Members RoadRanger Posted September 13, 2013 Members Share Posted September 13, 2013 FYI Behringer tells me:"The NU Series has regulated switch-mode power supplies which come in a number of country versions. In the case of NU6000 the ranges are 90-110 V, 99-132 V and 198-264 V to cover the world market. The product labeling for the ranges is 100V, 110-120V and 220-240V carry an implied tolerance of Link to comment Share on other sites More sharing options...
Members Pro Sound Guy Posted September 13, 2013 Members Share Posted September 13, 2013 Yes there was another thread on the INUKE 6000 and people blowing 15A breakers up the ying with them.Regulation is the norm in power supplies for this class D design is it not?

Members agedhorse Posted September 13, 2013 Members Share Posted September 13, 2013 No, most are not regulated though some appear to be. There are advantages to regulated supplies but card must be used in the design to address stability of the control loop. This is much more difficult with large dynamic loads, hence the typically increased failure rates with such supplies. I have products with both types of supplies and the raw stability is greater with the unregulated designs. Link to comment Share on other sites More sharing options...
Members Pro Sound Guy Posted September 13, 2013 Members Share Posted September 13, 2013 So the amps performance when these amps are put to the test is reliant on a dam good AC source. Link to comment Share on other sites More sharing options...

Andy, I wonder if the amp failure I saw last week was due to the power supply failing or its control. It was a "boot failure" and the tech thought it was the control, but I suppose a failure to boot could be from either end of this system, no?

I have ran three NU6000DSP and two NU3000DSP amps on a single 15-amp breaker for loud rock outdoors shows and they did just fine. Link to comment Share on other sites More sharing options...

CMS Author Craig Vecchione Posted September 19, 2013 CMS Author Share Posted September 19, 2013 There are only two kinds of speaker that amp will power: Blown, and those that will be. Link to comment Share on other sites More sharing options...
