Hey all, got a couple of quick questions to ask about Line Array systems.

1. http://www.jblpro.com/catalog/general/P ... =124&MId=4
This states that this line array element is 'powered' does this mean it dosen't not require an amp or that simply the speakers are powered? Or something else?

2. http://www.jblpro.com/catalog/general/P ... =121&MId=4
This element states that it is tri amplifiers meaning the audio signal is separated into 3 separate bands however do i need three amps to power or will one do the job?

Apologies if these are basic questions, still pretty new to the live sound world.

Cheers in advance.

Powered means it has it's own amplification built in.

One amp is needed per band.
