Have run with these steps now for a while and that the literature indicates the effect of the maximum power is perhaps to take in but a test have measured this in 1100watt 8 ohms about 2000watt in 4ohms load
read the test here http://forum.speakerplans.com/behringer-inuke-nu6000-vs-kam-kxd7200-bench-tested_topic69202.html
However, reading about people who had problems with the Red Ring protect but register the product at BEHRINGER's website, you get 3 years warranty instead of 2 years.
The product feels plasticky yes but what do you ask for a product for 3500: - I aftershocks have played with the lab in 2000 that weighs more it costs more and perform proper equivalent. Last party I played with that I played with 2x 10 inch tops and 2st 15tums base bottom only two lights of the stage vu staple blinked and this felt. In order to be a step in 3500: - performs the worst, as a step for 10,000 - and I recommend it quite clear to those who want to have a good start.
