoSystem 3 menu logic behaves differently. So, everything I said above doesn't apply to you. :-)

Cheers

Thank you so. much, Geoff, for explaining that so succinctly. All is clear now

Geoff:

How do the menu settings work with the BeoSystem 4? I've always been frustrated that the subwoofer and also the center channel each use 2 channels -- using up available BeoLab connections when it would be nice for them to each use just one connection.

Hi Beojeff,

The short answer is that this is a hardware issue - not a software problem.

We have to distinguish between the menus / BeoSystem 4 behaviour and the loudspeakers to which it's connected.

WRT the Software

There's nothing in the logic controlling the menus that stops you from having (for example) a BeoLab 2 and a BeoLab 17 on the same Powerlink cable. (I was a little in doubt - so I just set up my BeoVision 11 (which is the same as a BS4) to do exactly this... in the menus...) Similarly, I could have two BeoLab 2's connected via a single Powerlink cable, if I split the signals correctly... (read on!)

WRT the Hardware

If you have a BeoLab2, BeoLab 7-4, or BeoLab 10 connected via Powerlink, then all three of these loudspeakers will sum both incoming audio channels on the Powerlink. This is where the "problem" starts.

If (for example) you want two subwoofers connected to the same Powerlink output on the BS4, and you use a "normal" Powerlink splitter, then you will be sending both Left and Right channels to both subwoofers. This is because the "normal" Powerlink splitter sends both channels to both Powerlink terminations (because normally, you can use the L/R switch on the loudspeaker to "tell" it which channel to play.

HOWEVER, the was a "special" Powerlink splitter that was available in the DIN days for splitting to two subwoofers. It split the audio channels so that the left channel went to one termination and the right channel went to the other. I believe that the other channels were unconnected - so if you connected (for example) a BeoLab 8000 to the Left side of the splitter and set the 8000's switch to Right, you would get no sound...

The problem was that the "normal" splitter and the "special" splitter look identical from the outside. So, if you weren't paying close attention to the part number (say, if you were stocking them at a dealer, for example), you might just throw them all together into the same box on the shelf... This didn't happen often - probably because the "special" splitters were a bit rare...

So, if you use a "special" splitter - or if you manually cut one of the two audio channels on a Powerlink cable to make it either a Left-only or a Right-only cable, then you could connect (for example) a BeoLab 2 and a BeoLab 17 via a splitter on the same Powerlink - and the menus will allow this. (Admittedly, this is not easy to do with the RJ45 cables - but BeoLab 2, 7-4, and 10 are all DIN inputs, so it's easier to get inside the DIN connector and cut the connections to the pins in there.)

Note that a BeoLab 19 has the "L / R / L+R" switch, so you don't need the "special" Powerlink splitter for this.

Hope this answers your questions
