I now have a B&O 8000 Turntable refurbished from Europe. Just got it in.   It has a din plug from the turntable to RCA on the amplifier.  The ground is plugged in to the amplifier.  The applifier is a Rouge High Breed (Has tubes and solid state). From the first record, It has a hiss/hum that does not go away when playing.  As you don't know, the table goes to mute until the needle his the record which is when the hiss/hum begins. 

 

I have taken off and put out back on the cables, I have taken out all electrical plug in's using the same surge suppressor, I have made sure the WiFi in my how is 12 feet away.  I have put the ground in and tood it off. Other turntable used on this set up work perfectly. (Techiniques). 

I am using the 110 to 220 adptor converter since the unit is from Europe. The turntable is on the top of wooden furniture, under is the AMP under that is the surge protector.

The individual that sold it to me, only answer that "I should have used a B&O amplifier. amp and pre-amp".   Good to know after you have the turntable. I simple can't belief that last statement. 

 

My choices are to give UP, box up this turntable and put it in the attic somewhere.  Eat the financial loss and buy a much simpler unit.

 

Can you help me.

Gary

Hi, This is a common problem.  I have used Beogram 400x and 800x turntables for years with both B&O receivers and non-B&O receivers. So the person that told you that you should have used a B&O amp is full of you know what.

For a non-B&O amp the DIN to RCA jack adapter should have a separate ground wire that connects the Beogram chassis ground to the amplifier chassis ground (usually a lug on the back of the amp). Some Beogram 4002 units came fitted with RCA jacks and the ground wire already. 

The other things you tried - surge suppressor, WiFi, etc, should have no effect on the hum problem. The hum is due to the grounding in the phono signal from the Beogram to the amp. 

If you have the grounding wire connected and still have the hum then there is probably a problem with the cable. If the cable is not the problem then I would suspect the DIN output plug module in the Beogram where the muting relay is located. 

I would contact Steve and Sounds Heavenly and have him provide you with a Beogram cable to a non-B&O amp. He can take care of the grounding in the cable.

Hi Gary,

Welcome to Beoworld!  Yes, sonavor is correct (thanks for the referral, by the way!), this is a common issue due to the dual grounding connections required for these turntables.

Using this cable (external ground wire option) between the Beogram and the pre-amp should resolve the issue:-

Any questions, please feel free to ask.

Kind regards, Steve.

Sonovor:

 

WOW, you are so kind to help me and YES Steve did contact me directly.  I just finished sending him a detailed message on my situation.  I am waiting for his recommendation.  Seems to easy and simple.  But that is what life's little problems usually are.  

I think, I will go with what ever Steve says, the special B&O 8000 DIN to RCA with a ground cable will be all it takes.  I hope so anyway.  

 

Sonovor, that you so much for reaching out to me.
