My band needs a PA system to cover smalltime house parties and smaller/medium outdoor parties. Like, 100 people max kind of thing. Would this be adequate? http://pro-audio.musiciansfriend.com/product/Yamaha-EMX212SBR12-PA-Package?sku=630196 or maybe this... http://pro-audio.musiciansfriend.com/product/Yamaha-EMX512SCBR15-PA-Package?sku=630199 We really just need something relatively small, lightweight, inexpensive, and reliable. We've been borrowing a friend's PA or using a vocal amp for smaller areas. Only plan on running vocals thru the mains.
