Now i know this is not really the equipment for this forum, but i have a problem with the unit and some unhappy Filipino colleagues,

if you provide an audio signal in you can see the small bar graph going up and down in the display so that appears fine

however there is no out put, the speakers are JBL RM8 which came with the amp, each speaker cab has a resistance of 7.2ohms

the open circuit voltage peaks around 80v on each output (this was just a quick measure with the multimeter) when the speakers are connected the voltage is around 32v max, can put a scope meter on it tomorrow,

not sure why cannot get an output, we have tried all combinations of inputs but no luck

any feed back or ideas are welcome, 

cheers

No, it is not a line array it is some well stacked boxes...............
