Hi Zhenia, and welcome!

From what I know the BeoMaster and the A/V7000 need to be connected like this:

- an Audio Aux Link connection between the TV/Aux socket of the BeoMaster and the A-Aux socket of the A/V7000 (this is for the control signals), plus

- a PowerLink connection between one of the Powerlink sockets on the BeoMaster and the PL-Input socket on the A/V7000 (this is for the audio signals)

Then the BeoMaster should be set to Option 0 and the A/V7000 to Option 2. This will make sure only the A/V7000 receives the IR commands and controls the BeoMaster.

When you do not have these cables yet, I recommend to order them from Steve (sponsor of the site), he will get you the right cables for sure.

Nice and classic kit you have! I myself have a BeoMaster 6500 (almost the same) and for a while played with the idea to get an A/V7000 from the USA (they were not sold here in Europe I believe). I went a bit less classic with a BeoSystem 3, but connected with the 6500 🙂. 

Hope this helps!

Thank you very much for your suggestion!

I will try it as soon as I get home.

I cant hardly wait to play with it.

B&O for Life...

I was able to set BM 7000 to sound option 0 successfully 

Trying to set option 2 on A/V 7000 it seems more challenging 

there is no visual confirmation on display as there is on BM 7000

how ever I do hear relay clicking inside thus assuming it changed

connected cables as you suggested 

7 pin DIN cable for Aux/A > Aux/TV

8 pin DIN cable for Power Link 1 > Power Link In

Now System does not respond to remote what’s so ever

attempted to power it on manually only MB 7000 responds

A/V 7000 does not.

assuming sound option isn’t set properly on A/V 7000

please correct me if I’m wrong ...

One unit at a time in stand-by

I press

Sound, 0, Store on BM 7000 and 

Sound, 2, Store on A/V 7000

what else should I check for

I thank you for your time and input 

Hi, good that you have the cables connected. The option setting is done with the remote control. Which one do you have?

here you can see how that works with Beo4 and BeoLink 1000 https://www.beoworld.org/beotech/mlsetups.htm

(I reckon you will need to be sure to cover off the IR sensor of the other device when doing so)

what could also be tried

press 'sound 0 store' to set the beomaster to option 0

and

press 'picture 2 store' to set the A/V7000 to option 2

Thank you for prompt response

I have Master link 1000

I will attempt that  as soon as I get home

Thanks again for your advice. 
I found disconnected wires on one of my older 7 pin din cable

Replaced it with a new one.

system works perfectly.

Sweet victory at last! Glad it works now and thanks for letting know.

Do you actually have the manuals of all yor components? I see you are a gold member so you can get them here at the site.

Enjoy!
