Hi, I was wondering if anyone had prior expeirence with DVA line arrays. The theatre where I work bought a brand new dva line array last year and we have been getting reapeted total faults(dead amp) on various amp modules. They just go in fault and then mute for no apparent reason(with no signal input in standby) I've had to change 3 amps since they were bought. Turning off and on as the manufacturer recommends does not change anything. Yesterday, another 2 modules were in fault. By the end of the 1 year garranty, I'll probably have changed all 8 amps.(4 speakers per side) - they are active speakers with built-in amps - they have protective limiters on the amps and driverack - they are hung at 22' - there are no fans for dust to accumulate - 2 speakers per 15a circuit (3.3 amps each) Anybody with ideas or experience is welcome to give "input" ahahaha. And if anybody is looking to buy them, Don't! Thanks!
