I just retired and I want to do a little djing just for fun. I have no knowledge of hook-ups or settings on the equipment. I bought: aphex 204 exciter dod sr430Q equalizer behringer mdx2200 compressor/limiter behringer super pro cx3400 crossover 1 qsc mxa 2000 amp 1 qsc mxa 3000 amp 1 qsc rmx 4050hd amp. 4 jbl sr4733a speakers 2 jbl srx728s subs or bass cabinets. I plan to use the 2000 for 2 speakers and the 3000 for the other 2 speakers. And the 4050 for the subs or bass cabinets. The equipment is set in the rack just like I listed it. I've read the instructions on the manuels and I've pretty much have everything hooked up. What I would like to know is, is there anyone who could help me with the settings for the exciter, eq, compressor/limiter and the crossover? On this part, I am a lost puppy. I thought I could do it by myself but it's way beyond my knowledge. Any help would be greatly appreciated.
