CapZark Posted April 9, 2010 Share Posted April 9, 2010 Anyone ever seen an amp with connectors like this on the back? It's a Yamaha P2250C. I was hoping to use it for 2 channel audio, but there are no RCAs, etc. Maybe it's a Home Theater amp? Does anyone have any suggestions on how I might run this thing with a pre-amp signal and then on to the speaks or am I out of luck? Quote Link to comment Share on other sites More sharing options...
wsd Posted April 9, 2010 Share Posted April 9, 2010 Here is a link to the owners manual - it may help. http://www2.yamaha.co.jp/manual/pdf/pa/english/amp/P2250E.pdf Regards, Shawn Quote Link to comment Share on other sites More sharing options...
kouack Posted April 9, 2010 Share Posted April 9, 2010 Use the XLR input or the stribarrier, you can buy a RCA cable that terminate with a XLR, just keep in mind you can have ground loop noise but rare. Those are pro amplifier and XLR is the Standard with 1/4 TRS plug. http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10244&cs_id=1024404&p_id=4777&seq=1&format=2 Quote Link to comment Share on other sites More sharing options...
CapZark Posted April 9, 2010 Author Share Posted April 9, 2010 Thanks, I found that too before I came here, but oddly enough the pictures in the manual don't match the back of this thing at all. The P2250 in the manaul has Phono jacks. The one I have is a P2250C? I can figure out what the big round inputs are? I guess I could use the XLR inputs, but they are 3 pin and the pre-outs on my existing reciever are RCAs (2 pin). I don;t want to blow something up especially my reciever or La Scalas.

kouack Posted April 9, 2010 Share Posted April 9, 2010 The big round thing are usually for optional Crossover, the cable above is what you need, i do have 6 pro-amp connected to my AVR with that type of cable. Quote Link to comment Share on other sites More sharing options...

Don Richard Posted April 9, 2010 Share Posted April 9, 2010 Are the octal sockets for plugging transformers into, perhaps? Quote Link to comment Share on other sites More sharing options...
Islander Posted April 9, 2010 Share Posted April 9, 2010 Who snips off the cables like that, other than someone who's leaving the premises very quickly and has no time to waste? Just wondering... I've noticed things like that in pawnshops on occasion. Quote Link to comment Share on other sites More sharing options...
CapZark Posted April 9, 2010 Author Share Posted April 9, 2010 It came from my brother's house. He had a new whole house system installed and this old unit was discarded to the basement. This is the way I found it when he asked me if I wanted it. Otherwise, it was probably headed for the dumpster. The installers just diked all the old stuff, so there you go. I seem to wind up with a bunch of stuff in this kind of condition, but hey at least the price was right [] Quote Link to comment Share on other sites More sharing options...
Islander Posted April 9, 2010 Share Posted April 9, 2010 I seem to wind up with a bunch of stuff in this kind of condition, but hey at least the price was right Lucky you! It looks like a nice pro amp. Could the "C" in the model number mean it's a Canadian version? Quote Link to comment Share on other sites More sharing options...
CapZark Posted April 10, 2010 Author Share Posted April 10, 2010 Thanks Kouack. I think you just solved my problem. Once I get the pre-amp line signal into this thing with the cables you suggested, I should be good to go. And I think Don is right about the other inputs. I bet they support transformers. How that all works, I have no idea. I appreciate eveyone's help on this. You folks help make this the best forum on the web. Quote Link to comment Share on other sites More sharing options...
kouack Posted April 10, 2010 Share Posted April 10, 2010 I if stand correct those are to plug a crossover like the CS800 peavey, if you really need to use 2 ways active, it would probably be cheaper to get an external electronic crossover since you do have you buy them anyway.

wuzzzer Posted April 10, 2010 Share Posted April 10, 2010 The big round thing are usually for optional Crossover, the cable above is what you need, i do have 6 pro-amp connected to my AVR with that type of cable. That's the exact cable I have going from my Marantz to my Samson pro amp for my sub. Works like a charm. You can also get RCA/XLR adapters if you don't want to order a whole new cable but the cable from monoprice is made very well and with a 25 foot cable there's zero hum or noise from my sub.

CapZark Posted April 11, 2010 Author Share Posted April 11, 2010 Perfect. I ordered two and should have them this week. Thanks again. Quote Link to comment Share on other sites More sharing options...
CapZark Posted April 14, 2010 Author Share Posted April 14, 2010 Just received the cables and they worked like a charm. The amp is up and running. Sweet. Quote Link to comment Share on other sites More sharing options...
