Reply to Diesel generator for small party in field

Alright people.

Having a small outdoor gathering in a field in UK. I have access to a generator which i believe is rated at about 6kw.

We have a small PA system running off this amp http://cpc.farnell.com/1/1/36886-pow...stageline.html

There will be a few lights but nothing major at all. All LED style lights so shouldnt be a massive draw of power.

I'm presuming this is plenty of power that this amp is giving out?

Is there anything i need to be aware of? The generator has mains sockets built into it into which i was going to plug surge protected sockets before any of the kit.

Any do's and don'ts?
