Hi all,

I have a Beogram 5500 that does produce sound via my Beomaster 6500. The controls work normally but there is no sound from the speakers -- I can faintly hear the record but something is not working correctly as there is no sound coming through the speakers. Everything else connected to the Beomaster works normally.

I know the Beogram is working OK, I have plugged it into a separate Beomaster 5500 that I have and it works normally. It is not the cartridge as I have swapped with different MMCs that I have in backstock.

Is there something unique about the Beogram 5500 that doesn't allow it to play with the Beomaster 6500?

The system is as follows: Beomaster 6500, Beocord 5500, Beogram CD 6500, Beogram 5500 (MMC1), CMM10, Pentas MK3, Attyca 1

Thanks for any help,

--Jonathan
 

 

Hello Jonathan,

The good news is your equipment isn't broken. The bad news is you don't have a RIAA in you particular setup. The RIAA is  a pre-amplifier you'll need in order to get sound out of the recordplayer. The RIAA is built in the Beomaster 5500 and the Beogram 5500 will work fine with it. The RIAA wasn't built into the Beomaster 6500, but in the Beogram 6500 instead. When you hook up a Beogram 5500 with a Beomaster 6500 than there's no RIAA, and therefore you don't hear it as loud as you should. I believe you can get a seperate RIAA, but I'm not sure.

You can get an external RIAA, but it will most likely have Phono/RCA connections.

Thanks for the reply -- I suspected something along these lines but wasn't sure of the details. I'll be keeping an eye out for a white 6500 or 7000 to match the rest of the system.

how is your search progressing, I might be willing to buy your 5500, as I have Beomaster 5500 in my study :-)

 

 

Hi,

I have just realised this sort of "contradiction".

In the technical specs of BM6500 (as you can see in the products section) it seems that RIAA pre amplifier is actually built in.

My question is: belonging the BG6500 to the "new" beograms generation with built in RIAA pre (like 4500, 3500...), how could I connect a BG6500 (!!!!) to a BM6500 (they were build to match!!!) if both apparently have the RIAA preamplifier? Did I miss something?

Thanks a lot for your answers...

Whatever the products section may say, I can assure you that the standard BM6500 does not have RIAA pre-amp built in.

The products section refers to the RIAA accessory that was available at the time but which has not been available for some years.

Thanks for your answer Graham.

Now my problem is: is the BM6500 riaa preamplifier switchable? Alternatively, is it possible to take it off without soldering operations etc (e.g. is it a removable board in the BM6500?) and take the BM6500 back to its original condition?

The reason:

I have a BS6500 (BM, CD, BC, Penta) without the record player and I'd like to add a BG6500. Fortunately, before buying it, yesterday I tried to connect my BG3500 (technically identical to the 6500) to the phono socket of the beomaster. With great surprise, I realised it can only be connected to the aux or tape2 socket; otherwise, using the phono socket, the riaa-amplified signal (coming from the record player) seems to be amplified again in the BM6500 before reaching my speakers.

Is there an easy way to sort this out?

I believe that the fitting RIAA board involved a small amount of soldering and I dare say some links have been cut.

If you prefer, you could disable the RIAA in the deck. I've never actually done this but I have had to reverse the procedure on a BG4500 deck that had been disabled.

Of course, you also probably have to reverse the datalink connection in the DIN plug fitted to the deck.

At the end of the day, you may be better off getting the RIAA remove from the amplifier by your dealer/service center. It should not cost too much.

Hello Graham,

what do you mean for "reversing the datalink connection"? Are there two types of datalink connections? Is there any difference in the datalink for a RIAA and a non-RIAA record player? I thought there was just one single datalink cable.

RIAA decks have datalink on pin 7 of the DIN plug and non RIAA on pin 6!

Thanks for your precious infos, Graham. In the Master Link Guide there is just one datalink plug with datalink on pin 7. I wasn't aware of the existence of the other type.

At the end of the day, the easier solution would be to buy a Beogram 5500 (which should be a non RIAA deck if I am not wrong) and plug it into my RIAA-BM6500; in that way I would have a correct amplification using the phono socket of the BM6500 and also a correct datalink transmission without having to get the items serviced (i.e. I could control the record player from any remote - MCP6500, BL1000 etc...); am I right?

 

mauro

Quite correct. The Beogram 5500 should be plug in compatible.
