Behringer NX3000D

I purchased this amp as a replacement for my 19 year old Dynacord S1200, for my home theatre system. I wanted to try a D-class amp, and have only had good experiences with Behringer in the past, so I went for the NX3000D. The sound quality is excellent. On par, or better than the S1200 before the caps started to dry out.

I left it switched off for a week during a small vacation, and when trying to turn it back on, it was completely dead. Opened it up (risking the warranty) to see if the internal fuse had blown. But it was intact. So the internal power supply had apparently waved goodbye. There was no apparent catastrophic failure. No blown caps or discoloured components.

Being an electronics engineer, I know that these things happen, but at the same time I believe the construction leaves very little margin. At the same time it comes at a rock bottom price, and you can't have it both ways.

I've returned it and I'm expecting the repaired unit back, or an equivalent replacement. I'm not giving up on it. At least not yet. :-)

I'm using the amp for a home cinema.
a combination of subs and bass shakers. 4x15" on one channel(subs) and 2x12"(bass shakers) on other channel. i've got it to deliver quite linear down to 7hz which shakes the whole house!

using an measurement microphone(not included) at listening position and REW to fine tune the peq to avoid some room nodes and low end drop of of the closed subs.

It sounds great with a lot of punch!

Pros
Build in DSP with a lot of features, x-over, peq, limiter(watt), dynamic eq, delay, user presets and so on. individual per channel or combined.
Alot of power!
Lightweight
volume knobs on the front with distinct steps.
you get a sticker..
USB connection for pc software for tuning. most stuff can be done via front panel too but more via pc software.
lots of bang for the buck
great control of speakers

Cons
peq don't go under 20hz (you can still boost under 20hz with some clever use of the x-over and a first order filter)
LOUD fan, no speed control. but can quite easily be changed to something quiter if you need to be in the same room. warranty is probably voided by this thou..
no power remote input.

I would recommend it to anyone.
