The two missing prongs are for datalink remote control. You may well need these but I couldnt tell you if the deck will operate via remote with a 2500 ststem. I am sure someone will come on that does know the answer to that part of your question.</p><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/266236.aspxWed, 24 Mar 2010 14:03:00 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:266236andyrowsell0https://archivedforum.beoworld.org:443/forums/thread/266236.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=266236<p>i wonder if you can help. i have just bought a beogram 3300 and noticed that there only seems to be 5 prongs in the din plug but it looks like there are 2 missing.&nbsp; I have plugged it into my Beosystem 2500 (attached to BeoLab 4500 speakers ) and there is no sound coming out. Can you advise me if i need a separate pre amp as I don&#39;t understand whats going on. Really appreciate your help.</p> <p>&nbsp;</p> <p>Andy</p><div style="clear:both;"></div>
