Hi All,

I recently picked up some 6500 and 5500 gear to go along with my old RX2 turntable and along with it was a tan box to plug my turntable in to make it compatible with the 6500 receiver... but it plays super lower and i'm guessing its a pre-amp of sorts and needs a power source... it has a female connection for "IR" and "DC".  I don't know what IR is for but i'm guessing DC is for a power source. Pics attached.

Can anyone confirm that, and if so is any 12v plug ok (I'm in the US).

Thanks!

I'm assuming that there is no data listed under the preamp? Looks a little sketchy.

Lol - funny, totally sketchy... 

there's no name on it but i just found a partially rubber off number on the bottom... P150X5 - which i just googled, and its a basic plastic enclosure - i opened it and there are some electronics in there and it doesn't work - its just that the volume in super low.  

My system also came with some other boxes that have the B&O name on it - looks like speaker connectors - see attached.
