Is that one of their plate amps? The Pascal amp modules in them have impressive specs.

The price is a bit painful considering I've already got enough DSP. I wonder if they'd sell them without the DSP/Network stuff.

My inuke 3000 dsp was delivered today but I can't test it out yet because I don't have any speakon to speakon cables. lame. Figured I still had some more time to find a good deal on some 12 gauge cables.
post #34 of 182
So silly questions but im planning on getting the inuke300dsp. But the speakon thing is all new to me. For receiver to the amp itself do you just use a normal rca to 1/4 TRS cable for input? Then for output a 4 pole speakon cable? Then just have a 4 pole connector at the sub? Then just hook up the sub wiring positive cable to 1+ and negative to 1-?

For the receiver to amp they have male RCA to male XLR from monoprice but RCA to 1/4 trs will work too.

For speakon connectors I have no idea the best route and would be interested to hear what is considered the best solution.

avr to amp =
RCA to 1/4 TRS, or RCA to XLR -- monoprice sells the second cable cheaply

amp to speakers =
There is only speakon type outputs on the inuke dps 3000 amp, so buy a speakon to whatever kind of connection your sub needs. You don't need four pole speakon connectors, just two pole. If you already have four pole speakon connectors you can use them, but two pole speakon cables are cheaper.

Here's a thread with some good price ideas for the cables you'll need.

If you just need regular raw speaker wire on one side and speakon on the other and it's for a short run these might prove to be your huckleberry.

Just keep wire guage to length requirements in mind
http://www.roger-russell.com/wire/wire.htm#wiretable

That particular seismic audio cable for instance is 16 guage wire. For 16 guage wire you should have a maximum distance of
12 foot for 2 ohm
24 foot for 4 ohm
48 foot for 8 ohm

Since my subs are two ohm, and my distance is about 25 foot from sub to amp in my room, I need a 12 guage wire. My subs use speakon connectors too, so I'm either looking to buy one of these cables, currently out of stock, or make my own.

I dont understand. They released already all Inukes Models for USA; including DSP Models; EXCEPT 6000 DSP MODEL !!!!!!!!!!!!!!!!!

Expect release date NOVEMBER 25th! WTF!!!... (within 75 days). Now I have to wait that LONG Test my sub!!!!!!!.....

I was thinking in buying the 1000 DSP Model and then returned it to get the 6000 DSP Model; but American Musical Supply gives 45 days money back guarantee!...

@Archaea - Did you got the Speakon cables? I want to hear your impressions of your 3000DSP amp!....
Isnt there any Inuke 1000 DSP/3000 DSP for rent for 75 days?!

Or I can buy the 3000 DSP Model and sell it later for like $350 with free shipping.
post #38 of 182
That could be tricky now. My second daughter was just born pre-maturely by 1.5 months - so I've been at the hospital all week. I don't know how/when I'll have a chance to crank the tunes anytime soon since my new daughter will not be able to leave the house...I'll likely be able to test the DSP functionality at lower volumes.

My speakon cables haven't arrived yet.
post #39 of 182
Ok ok. God bless your baby!... Family is first!... Take it easy. I'm going to buy the 3000 DSP Model; and then sell it later.. I CAN'T WAIT!!
post #40 of 182
i ordered all the stuff for mine (speakon cables and the such). The actual amp doesnt come till Wednesday though. So looks like next sat or sun before i really get to see it (its actually my dads)

Just get the one without dsp and buy an eq later on down the line if you need it.
post #42 of 182
I just made a set of speakon cables out of a 14 guage speaker wire I had with the correct connectors to give it a shot and make sure everything worked on the 3000 DSP. I hooked up my pair of 2 ohm Captivator Pros one on each channel for a stereo 2 ohm load.

Initial impressions

1) The Inuke DSP 3000 has plenty of power. It's loud enough with 2 of 4 meter lights blinking...The EP4000 doesn't have meter lights for me to compare with.
2) The fan is absurdly loud when you start approaching reference volumes! it spins like a Georgia swamp air boat!
3) The DSP can be manipulated or at least viewed (I didn't try to change anything) showing level meters and such while playing back, through USB. It's kinda cool to scroll through the setup with the USB connection while playing back music.
4) The orange color is pretty lame - orange doesn't go with anything on my equipment rack. It's fine for a DJ rack, but it's bright and it's orange -- not exactly a sexy color for an equipment rack. I don't really mind that much, but would prefer they used a more traditional red, blue, or green.
5) The power usage ---doesn't make any sense to me watching the amp gauge's output numbers on my Monster Power HTS 5100 MKII. With the EP4000 at -10 from reference I'm seeing 5 or 6 + amps routeinly (average) on the amp outbound socket's average. On this inuke amp I'm seeing 2 or 3 amps or so --- volume is about the same to my ears!!! I don't understand this high efficiency switching electronics --- how can you save that much power?

