Edit 9-2023: All 4 of my NX6000D amps have died, one after another. None of them start up anymore, which makes it look like a fairly simple component somewhere in the power supply has died. Unfortunately, absolutely no information is to be found about this issue so fixing it yourself is impossible without a master's degree in electronics. I've brought 2 of them to a couple of repair shops, but nobody will even touch these amps.
Too bad, as they legit sounded great, but the extremely poor build quality makes them essentially useless.
This amp is unbelievable. I have two of these to power my large W-bin Subs and they perform with ease! The build in DSP is powerful, quick to set up using a PC and cable and sound as good as the DBX Driverack I was using prior to these amps.
The light weight means more power from a single rack as the racks just because easier to carry. Currently I'm getting about 18 kW from a rack that weights only 25 kg which is amazing in it's own right. The D-class amps however require a clean (and plentyful!) airflow to cool, so do NOT obstruct airflow to these units in any way. If you are going to close the rear of the rack with fancy ventilation rackplates, it's pretty much mandatory to also install one or more cooling fans to prevent overheating equipment. This is however required for all D-class amps (they are all heat sensitive) and not so much this particular model.
The styling of this amp is something Behringer hasn't done before. In most Behringer product (like it's predecessor iNuke 6000) you can clearly see the typical Behringer design features, but not in this one! They have clearly put some thought in creating this amp.
It'd say the one really noticable con of these amps is the lack of XLR through output to daisy-chain these amps (which would be very useful considering the built-in DSP). Nothing a rack-mixer won't fix though!
All in all a very nice amp for an amazing price. Highly recommended!
