the labor day code for parts express is still active. add a $0.29 screw as filler to break the $500 mark and use code LDFIFTY at checkout to get it for $450

Call GearClubDirect and ask for the best price. They shipped within 2 days too.

any opinion here? About to pull the trigger....
post #94 of 133
if you go crown xls, why not get the 2500, wire the drivers in parallel for 2 ohms per channel and run it that way? or do you need independent eq on each driver?
post #95 of 133
I have a deal pending for 1500's at about $275/ea (new). I need an extra anyways for my outdoor subs so my thought would be to run a pair of 1500's for my basement system and maintain some headroom vs. loading a single amp down (which is how I was running my EP4000). With a Class D, is the concept of headroom and damping factor no longer relevant?

Did the fan mod for the 2 fans with some decently powerful yet silent 12v Lepa fans from Newegg. I went with these over the Noctua because they were cheaper, more powerful, and not much louder.

The amp is whisper quiet now. There is also no "shroud" inside like the previous Inuke amps.

No, headroom and damping factor have the same relevance as ever. Damping factor is less of a consideration in a system that has been equalized in place, but that is true for amplifiers of all kinds, whether linear or switchmode.

Cool, good to hear! Would you mind sharing the model/part numbers for those interested?

The Lepa is over 20% stronger than the Noctua, half the price, and only a few DB louder (still whisper quiet). Would be good to use on any 12V Inuke.

I was considering buying the NU4-6000 until I noticed that 2x NU3000 would cost me $7 less than 1x NU4-6000. For $150 more I can get 2x NU6000, looking at it from a bang-per-buck perspective, paying a little more for 2x the power makes more sense.

Unless you are really short on rack space, I would not recommend this amp. Not in Europe anyway, prices may make more sense in the US or elsewhere. I'm not bashing it, I have a rack full of Behringer amps and other Behringer stuff. The NU4-6000 simply does not make sense to me at the current price, it should be cheaper than two NU3000's.

Also, has anyone properly tested this amp? How much power does it put out before it shuts down? Like others said in this thread it looks like two NU3000's in one case sharing one power supply. Has the power supply also been beefed up to twice the size of the one in the NU3000?
post #101 of 133
any suggestions on a line driver that might increase input voltage? I've found on both my setups that the Crown needs a lot of gain.

I am using this active DI box to do exactly that. Note that it has a fixed 20dB gain, you might need to attenuate the signal again to avoid clipping the input of the amp. (or look for an active DI box with gain controls)

2x NU3000 = $600

1x NU4-6000 = $470 shipped.

I fail to see the big savings you get from having two amps? 2 bridged channels have way more power than 2 of my 18" SI's will ever need, and sounds just as great as my EP4000 did.

That's what I get for living in Europe then. Overhere the price difference is almost nothing. smile.gif I am currently running 6x EPX4000. 2 of them are bridged for the subs.

Found a couple of options on P-E.

That will work for my outdoor setup but I've already got balanced out on my home theater so looks like I need a DI type box.
post #106 of 133
The Cleanbox will work fine.
post #107 of 133
A line mixer with balanced in and outputs would work even better if your source is already a balanced signal.

http://www.parts-express.com/pe/showdetl.cfm?partnumber=248-6306

''Usable as 6-In / 6-Out level matching amplifier or direct inject (DI) box'', it can provide up to 15dB gain.

I was looking at that exact unit for my balanced system with two XLS-1500's and the Cleanbox for my other one.
post #109 of 133
I have six cleanboxes. They work great at boosting the low voltage from my Onkyo Tx-Nr 1009 to my pro amps.
post #110 of 133
PGT, or anyone else, PM me about Bump boxes, I have several I don't need anymore. A few cleanboxes, an ATI mm100 which is quite nice, and a samson s-convert.
post #111 of 133
and I just ordered one...
post #112 of 133
Haha, oh well.
post #113 of 133
I just picked up a NU3000. Is there any way to have it power on when the rest of the system powers on? I didn't immediately notice a way but thought I would ask. Thanks!
post #114 of 133
Get a SmartStrip
post #115 of 133
Have you used a smart strip with a power amp? Will there be any issues with the high current draw of an amp connected to such a power strip?

yes, my whole system including an ipr3000 and 7x100 w/ch receiver

I'm considering an NU4 6000 as a much less expensive and possibly better alternative to an Emo XPA-3 to power the LCR channels of my 9.1 ch HT system but I don't know what I'd do with the fourth channel. My XV-15 subs have their own amps so that's not an option. Can I bridge two channels for the center and run the other two to my left and right channel? I hate to waste this much power on just the surround channels.

 

Can this $470 class D amp possibly sound as good as the $719 class A/B XPA-3 for $249 less? Opinions?

post #119 of 133
going rate on used XPA-3's is $500. I'd be inclined to go that way, given their 5yr warranty
post #120 of 133
sure, you can bridge one pair of channels and use the NU4 as a 3 channel amp. Download the manual from the Behringer site for more info. You might have to rewire a 4 pole speakon connector because the inuke series only have speakon outputs.