Luke Kamp and I will hopefully get a chance to measure it sometime with his omnimic, but first impressions are actually good.

The fan is just silly. It doesn't bother me at typical volumes - even in stock configuration, but it ramps up and down fast. It'll go to crazy hurricane mode if you push the amp hard, though it doesn't stay in crazy ramped up spin mode very long at all after letting off the volume, but when the fans is ramped up it's definately an inappropriate volume for a home theatre.

Excellent!... I already ordered the 3000 Model; Lets hope I can get it by next week. Keep learning from it so you can teach us! How do you set into bridge mode?

I still stand by this statement, the ratings that behringer put out you can pretty much cut in half.

+1

I've posted the same caveats on the power ratings. Kinda a given, no biggie @3db.

I just hope they have robust single digit extension profile, for those of us so inclined

About 20 posts back I linked the independent tests for the 2500 as well as the owners manual and they were in close alignment.

Congrats on the amps arrival, I'd like to know more.

I'd not recommend changing it out, instead, try building some type of hush box or equivalent. Perhaps over time some safe fan change outs/mods will appear, but I'm not much on fan mods anyway. Many enthusiasts feel differently however.

Can you monitor line voltage, and PS temp?

I believe it's class D amplification. In theory, the efficiency of class D amp is 100% Ideally, none of the power is expended as heat, all of the power throughput the amp, should be delivered to the load. These output devices either conduct, or they're open,..so no heat is dissipated. However, obviously there is heat issues, so some leakage current, or something is conducting at less than the theoretical ideal short, or open state.

In my opinion, unless they're incredibly robust and over sized, I'd never feed an amplifier through a power conditioner/surge protector. They don't need them, and they can do harm in dynamics limiting via voltage drop/current limiting. YMMV



Thanks for the updates

Regarding amps, I defer to you.

I'm merely saying I'd be suspect, and I'd halve their ratings. Additionally, as I pointed out, that's only 3dbW, so no biggie either way.

Hey, I'm a fan of the ubiquitous EP4k, I own multiple...but 4k it ain't. But,..again that's only 3dbW. For HT, they're great. Besides, in my experience,.. running them on the ragged edge can create some weird, unpredictable behavior at clipping onset, so I'd watch the clipping. Seeing the EP4k/2.5K everywhere,...I liken it to the DH500 or Carver's 1.5, seems like in the circles I ran in, everyone used to have one. Similar to Dynaco before them I'd guess.

Thanks

I don't use bridge mode, because I run two 2 ohm subs on stereo, or dual mono mode in this case, but the amp itself couldn't be easier to setup. The setup is all done through the GUI, and it's picture and graphic based, so if you want bridged mode you just click with the mouse on the option you want. The interface is actually VERY good! When you make a change to ANY of the DSP settings, it reflects what that change will do on the FR graphs. So If you don't know what a butterworth filter does as opposed to the other optional filters, - the GUI will update to show what your FR should do with this filter. Download the software from Behringer's site and play with it to see what I mean, even without the AMP hooked up you can see most of the functionality - you just won't have the level meters being active.

I'm not sure how truthful the amp's ratings are, but it seems pretty powerful at my initial demo session. The manual speaks to 2x1500 watts at peak 2ohm stereo load, and 2x1100 watts at RMS 2 ohm stereo load. The amp seems quite capable in my room, just like the EP4000 is.

I'm going to play with it some more, to see if I can tolerate the stock fan in normal mode, which I think I can. When it's in the A/V rack and the fan is facing the back, it's not too obnoxious at normal speeds. It'll just depend on how often and on what occassion it rips into outrageous mode, which I won't be able to tolerate. What kind of "hush box" are you talking about? How do you keep a hush box cool inside?

