Got it. Thank you!!

Also mono should allow for different impedance load on the channels vs stereo which requires identical load.

So for example on dual mono you could run a 4ohm speaker on A and an 8ohm speaker on B.

My inuke NU-4 6000 when I turn it on, all the channels light up except for channel B. What does this mean?

Read through most of this thread. I was looking for a less expensive alternative to the XPA-3. The speakers I want to upgrade to (rf-7 rc 64II) I called klipsch and they said to give the speakers 200rms each. With that 4th channel I could run a Si 18 all for under $350. Not sure I can argue with that price point.

Curious though, I turn my receiver up to -10 and its very loud to my ears. Would adding all this additional power make it clearer at that volume. I dont think I would need more than what I currently have to be honest. My rooms 3,377 cubic feet.

Also, I dont have a rack for my current 3000dsp, could I stack the NU4-6000 on top of it without any heating issue?

You don't have to worry about stacking and heat. These are force-cooled amps that are intended for use in hot, rack-mount environments.

So before I pull the trigger on this amp as it seems to be the best deal around for a 3 channel. How would I set it up? I never used an external amp for my speakers before. Do I hook it up with the pre-outs like I would my sub and if so what volume did you guys leave yours at when you do room calibration. I have a denon x4000 avr.
Also, is each of the 4 channels different. So I could run LR in stereo, my center and then a sub of the 4th.

I am using my NU4-6000 that way...L,R,C and a sub. Yes, use the pre-outs on the Denon and note that the iNuke doesn't accept RCA. I used the internal test tone on my AVR to set the input gain on the iNuke to produce 75dB at my LP...IIRC, the input sensitivity is different from inputs A & C and B & D on the iNuke and you will need a Speakon connection for the output side to your speakers.

That sounds excellent.

Hers my shopping list.
Fan x2 (its what I used in my 3000dsp)
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER
(using this cable just for the speakon connectors, its cheaper than buying them individually and I have an extra one already)
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER
XLR Male to RCA Male
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER
nu4 $350
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER

Total of $403.05. I dont think I could find a much better deal for a 3 channel amp for my fronts and an extra channel for a third sub.

I bought the NU4 6000. I'm looking to use it in a L/C/R mode using a Onkyo SR 805 A/V Receiver's preouts. I assume from reading that all of these amps fans are loud in a HT setting. If need be I'll get 2 Dynex 80mm cooling fans from BB for $5 bucks a piece. Can I use the Behringer amp on a 120V 15 amp circuit ? I have a SVS PB10 sub so will it be worth adding the amp to it ? If so, what cable I think I have 2 sub outs on the Onkyo 805. Both for powered subs. My main speakers are Dahlquist 20i's which love power at least 300 watts per channel in 4ohms. My center channel is a 8 ohm Klipsch klf-c7 that can handle 600 watts max. Above I read that XLR Male to RCA Male cables are what is needed to run from receiver preout to the amp. Would I need 3 mono cables, 1 for each channel. And, where does the Speakon adapters fit in ? Are they needed just for a sub connection ? If so, please explain how. What about ART CLEANbox ? Or, Furman power conditioners. Are they helpful ? I'm new to this type of setup, and want to do it right, so feedback is highly welcome. Thank You.

Got the amp hooked up. I have my av set to +5 and the inuke turned to about half way. I am herring the buzz noise in the speaker. I removed the ground from the plug. Going through the sub I here no noise. Only when I am in the speakers?

Any idea how to get ride of that.

^^

I have negative trim values in my AVR for the L/C/R speakers and the gains on the amp are at the 2 o'clock & 3 o'clock position...the speakers and sub are dead quite. I lifted the ground on the iNuke as well. I would start looking at the other A/V equipment hooked up to your AVR and see if they are causing the problem as well as looking at each one of the XLR male to RCA male cables.
