Hello Henrik thanks for your reply,

On my beomaster 5500 all I can hear is speaker 1 output, both the left and right channels on speaker 1 sound fine, speaker 2 however does not output any audio at all.

I'm sorry this seems so complicated to me, these are my first Bang & Olufsen receivers I have owned and the whole concept of how everything operates with the master control panel and receiver is all new to me.

Would there be something wrong with my receiver?

How have you got the second set of speakers attached ?

In general B&O's design is not for just a second set of speakers but rather a series of link rooms.

Look here for some background data: 

hello elephant,

I have the beomaster 5500 hooked up to 4 jamo J-103 speakers, both pair are connected directly into the receivers Speaker 1 and Speaker 2 left & right outputs. Only speaker one works on the left and right channel.

I do have a second Beomaster 5500 and both speaker 1 and Speaker 2 work just fine with the same 4 speakers hooked up to the speaker 1 and speaker 2 outputs.

 So I have no idea what the deal is :\

That is a puzzle.

Did you use the same wiring for testing both BM 5500?  Because I thought there had to be an extra signal to activate the Speaker 2 ports ... and that signal usually comes from the MCL box ... but I could be wrong.

I have an older BM 5000 and its older MCL-82 connections which seem to work that way.

Do you have tools that can test the electrical signals that are on the Speaker 2 plugs ... both at the BM 5500s and at the ends of the speaker cables ?

In a 5500, there is nothing between the amplifier outputs and the #2 sockets. #1 outputs go through the muting relay, and they can be switched on & off.

So it can't be a configuration or usage issue if the same speakers with the same cables and same plugs work in the same sockets in another Beomaster. There must be something physically wrong with the #2 sockets - possibly solderings broken off due to somebody yanking on the cables in the past. Or somebody has used rusty 2" nails or coat hangers to hook up the speakers, and the sockets won't make contact with proper plugs any more.

I think that maybe the OP has simply confused the speaker 1/2 sockets and it is infact the speaker 1 sockets that are not working?

OP try excersising mute a few times and disconnect the active speakers to see if anything can be heard. If not maybe a new relay is in order?

Hello everyone,

Sorry for the delay in my response. I am pretty sure I had it hooked up correctly, but then again the way the print is on the BM5500 for the outputs and inputs can get confusing.

Speaker 1 is the top speaker outputs with speaker 2 being the bottom right?

I have tried the mute function as suggested, with all 4 hooked up, it did not make a difference. I am technically able, but I wanted to make sure it was not something I was doing before I have to start working on it. Seeing as I can fully operate the other beomaster 5500 without issue I am tending to beleive that this one has an issue.

I will check later today and see if the solder contacts have become damaged, as well as the connections themselves. I can see how some people will jam anything into the outputs to save themselves a buck.

Thank you all for your help so far :) Great to know theres a place to go for these receivers. Neat little units that have nice sound quality.

One other thing, I also have a Beomaster 6500 that has a fried ouput channel. I am wondering if the power output rating of the beomaster 6500 is 110 watts per channel vs 50 watts per channel for the Beomaster 5500? I am going by what I have seen searching google, but I would expect people on this forum to know a bit better than a search engine

Jeremy :)

Yes, they are confusing especially if you look from the above... looking at the drawing in the setup manual without a live specimen, I still can't say which ones are on the top! 😂 In any case, #1 are beside the grounding screw (and have 4 pin sockets), #2 beside the DIN socket for an external IR receiver or whatever it is for. #1 should follow the muting function, #2 stay on all the time.

The circuitry differs very little between them. I believe the higher output of the 6500 (and 7000) is all due to a different way of specifying the power or which line you look at in the spec sheet - actually, the 5500 is also specified as 2x110W/8Ω measured with the IEC norm (and 2x50W IHF, as you say). Here's more on that if you really want to confuse yourself:
