sorry guys but am a noob in this & i have a ****y KenWood amp with so little inputs & outputs & am planning on getting a Yamaha RXV650 & i was looking at it's PDF manual & looking at the back of it & found that i has many many things i don't know what they are used for so plz help me with my questions: 1-What's the Presence channel??? 2-What's the monitor out?? 3-Why it has too much Svideo out puts (7 of them) 4-could i configurate the RXV650 with it's display only or i must use the on screen display on a TV to get all options??? 5-the amps power is stated as 130w/165w 8ohm/6ohm does that mean when i go down with impedance on speakers i will get more power??(is that means my Wharfedal 8.4 150w 6ohm speakers will get 165w from the amp instead of 130W?) 6-I really want to know this,i have a Sony DVD (DVP-NS305) which i always connect it directly to my TV with the svideo connector,if i get this amp should i connect it to the amp & them from the amp to the TV??& if yes why i should do that??also i noticed that the amp has Component video (Y CB CR) & my sony DVD have them but my TV doesn't,so can i get any benifit from having it on Amp & DVD???? sorry guys for all this questions but knowlage is really needed here.
