Why do I need a special cable?
You don’t!
the Beosystem 3 has more powerlink sockets and if I use for every Beolab an extra socket (one for left, the other one for right…..) this would not work?
Correct, you’re right this would work.
We have this discussed here too …

4 March 2023 at 09:12 #44304Hello!
is ist possibile to put 5 Beolab 7.4 as an surround system?
does it make sense?
i have them from other installations and i thought if this would sound good?
the TV is a Beovison 7/55
hope to read some „inputs“ from you 🙂
kind regards, beos6
4 March 2023 at 10:57 #44305Why not? It is a cheap solution for great sound.
I do that only with 2 BL7.4 for stereo sound and it is so much powerfull when you look movies.
You need a special powerlink cable that to do the stereo signal splitted in left and right channel.
A german company do that for me. In UK is our sponsor Steve from Sound Heavenly the best address.

I always ordered my cables from steve but now the tax for goods from England is to high
can you tell me the adress from the german dealer?
kind regards from Austria, Beos6

Why? 5PL connections on the BV7 PL connected to 5 Beolab 7.4. Then program to right output to the correct 7.4.
You can even chain two BL7.4 to each other!4 March 2023 at 14:03 #44308Why do I need a special cable?

4 March 2023 at 14:27 #44309Have you try that out? I have it and it dont works with my BVE. BL 7.4 is only a mono speaker and not a typical stereo speaker from B&O as the other ones do you know.
But ok, I am not a technican and I am very happy with the splitter when the helicopter flight from the left side to the right side in movies.
You can try it out and make your own experience.
Contact here
or over ebay here
maybe Steve can answer here too about the mono problem with the BL7.4
Steve dont send outside UK for this moment 🙁
4 March 2023 at 14:50 #44310Hi beos6, not a bad thought! Powered speakers with proprietary acoustic lens technology in a casted aluminium cabinet, sometimes for 50 euros. Hard to beat, they were not cheap when new, like 2500. You might need some space for the BV7s and stands that come with them though :-). And they tend to be a bit sticky.
What was your thought how to place them (stands)?

4 March 2023 at 15:01 #44311Thank you for all replies.
I will make a wall mount in front and maybe stands for surround.
4 March 2023 at 16:09 #44312this is a great idea…!! never thought of this.. If we use just 1 Beolab 7.4 for center.. we only send Left OR Right…correct? We dont send both signals (L R) to this speaker. I ask because..i have a 7.4 that we make the RCA cable to powerlink and 12v trigger. We send BOTH left and right..but the speaker sounds very loud..more than the other speakers..i think we send double signal too much.

Interesting, but….
there is a difference. If you connect them to a Beosound the PL will always have the right and left channel.
if you PL connect the speaker to a BV7 and instruct to play for example “front right” to this PL connection then it only will play this channel.That said, with the quoted post in mind, you should not chain the speakers but feed/connect them separately.
5 March 2023 at 09:06 #44315Could be …. but I have my further misgivings with the mono speaker BL7.4
I dont try that out because i had only 2 PL DIN/DIN cable and a DIN-DIN/RJ45 splitter from the BL7.4 to the BVE
BUT why is that splitter working with every other BL speaker and only NOT with the BL7.4?
Now is it as it is in my setup with my left/right channel splitter and I am happy with this.
7 March 2023 at 16:25 #44316Hi Sir… so.. you are just sending 1 channel to the BL 7-4? (L or R) correct? ive been having issues also sending both channels to the same speaker..
7 March 2023 at 18:04 #44317hi,
how you can see in my setup that I have two BL7.4. Left and right.
I splitted the stereo powerlink signal from my BVE with a special splitter cable for the left and the right side.
You cant hear a stereo signal from only one BL7.4 speaker. The BL7.4 was to build as a center speaker for BV7
In my setup that works pretty good but the opinion are divided here.
It is up to you to try something out.
8 March 2023 at 12:24 #44318The BL7-4 hardwires internally the left and right channel. So, in a stereo setup you need to split the cable into a dedicated left or right channel.
If you use a powerlink socket on for instance a BS3 you will notice that 2 channels will give sound on the BL7-4 on the used socket.

(BS3 = Beosystem 3?)
This depends on the set-up of the channels in the BS3.
PL connect every BL7.4 with one PL cable. Setup one PL socked (= one BL7.4) to reproduce 1 channel (f.e. Surround Left), et voila.
But on a Beosound you can’t choose, so you’re right then one will hear both channnels.
