P.A. Equipment

hey,i have 4 jbl 4733a,4 jbl 4719x,for my speakers.i have 2 qsc 1850,2 qsc 2402,2 qsc 2450 and 2 beringer 4000 .im thinking of running 1 1850 for hi's control knob half power left and right.Mids one berginger 4000 bridged for tw0 jbl 4733 mids,2 2402 bridged for 2 4719 1amp per speaker and 2 2450 bridged for the other 2 4719. would this be a good way of setting them up ?any insight would be awesome ...

Match your ohm ratings from amp to speaker load. Run your amps near full and control volume with the board.

so for to cabinets they will be running at 2 ohms and recommended ohms for qsc 2402 amps are 4 ohms bridged mono at 2400 watts will that be ok for the mids on the sr 4733a bi amped and ill be running the qsc 2450 at 4 ohm bridged mono for each 4719x subs so im thinkin it will be ok

I try to keep it really simple with my stage gear as it can get quite complicated for the average individual. ( that would be me )

Maybe this will help:

This looks like a lot of gear. Audience of 5000 plus? My simple rules of sound reinforcement are:

KISS -Keep it simple sherlock and only bring as much gear as you need to cover the audience.

Avoid 2 ohm loads. Bad things happen at 2 ohms even when an amp is rated to go there.

Testing and measurement- Set up your rig well in advance of your planned show, run some music through it that you know cold. Walk the arena listening for hot spots/dead spots, balance and test for SPL with a meter. Adjust until you can get good clean coverage and SPL without ever clipping an amp. No clippy- no breaky.

YMMV

PA system for 5000? Rent local (or better yet make it part of the required contracted backline), don't truck it around!
