To jungletekno, what you need for a big pa

Alright folks, there's a user called Jungle Techno. What he wants to do, he wants to get his own big PA system in the near future. Right, so what is a big PA system? I've done a similar sort of thing on this before but I'll do a quickie for you now. Right, well, you know, 10 watts is like something you'd have in your house, 100 watts maybe for a small disco, 1000 watts for a bigger disco, 10,000 watts you'd have a nice nightclub, 100,000 watts that's like the sort of thing you'd have in a huge event. Now then... 10 watts is .01 of a kilowatt. A kilowatt is basically 1,000 watts. So then you'd have .1k which is 100, 1 kilowatt is 1,000 watts, 10,000 watts is 10k and 100,000 is 10, sorry 100k. Now then.

How all this is set up is basically this. If you imagine there's your music, that's your mixer, your input, all your microphones, if you're a band, that's your turntables, your CD players etc. Then what it goes into is X over effects lots of other gubbins and things and nice things like that. Now quite often what you'll do is you can get up to like 4 and 5 way but generally if we talk about 3 way so you can work that out on the principle of your mixer bass, mid and treble. What will happen, you'll have say bass out and you'll have lots of bass amps. And then lots of amps for mid and lots of amps for top. And then what happens, you go from the bass amps, you'll go to bass speakers, loads of them. These can be 18 or 15 inch. And then the mid amps will go then to the mid speakers which could be say 10, 12 or 8 inch. And then the top amps, that was a dodgy picture, it didn't work. And then the top amps then will go to high frequency horn loaded drivers because these are called compression drivers as well. And these will go to either 3, 2 or 1 inch.

If you want any more information on this, look on the internet and just look for Pro Audio PA. You'll find the likes and makes of Nexo, which is a very, very good make, also Lab Groupin, which is a very good make for amplifiers, Crown, Macrotech, that kind of thing. Also RCF do another make which is EAW, Eastern Acoustic Works. So just look up some information on those, type in Pro Audio PA and you can't go wrong. Thanks for watching Practice & Enjoy.
