Hello fellow Beophiles,

 

I am having a problem getting a Beogram turntable playing properly in my system.  

I have a Beocenter 9500 in one room

and a BeoSystem 6500 (no turntable) in another

I have a Beogram RX and recently acquired a Beogram 5500 and  I have MMC2 cartridge/stylus

1.) Am I correct that the Beogram 5500 should work fine as is with either of my systems because it has a factory DIN connection and the Beogram RX2  will require a preamp?  

2.) When playing a record on the 5500 with the MC2  in either system I get a muffled, flat, or clipped sound.  I am thinking that maybe there is something wrong with the cartridge or stylus. 

Any ideas or assistance would be appreciated.

Hi.

Neither of those beograms have a built in preamp. The DIN connector isn't an Indicator.

The Beomaster 6500 doesn't have a built in preamp either.

In order to use either turntable on the 6500 system you will require an external preamp.

The 9500 on the other hand does have a built in preamp so you should just be able to plug in the turntable and be good to go.

As for the muffled sound... Ensure that the tracking force is set correctly (1.2g) and check that the stylus is clean under a magnifying glass.

Lee - I too am having problems with my 5500 turntable linked with the full 5500 system.  I am getting a real muffled and distorted sound through my Penta speakers.  It has started to happen recently prior to that it was playing wonderfully.  I changed the MMC4 to another one and still I am getting the problem.  I have moved the styli weight up and down but still no use, in fact the lighter the styli weight the worse the sound.  Prior to this I was getting a brilliant sound.  Nothing wrong with the pre-amp in the 5500 tuner/amp, even changed the 5500 tuner/amp to a spare one I have and still the same.  Would the turntable have a problem?

 

Thanks David

Very strange....

Could you try the cartridges on a different deck?

There's not much electronically in the signal path on the Beogram 5500. Maybe it's a problem with the muting relay...

Try playing a record, when you hear the record through the speakers raise the tonearm. Repeat this process of play, pause a dozen or so times and see if that fixes it.

The MMC4 wants a tracking force of 1.4g to sound it's best.
