Hi All!

Im looking for a record deck for my Beocenter 9500 and I've been searching for a Beogram 9500 for a while now.  In my search, I happened upon a Beogram 4500 for sale that is very nice, but I am unsure how it work with the Beocenter 9500.  I understand that they are similar decks, but the Beogram 4500 has the pre-amp built in and the Beogram 9500 doesn't?  Im not clear how I would connect the 4500 to the Beocenter...

I would like to have the datalink functions and if I am understanding the differences, the Beogram 4500 would have to be connected to the 9500's AUX port since it has the pre-amp built in?  Which means this would not allow me to access datalink functions between the Beogram and the Beocenter?  Or could I disable the 4500's internal pre-amp?

Any tips or tricks would be appreciated.

I posted a while back about using my BC9500's phono connection as an additional AUX input - which would support your requirement - here is the thread: https://forum.beoworld.org/forums/p/7280/65059.aspx

The 'anti-RIAA' device that I linked to is no longer listed, but you could always put something like this in the signal path to cancel out the second RIAA: https://hagerman-audio-labs.myshopify.com/products/iriaa2-inverse-riaa-filter

But to be honest you would be mucking around with the signal two more times than you need to, which would not be good for sound quality!

I suspect that the easiest option would be to modify the RIAA stage inside the BG4500 - i.e disable it.  If you do so, make sure that the operation is reversible.  There is some further discussion of BG4500 RIAA stage if you search the forum.
