Members RoadRanger Posted February 28, 2012 Members Share Posted February 28, 2012 AFAIK it is the only 2 ohm capable 4 channel 2U amp under $1000 (maybe under $2000?). But personally I'd run an IPR3000 for mains/subs and an IPR1600 or two for monitors over that amp so my whole show wouldn't go down if an amp failed .

Members RoadRanger Posted February 28, 2012 Members Share Posted February 28, 2012 2 ohm capable at that power level for how long?Good question - I've not seen any published tests with a pair of 8 ohm mains on one channel and a pair of 4 ohm subs on the other for the NU3000 (which this appears to be two of in one box). Under normal usage I'd expect it to be OK - maybe not with electronica with lots of stoopid loud sine wave bass stuff going on... Link to comment Share on other sites More sharing options...
Members Unalaska Posted February 28, 2012 Members Share Posted February 28, 2012 There are a few 4ch amps on the market, not many user friendly though. I just bought a Carvin DCM2004L in dec. 300w x 4 @ 8ohms, 500w @ 4, not rated for 2. It's a monitor amp. I had a shallow 6u rack sitting around, put it and 2 eqs and a patch panel for the speakon outs (6ft 1/4 TRS tails live attached in the rack) along with a power strip. Works great! 25lbs, 4 mixes w/ eq. I've even sent it out on a small pa that was L/R + 2mix and worked like a charm for that. For high powered 4ch amps you're talking serious $. Right now there is no UL approval for the behringer and who knows if there will be. It's tempting to have that power in a small space, just wish it had nothing to do w/ behringer. I just sold 2 heavy yamaha amps. I've got cash and thinking about ordering 1 more DCM2004L. Or 2 peavey IPR1600's. But size and weight.... Link to comment Share on other sites More sharing options...

Members Zeromus-X Posted February 28, 2012 Members Share Posted February 28, 2012 I'd still be scared as hell of running my entire rig off a single poweramp. I've had a poweramp fail into permanent protect mode (Yamaha CP2000) and fortunately it was for a drum monitor, and I was the drummer... so I dealt with it. At least with an amp for tops and an amp for subs, you can limp through the show if either goes down (obviously using the sub amp for top duty should the failure occur there, hah). But with one amp, if the magic smoke comes out, you're totally done with FOH, there's no recovery... and you'd better hope the monitors are loud enough. EDIT: Wait, biamping for mains and running two monitors on it? Are you saying you'd be powering mains AND monitors off the single amp? Jesus, that'd be even worse if it fails... you couldn't even flip the monitors up on their sides and power the show with 'em. Link to comment Share on other sites More sharing options...
Members DaBender Posted February 29, 2012 Members Share Posted February 29, 2012 OTOH - for $400 you could have an insurance policy that would eventually serve as a replacement. Link to comment Share on other sites More sharing options...

No...I'd have another amp(s) near the stage or at least in the truck. I would just like to be able to load a single mixer-over-6U case with a full set-up. Right now, I need a few spaces reserved for a couple preamps and eq's. Link to comment Share on other sites More sharing options...
Members Rottdoggie Posted March 19, 2012 Author Members Share Posted March 19, 2012 Seriously though...does anyone in the QSC or Peavey camps know of a similarly-configured 4x that is on the horizon? I would LOVE two crossed-over amps in the same 2U chassis as two others. Would fit my bill perrrrfectly... Link to comment Share on other sites More sharing options...
Members agedhorse Posted March 19, 2012 Members Share Posted March 19, 2012 These days, most folks that are crossing over will take advantage of something like a drive rack with accessable eq. Just my casual thoughts. Link to comment Share on other sites More sharing options...
Members Unalaska Posted March 19, 2012 Members Share Posted March 19, 2012 It is a little scary running mains and monitors off one amp. I can say though that having a separate amp rack for mon and one for mains does help in terms of amp failure. If a 4ch mon amp goes down totally then just put the stereo system on 1 channel of each mains amp (HF/MF/LF) an patch in and get 3 amp channels there. Not perfect but doable. 4ch amps are rare and hard to sell. By the sales numbers it makes them more expensive to produce smaller quantities and that cost gets passes on.

Members Flogger59 Posted March 19, 2012 Members Share Posted March 19, 2012 This brings back memories of when I roadied backline 30 years ago. The headliner was to appear at a make or break gig for the record industry, and someone had the brilliant idea to run all the FOH tops (S2s) from an experimental amp called The Brain. 10,000 watts. Incredible engineering achievement that seemed less so after half an hour of two guys showing the audience buttcrack while trying to figure out why it wouldn't work.

Members Dogoth Posted March 20, 2012 Members Share Posted March 20, 2012 Behringer does come up with some great ideas occasionaly. It's just too bad they're implimented so poorly. To this day no one makes a DSP unit with 3 in and 6 out (for 2 way + aux fed sub the ultra drive unit works OK) for less than $2000 (One of the DBX driverack 8400 comes close). It's a system that many people use yet is unsupported by the industry (except for Behringer). Maybe some people should be ripping Uli off but actualy building it right. I wonder how he'd feel being on the other end of a loosing lawsuite? just a thought. Link to comment Share on other sites More sharing options...

Members Dogoth Posted March 22, 2012 Members Share Posted March 22, 2012 Check out the BBE DS48 I think I did look at that unit once. Wasn't that the one you gave a poor review to recently? It couldn't be much worse than the "B" unit though :-) Thanks Unalaska, Nice to know there are still people with their fingers on the pulse of the industry.

Members agedhorse Posted March 22, 2012 Members Share Posted March 22, 2012 Yes, that's the one I reviewed. Read the review carefully, as long as you undertsand the limitations and the parcularities, it's a viable piece... at least as viable as the "B" units (which I haven't reviewed yet, the only ones I have seen in the field are already non-functional).
