[QUOTE="Lisa Lane-Collins, post: 10782, member: 2967"] I kinda mostly almost have my head around this (amp should be rated halfway between the rms and peak capacity or something to that effect, and you can supply a more powerful amp, but without system protection, users might blow up the speakers right?) I don't feel confident enough with my knowledge to send this amp and speaker combo out without first asking advice and or asking, is there a way to measure the precise output of the amp? The speakers and amp in question are a pair of EV SX300s and a Behringer inuke3000. So, speakers are 300w continuous, 1200 peak at 8 ohms. The local hire house sends them out with amps that are 500w a side....which is probably pretty much spot on. I don't have any amps at that rating though, just these goofy inukes. I haven't a clue what their true power output is because Behringer has not obliged to provide accurate information. I found a post online from someone who tested them and seem to recall that post saying they put out about 700 a side at 8 ohms....I'm gonna assume the limiting is useless and that the client will milk them for all they have.... I do have a compressor I can use to limit the rig if I need it, but being able to measure output (before, after) would make the process a whole lot more physics and less guess and hope. [/QUOTE]
