Behringer NX3000D

The NX series amplifiers really are worth their price. -Especially ones with DSP.

But first of all, I do recommend everyone to actually seek real measurements of the equipment they are about to buy. These reviews here are merely subjective experiences. For example if you read an amplifier "sounding warm/bright", "revealing more detail" or "lacking bass" etc., that is just bogus. This is simply not what amplifiers do. They just amplify the signal, not alter its tonality. If it does, its either defective, or a tube amp.

There is, however, differences to these pieces of electronics and Behringer certainly delivers good quality at exceptionally low prices.

Power: NX1000(D) outputs ~26 Vrms per channel, or ~52 Vrms bridged.
this corresponds to ~170 Watts per channel (4 ohms) and 680 Watts bridged (4 ohms).
NX3000(D) outputs 49 Vrms per channel, or 98 Vrms bridged. This corresponds to 600 Watts per channel (4 ohms) and 2400 Watts bridged (4ohms).
This really is outstanding performance in this price range. I still want to point out that these are falsely marketed as delivering 2x300 and 2x1500 Watts of power, which they do not. Even briefly.

Signal to distortion is about 81 dB (<0,01%). While this is average performance, it's inaudible, even if you played only pure sine tones.

Signal to noise is 100 dB. This is average within affordable "pro"amps, and actually the NX1000(D)-model produces slightly less audible hiss, than a similarly powered Crown XLS amp. This hiss might be a problem, if you are using big, sensitive speakers near field.

DSP functions are awesome. Crossovers, 8 fully parametric filters per channel and adjustable limiter. Yeah, and Dynamic EQ that might be useful as a compressor for full range speaker or just simple bass boost for lower playback levels, for example. personally I don't use it.

The fan is taking air in from the back of the amp and blowing it trough and exiting front. In my opinion, this is wrong way to do it, but it serves a purpose blowing directly to main amp stage.

The fan IS actually temperature controlled, but it is so poorly implemented that in practice, it's not. the fan whirrs nearly full speed even when cold. And it is noisy! Fan replacement is easy, no need to solder just plug and play, but apparently voids warranty. This is something I am not OK with. In my opinion it's same as voiding warranty for my car, because I changed tires myself. Little provoking example, but you get the point.

All in all, excellent amplifiers for their price!

I've never paid attention to the negative press Behringer used to receive and simply made my own mind up. I have 2 X X32, lots of P16 mixers so when I needed some amps for a new system I spotted these. Initially the draw was the weight, but then I noticed the digital version, and for the small increase in cost went with a couple of these - blind. My intention was to do the crossover in the X32, but once I had them in the rack, I tried the laptop programming of the crossover functions and decided that this would make the rack more versatile for multiple uses, so I just feed these amps with a L+R and leave them to do the crossover functions. Works perfectly. I'm never careful with equipment - my use of every product is heavy handed and I often break 'rules' and these appear quite happy to accept accidental no load, or simple power up by just turning on. They just work. No excessive temperatures, no annoying features. The fans are quite loud, if that's an issue, and I wish they had the choice of XLR and jack, as in some of the Thomann own brands - as you can use these for loopthroughs. On these amps I had to make up cables to do this, but it's a small point. The absolutely best feature of course is the weight - as in they weigh so little. I have a Thomann 2400 amp in the same rack. It weighs more than the two Behringers combined, plus some! The LCD screens on the front are quite narrow angle, so reading them from above or the sides can be tricky - you need to be face on to really see the detail - if like me you wear varifocal glasses, it's difficult to read without squatting down, but that's a minor point. I'll certainly buy more of these.
