Behringer iNUKE4-6000 Power Amp

#1 Post by SimonD »

Hi Folks
Has anyone tried these before? From what I can gather they have 100V - 260V power supply rating so no dramas importing them. I know Behringer has a shady past but current reports are that they have gone to great lengths to improve their reliability. At US$349.00 it's not a huge gamble either.

I've just looked at these recently, think of it as 2x NU3000 in one rack
they're good for about 5-600W per channel in to 4 ohms, but don't like sustained output and have no Power Factor Correction which is a bad thing when your power source isn't great - ie, long extension leads or generator

Where have you found the info regarding PFC? As far as I know, since 2008 all appliances sold in Europe rated for over 75W require PFC, and I'd be surprised if this didn't somehow apply to Behringer products.
In build order:
O12 with no tweeter.
3 x WedgeHorns.
2 x Jack 10 without tweeters.
2 x DR250.
2 x 16" T39
1 x Tuba 24
2 x SLA Pro (sort of...)

I put one in an install recently. As with most things "B," it came with the understanding that it should only be expected to work during the warranty period. Anything being that is gravy.

That said, it did pretty well. Sounds clean, clips nasty, which is about what was expected. Didn't measure it but the power output felt about right (working with cabs I know well).

If you're on a budget and need an amp, it's an amp.
99% of the time, things that aren't already being done aren't being done because they don't work. The other 1% is split evenly between fools and geniuses.

Definitely NO PFC...

Settle down and read:

http://forum.speakerplans.com/behringer ... 69202.html

The 4-6000 the same as the NU6000 - both contain 2 NU3000s, but the outputs of each 3K amp are already bridged with the NU6000.

Note the current draw at the bottom of the first page.

Current drawn is in purple. That's 80A current draw!!!

The OP is questioning the NU46000 which I inquired in a recent thread. Without scrolling through the many pages (mostly of pics) of your link, I was thinking of the same amp; two channels for two OTop 112s for stereo and two for monitors. At 440W (Behringer specs), even half that would be plenty for OTops and over kill for mons.
2X OTop 112, 3012HO, melded - 2X T39, 27", Lab 12 - XF 212 - 4 DR250, 2 melded, 2 straight
2 20" T39 3012LF - WH10 - WH8 - in the shop - 2 more 20" T39s

Don't believe the hype! The NU3000s that I have are ideal for running 2 subs per side. They output 315Wrms@8Ω (50.2V), 620Wrms@4Ω (49.8V) and 1040Wrms@2Ω (45.6V) so for the 50V of a T30 (and many other BFM designs) it is ideal for 8Ω and 4Ω - the only issue here is that you have to use a limiter, which is going to drop the signal a lil'. As the 4-6000 is just 2 of those amps in the same chassis, you can be pretty confident that your system will run good.

Oh, just re-read your post... you're not even using these for subs. :wall: Ok then... start again. For most BFM tops the amp is fine. I have used it with Otops 2512 loaded and DR250s 3010 loaded. For the Otops it was good, however I do find it under-powers my DR250s with the 3010 by just a little - I cannot get the speakers to sound bad at any point until amp does the job for me by clipping.

This amplifier is intriguing me... It can be had for less than $300 and would allow me to have stereo mains when using recorded music and will almost drive my subs to their limit. With both subs on one channel there is even an extra channel for monitors. It could be a good starter amp, along with that closeout Driverack PX I bought last year, to bring up my 2xDR250/ 2xT39 system.

While I'd have to set the sub limiter below clipping (about 50V for this amp?) rather than the 55V that 3012LF loaded T39s can handle, that's less than a dB difference.

Is my thinking sound?
