My church got budget approvals to perform some major upgrades to our ancient sound system and poorly implemented lighting in our main sanctuary. So we started with the main power amps and speaker cabs. All the cabs hanging from the ceiling that never really did provide good coverage to the whole room (not a large sanctuary, but holds 350-400) were pulled down. Good cabs (JBLs) but just poor placement and specification by whatever engineer was in charge years ago. The cabs were replaced by two sets of JBL line array columns mounted to the back wall. Two new crown 1000 watt power amps, allowing us to re-purpose the old QSC's for monitors, and junk the old no-name amps that used to power the monitors. Two new DBX Driverack EQ/speaker management units. Brands new speaker runs for all cabs and monitor points on stage using proper gauge speaker cable (the previous installer used 14-2 electrical). I did all the new cable runs and connector ends myself, so I know it was done right Anyway... this post mainly about the JBL line arrays. Man, what a difference. We finished installing it all Friday, used it for the first real service Saturday night (shook out some bugs), and Sunday was the real test. Boom! What an awesome difference. We still have some EQ fine tuning, plus an upgrade to our subs still to complete. But those two little line arrays serving up the mains just hit it out of the park. I played acoustic Sunday. The coverage from the line arrays was so complete I didn't even need a monitor.
