OK to start off, the band I am in is a 4 piece alternative rock band, we all know alot about our own instruments, although were always open to help, but none of us know a thing about a PA system so please forgive me, Im tryin to get my head around all this. Currently we have a Kustom 4 Channel 120 W powered mixer with 2 Kustom passive speakers. Were looking to do a little upgrading. 2 150 Watt Powered speakers and a new powered mixer. But we dont know what to look for. The venues we'll play will be small, bars, clubs things like that for now. So i was wondering if you guys had any suggestions as to how big of a mixer we should look at (wattage wise), we currently only run vocals through the mixer, like I we dont know alot about live sound, so not sure how many inputs we should be looking at either. Were on a fairly tight budget, id say about a $1000. Any help and advice would be greatly appreciated Thanks.
