(If this is wrong place for this question, let me know I'll correct it) First, Hello all, this is my first post on this forum. Second, a little explanation. My father began a church a year or so back and set up a decent audio system to run it, albeit not perfectly. Randomly get cracks and the noise level needs constant adjusting, but it works. I, being his son and being the only musician in the family, decided to help in making it better recently. And I am great on guitar and piano, but I am woefully uneducated in sound levels, EQ, mixing boards, mics, etc. etc. so to the questions. 1. I just got a Yamaha GF24/12e and I have no clue on how to set up. My first problem is about the amp. I don't know what kind to get at all. To help answer, I believe you need a list of what will be used, so here you go. 1. 3 wireless Mics, 2 cord mics. 2. 2 floor monitor about 10-12 inch 3. 2 Stand up PA speakers 4. 1 Electric guitar(min. effects boxes. Distortion and maybe a delay.) 5. 1 Acoustic guitar 6. 1 Electronic Drumkit 7. 1 Electric Keyboard 8. The computer for playing mp3's and recording. If I'm not mistaken, that will be 13-14 channels(?)(mono?) with more to be added later. 2. Its basically a square room about 20x30 with concrete walls, so any suggestions on where to place speakers and sound booth? 3. Any suggestion on links to other threads about setting up the mixing board EQ etc.(I know i can look through but some of you might know good concrete ones I looks over, so just in case) That is it for now, for lack of educated questions to ask, since I'm new at this. Any help is appreciated and if it matters I'm on a tight budget so buying things is not a top priority. Thanks in advance for any answers.
