This is difficult one to diagnose so far. I'm guessing that you don't have another Beomaster to check the Beogram with? And that you do not get a humming from the radio? And that there is humming from the record player before the arm is lowered, ie as soon as the gram is "live"? You are correct that the DIN plug from the gram should carry an earth signal already. Peter is almost certainly correct that the humming is caused by a bad earth - somewhere.

There are two gram sockets on your Beomaster - number one is for grams that already have a pre-amp and number two is for grams that do not. I think I'm right to say your Beogram 8002 does not have a pre-amp built in and that you should be using socket two on the Beomaster.

You need to hunt down where the problem is - try using a fly lead from the centre pin of a spare socket on the Beomaster to a metal part on the Beogram chassis. If that cuts the humming then that will at least confirm an earth problem. A multimeter set to measure resistance will help narrow the problem down to either the record deck or the amplifier. Chances are most likely that it is the earth connection to the centre pin on the DIN plug of the gram.

Good luck, Steve

PLEASE Is there anybody who want to help me with this problem. I thought if I had a normal 5 pin cable this should be ok?Do I have to ground it separatly from this cable(extra).

Is the ground problem in the BM1000 or the beogram?

Which record player are you using? It sounds like an earth problem - there should be an earth from the chassis to the casing of the DIN plug.

The two keys, you describe are filters.
High-cut and low-cut originally there to remove high frequency "needle-noise" and rumble respectively though they will actually work on any source you play.
The symbols are indicating two sine waves, where the upper respectively the lower are crossed out.

I have recently bought a beomaster 1000. I am wondering about two things about this

The first since I don`t have a user guide. The BM has two piano -function keys between speaker II and the mono key , which have a sign like ~ (two of these in parallel). Probably a stupid question, but anyway, What are their function?

The second is when I play a record player connected in I get humming sound in the speakers. Do anybody have heard of this problem and is it a sollution to it?
