Hi there
Looking for some help in diagnosing a problem.
Have an Arcam AVR350 amp with line out leads into Beolab 6000 speakers. Occasionally the speakers used to give off a humming noise that got progressively louder, simple touch of the RCA plugs into the back of the amp sorted this. Recently its got more often and now seems permanent.
Have tried different leads, unplugged items from the amp, only cure is when any RCA plug and lead is not connected to the speakers and that's also with the other end free. So seems like the speakers? But both of them, that's unusual right?
Any help or peoples experience with similar faults would be appreciated.
Cheers
Harvey

welcome to beoworld
love the 6000s -- so iconic
are you in the UK, what power supply are we talking about, is it earthed ?
is the amp and the speakers on the same circuit ?
are you up to wiring your own leads (see biotech site) or perhaps you should contact Steve and "Sounds Heavenly" (see his ad at the bottom of the beoworld page)

Isn't this your answer? Something like a bad soldering in your Arcam?
You could try a different source to isolate the problem. Connect a mp3-player or your smartphone to your bl6000. You need a cable minijack <> RCA to connect.
Ok, thanks for that, had thought about connecting my Ipod as suggested, but I have tried a different lead into the speaker without the other end attached and the humming noise is prominent when doing this I excluded the Arcam as the culprit.
Hello Keith
Hello Harvey,
Yes, this does seem strange that both speakers are affected. It may be an issue with a poor connection, so it is always worth checking that all plugs are fitted securely. Some amplifiers and receivers can cause noise to be induced into Beolab speakers when they are in standby mode, due to their pre-amp output circuitry, but the Arcam certainly shouldn't be doing this when it is switched on.
Whilst I don't think its a cable fault from your description, I'm always happy to test the cables for you at any time so that they can be ruled out, or I can post you a free iPod cable on loan to allow you to test the speakers with a different source if you prefer.
If you need any further help, please feel free to ask. Please let me know what you discover.....
Kind regards, Steve.
Steve.

Thank you for the reply:

240 v, not earthed, standard two pin plug power into the beolab's
Have swapped power supply so the speakers are on a different socket in the house (pretty sure the sockets are on a different fuse but not 100% confirmed)
Leads - These are from Steve
Steve has mentioned the speakers might have loose internal RCA socket wiring, but seems a bit strange on both speakers, so before I take them down to a repair agent in Kingston was hoping to see if there was something wrong with my set up or common causes.
Many thanks

Steve also suggested trying a source other than the Arcam - have you been able to do that ?
Thanks for that
Going to see if I have an Ipod lead that I can sue with an RCA plug on the end
