Aight, so my band just had a gig last night. The venue doesn't supply the bands with a PA, which we found out just hours before we had to go on(yay!). Fortunately our guitarist/vocalist had one, but its REALLY inadequate, even for just vocals.
Its a bar/restaurant/chill area so we don't need blaring amounts of volume. We mainly want something that'll give the vocals a lot of clarity, headroom, and richness. The drums are already loud enough and carry well, as do the bass and guitar.
SO! Since I know nothing about PA systems, what are you people's recomendations? For our purposes right now all we need to boost up above the band is the vocals. So what is a powered head/board/and set of speakers that would fit this application, as well as scale up to miking a full band setup in the future with additional purchases of speakers? We don't want to buy something that won't hold up over time and become just another piece of junk. In otherwords, we want to splurge and have something nice that is professional, and expandable.
