Hi,

I tested a mint condition BeoSound 9000 MKIII this afternoon and noticed an audible buzz coming from the speakers whenever I adjusted the volume up or down with the panel or with the beo4 remote. I changed speakers and speaker wires thinking that was the issue but same thing. So now I’m thinking it’s something internal. However, when I used the headphone port there was no buzz when adjusting the volume. Is this buzzing normal? What do you think is causing this? Any insight is appreciated.

 

Thanks

We had this once with BV11& BL6000, via TX1&RX1 replaced the link cables for screened RJ45 and problem solved.

Do you think the volume buzzing issue is on board or just some bad power link cables?

I will look into this, thanks. Seller claims the buzzing is normal behavior. This can’t be true right?

You are listening to the signature sound of the unterminated data transmission on the Powerlink cable.

It has been around since the dawn of the LX2800 TV / Beosystem 5500

There are two options

Get Beolabs with the green signature display or get the MKIII Powerlink cable. (ask Steve)

Either way,- your BS9000 is perfectly fine, enjoy!

Hi,

Yes, good cables should resolve this, the noise that you are hearing is the Datalink pulses from pin 6 of the Powerlink cable getting onto the audio channels (pins 2, 3 and 5).  The noise is certainly not normal!

Please feel free to get in touch via my sponsor link below if you need any help with cabling and I will be pleased to assist.

Kind regards, Steve.

Bang and Olufsen produce exceptional quality in music.  Any back ground hum is not

normal.  I have had a similar problem with jack from my iMac Computer straight to beolab 11/Beloab 6000 X2.  Very annoying hum.  All Mk 2 cables,   Does not change with the volume.  Tried a ground loop thingy:  no better.  Now, if I use the beocentre 2 "Angel wings" and the connections box,  which AUX in going to the iMac, and voila no hum with the Beocentre controlling things.