I don't think I saw a field for line voltage or for temp, but there is a active level meter showing 0 at the top and db's going down to -60. This is another good reason to check out the software download so you can see for yourself what options the DSP provides. It is a small download and you can open it up to clearly see its functionality - even without connecting it.

Here is the inuke dsp software link again for those curious.

But it's only half. I'm sure anyone who took delivery of their new Vette ZR1 would be happy for it to only have 300bhp and still pay full retail.

Thread Starter 
Took the amp apart to put in a new fan. Lucky for us, the fan is 12v, so I had a quiet one laying around. The stock fan is 12v .4a and the replacement 12v .14a. It is MUCH quieter, almost slient. I cranked the amp a bit and didnt have any issues with protection mode coming on so I think it will work with a quieter fan, but YMMV.

No doubt

but I think a better question might be...is anyone buying the LMS5400, okay with 2000Watts instead of 4000Watts?

I had all intentions of running my Funky Waves LMS with a 4000w Crest 8002, but it was out on loan to a friend, so I was using a EP2500 in the mean time. I have not replaced that amp - Its more then I need for my small room.

My buddy that was borrowing my 8002, got a pair of EP4000's for his LMS's in his 6000^3 room. He's more then thrilled with the output - he doesn't push them really hard, so its fine, but he's still got plenty for his needs.

This new Behringer Inuke Software needs to be ported to Ipad!!

Inuke 3000 DSP Arrived Today!... But I am workinggggggggg!! Have to wait until 12 midnight to get it!!

@Archaea. Can you send me your .arp file to see how you setup your frequencies, peq, etc? PM you.
post #56 of 182
I've not played with anything that I've saved or kept yet and haven't got to do any measurements yet. My file/config would only be good for my room anyway because I've got a NASTY dip at 50hz -in my room with every sub I've tested as evidenced by the subwoofer meet frequency response graphs. your room and thus config would be different. Ive just played with the settings and then reset to default at low volumes so far.

So I'm no good for you there. My newborn baby is still less than a week out of the hospital and I've not had any chance to really tool around with the amp yet. I'm sorry man.
post #57 of 182
HELP!!!!! HELP!!!!! HELP!!!!!

I got the Inuke 3000 DSP and I dont know why my sub sounds extremedly soft. I raised volume to max in the amp, I raised sub levels in my receiver to max, I also add +12 gain on the amp and it just lights the first led level on the front panel on the inuke.

I touch the driver and yes is barely moving. What could be wrong? A faulty driver?, Speakon cable?, the XLR to RCA cable? Im so frustrated; spent all this money and hard work for this sh!t!!!.?

The Speakon cable has 4 connectors (+1, -1, +2, -2). The wiring is the red cable connected in +1 and the black in -1. Could be this the problem?

The XLR cable I am using is a Male XLR to Male RCA. So its connected from inuke to sub out on the receiver.
My PL200 sub sounds way way louder than this and its a cheapo $269 sub.
post #58 of 182
Is your sub in a box or free air? What receiver are you using? Some receivers need a device to boost signals to allow consumer receivers to properly put out pro level voltage for pro amps. Examples of these devices are like a Samson sconvert or a art cleanbox. Yamaha receivers are an example of needing one of these boxes. It is not your speakon cable or amp most likely. If your sub isn't in its box yet that explains everything. What sub? What box? What receiver? What amp mode?

I have no idea what means if the sub is in a box or free air. My receiver is a Denon 3311CI. Amp mode? Is that stereo, dual, bridge, etc? If so I tried all and got same problem.

I will take pics of the sub, connections, etc so you can tell me If there is anything wrong.
post #60 of 182
He is asking if you are just testing the driver alone or do you have a box built already.

Also, the Denon "sub pre out" should have enough voltage to driver the 3000 to clipping.

FWIW, I had the exact some "WTF" moment with my first subwoofer design. I installed my IB array (4 x 18" woofers), connected everything (EP2500 to a pioneer AVR), turned it on and was extremely disappointed Not matter what volume level, Trim settings +12, LFE setting +10, etc. I couldn't get output. I bought the Art Cleanbox and that solved my issue but the ART Cleanbox has a SSF @ 18Hz (No good for 10Hz performance requirements) so I found a Samson S-convert which didnt have any SSF.

Sometimes there is a requirement to increase the voltage going into the amp. Before you buy something though, check all dip switches, check cables, etc.
