[QUOTE="Scott Harris, post: 203693, member: 1861"] This is a huge can of worms, but I'll give is a shot. That mixer is rated by the Yamaha marketing department as a "peak output" of 500 watts into a 4 ohm load such as your pair of monitors or mains. If you look at the spec you will find that it's really 125 watt amp at 4 ohms meaning 60 watts going to each 8 ohm speaker in your setup. (The amps sees the 4 ohm load of two 8 ohm speakers, but each speaker gets half of that power when you have 2 on the same amp channel.) Buying amps depends on your budget. You could buy a decent 4 channel amp like a QSC PLD 4.2 giving you a true 400 watts to each speaker for $1,000. Seems like overkill unless you have growth plans for that amp. Since you are running 2 channels now, you could stay that way and use a 2 channel amp such as a QSC GX7 which would give you about 400 watts to each speaker for $600. For less money you could get a QSC GX5 giving you about 300 watts at each speaker for $400. If you are lucky you may be able to find a GX7 or GX5 used locally for about half of retail pricing. (I'm just using QSC for reference, these could be Crown, Peavey, Crest, etc. amps.) [/QUOTE]
