post #91 of 282
Noah - you asked if you could choose exact frequencies on the iNuke - that question is answered with a resounding yes.






Let's hold some discussion on why you should or shouldn't go with the DSP model. I love the iNuke's DSP, but I'm not yet familiar with the Peavey DSP.

Currently I use a Symetrix 551E five band eq and HPF rack mount appliance and have a Behringer Mic 2200 on standby. I like the iNuke DSP better than both of those - but most of the high esteem is the awesome interface and easy USB connection with real time change application. I don't think the Peavey IPR2 has a software interface to the PC right? Using the little LCD screen on the iNuke is a pain in the butt compared to the software interface!
post #92 of 282
No, I don't believe the Peavey has a PC interface.

So with the USB cable hooked up you can make changes and see them in real time using OmniMic?

If so, nice!

Not exactly, but I see inside the amp where they have seemed to have used a PSB that accounts for larger PS and capacitor banks than those used in the largest (7500) current model. One would assume the crest pro-lites might take advantage of that since the $$ markup would seem to indicate it.

Im pretty sure cookie measured it flat lower than that. I think the -3 point was 3-4hz on his unit. IIRC

The specs page shows the 7500 IPR2 can be used at 2 ohm stereo. If the 7500 was two 3000 unites bridged it couldn't be used at 2ohm stereo.

http://www.peavey.com/products/index.cfm/item/703/116952/IPR2%26trade%3B%26nbsp%3B7500

Yep, and no, too. In order to get the full power of the amp, you HAVE to use 2 ohm stereo. You can't bridge to 4 ohm mono and get full power, actually not even half. Take a look, 4 ohm mono is like 2650 watts and 4ohm stereo is 2400x2, when 2 ohm stereo is 3750x2.

this is an example of it in front of my panamax which has the brightest blue LEDs on it that i have ever seen

the 2 circles should be the same brightness but the light dim is placed in front of the one on the left. thats the original 50-80% one


hey, Sibuna...doesn't the Panamax have a "meter lights" button on the front panel that allows you to control the intensity of the light all the way to zilch??

yes you can turn them completely off, i just thought it was a good to use as an example of how much light they dim. I use them on most other things and I am happy with the results
post #95 of 282
^^^^^^^^^^^^^^^^
Pretty cool idea. Simple solution for a basic problem.
I seem to be able to successfully "tune" them out, but I can see where the bright lights can be distracting to some.

Now, if they only made them for annoying noises!!!!!!!mad.giftongue.gif

I'd be interested in a 7500 DSP.

After reading through this entire thread; I am still unclear if a ipr5000 will trip a 20 amp dedicated breaker.
post #98 of 282
No, an IPR-5000 in regular theater duty will not trip a 20 amp breaker.

Under normal use, the 7500 will not either.

You would need to be doing some torture testing to make one amp trip a 20A breaker.
I run two CE4000s and a 5x200 amp for my mains with EQ, BD player, etc and have never tripped a 20A breaker. (as shown in avatar)

I hit 120+db peaks during movie watching, but don't do sine wave tests.

same here, running a 7500 on a 20 amp circuit with a couple other small devices and have never tripped it even running the subs super hot on demo scenes. If you're tripping a 20 amp with only this amp on a circuit I'd swap out the breaker. I have 3 dedicated circuits to my rack but I have 7 pro amps plus all my other components spread across those...all class D amps though.

Guys - Happy New Year!

Please see the first post with some updated information compliments of BLAH. For the guys that have committed let me know what you all want to do.

Can anybody point to pictures of the internals of the Crest and Peavey? I could only find the ones in the fan mod thread, but that's a 5000. Maybe the 7500 takes advantage of the additional space for filtercaps.

Yo suby, how hard was it to get the OS to play nicely with your sealed subs? Are you crossing the OS to the sealed down low?

I have pics of my amp in the fan mod thread and it is the 7500. It still doesn't take up all the spaces that appear to be available.

Great news on the 20a breaker. I would be super annoyed if it happened very frequently - and running a dedicated 30a (although possible) would be an epic PIA at my house.

I run mine on a 20amp breaker, dedicated line. Using 3750 watts on one channel and 2000 watts on the other channel. The only time I trip the breaker is during REW sweeps.

I did actually trip it once playing a song from a KC GTG, but I haven't been able to replicated that once.

Last night I watched Art of Flight, twice, at reference with subs 10db hot. No issues..... and that's some demanding material.

OK. Thanks. I was sure it was the 5000 model. Seems logic then that the more expensive Crest could have the additional caps and perhaps a beefier power supply. I would like to see one though.

Ture enough! biggrin.gif

But, you do have to work at it to get a 20A kick.

Hey pd can the CS 4000 be part of the buy as a option?

EDIT> or the CS4080hz

It shouldn't be a problem.

Any more questions RE: pricing on different models is going to have to wait until we are ready to go with the initial order. At that time I can make one last call about any products not yet mentioned.

Gotcha! Thanks!

We have five commitments as of now. Six if I can get Steve his model, and Steve wants to buy it.

The three below- can you please update where you are at? H8TWRK I got your PM.

JBrown - 1
Asu -1
H8TWRK - 1

I'll be sending out PMs late next week with my contact information / mailing address.

To have the payments in to the shop by the due date in the first thread people will have to send their money prior to that date. If one person is late it holds it up for everyone.

Anyone compared this to a FP clone? With warranty and 2ohm reliability these could be great for people that can run a 2ohm load per sub and even 2 drivers equaling 2ohms in some cases.

No doubt. With some favorable testing results people would be all over these.

However, I do believe the clones now do 2 ohms as well or at least according to Sanway.
post #115 of 282
I would be one of those people jumping on this, if we can get done legit tests done. I like the warranty, the brand, the efficiency, and the fact that it matches the rest of my amps, but if it doesn't get to 5hz, then the rest of my equipment was purchased for nothing. frown.gif
post #116 of 282
I'll probably jump in on an IPR 7500. Just a quick question to seal my thoughts on whether or not I want a DSP model or not.

The linkwitz-riley filter that can be applied on the IPR's DSP. Can that be used to make a rising house curve for sealed subs like the minidsp is capable of?

Agreed. We could probably get closer to the 20 mark with testing...getting the better discount.

i tested my ipr 7500 when i got it it works at rated power 1 channel at 20hz so about 3700 watts this is RMS it ran like this for about 20s if i remember correct i also tested @ 10hz it was down to 2800 watts RMS. i didn't have time or the resistors to test 2 channel operation and sadly still don't have the time to test any further.

tl:dr 1 channel 2800 watts 10hz , 3700 1 channel 20 hz, no significant roll off

How did you test it for 20 seconds at 3700 watts without the breaker blowing?

good question smile.gif b/c i didnt have a 30a breaker at my old house ill go look at my old post i didn't write anything down on my computer at the time so its somewhere on the forum.

but i do remember it clips at 2800w 10hz and i wasn't tripping the breaker after at least 10 secs.
