Not sure if this works with inuke3000 ...

That wont work for me because I only have a single connection for a single voice coil on my sub. So it will always be 4 ohms, I dont think it can handle 2100 watts..

No that's too much power. There is a limiter on the inuke3000dsp. If you set it to 50% then that might work. Need someone else to chime in

Oh I didnt know there was a power limiter in the inuke. Ill have to look for that.

i just looked at mine and it limits in dbs, not percent. Not sure how it works.

Oh, your talking about lowering the gain in filter/crossover? It only lowers by 12dB, not sure if thats enough to compensate for 2100 watts or how it would sound

Ltd needs to mosey on over here and educate me!

You set Load to 4 ohm and move the peak limiter "dial" until the value in Watts is where you want to limit to...

I'm sure they will get here sooner or later.

I never heard anything either but I got an email from FedEx eariler this week and they arrived today. Hope you get them. I have never had anything like this and now I have 2!!!! My buddy and I will start the builds soon. I will post more in the Marty flat pack thread!

When using the peak limiter on the inuke how do I tell what rms I'm running?

Connect your remote software to your iNuke...under configuration, select your mode. Click the little up arrow in the LOAD box and select 4 ohm. The software will display the available watts for the configuration mode selected and the impedance setting of 4 ohm. Now "turn" the limiter dial until the value displayed in WATTS is the max you want to send to your driver...smile.gif

I work with a lot of professional amplifiers that have built-in DSP. The behringer DSP is actually pretty nice for the money and is super simple and effective

That's what I will do, but if the peak is to 1500 watts is there a way to know how many watts I'm sending rms since it's a peak limiter? I just want to be sure I'm not maxing my driver which is 900 rms 1500 peak.

That is a good question and one i would like to see answered as I also have a hard time figuring out exactly how the limiter works and how it differs from other similar function like the dynamic EQ. Say.. If you set it to 4 ohm and dial in 100 Watts can you then deliver 99 watts indefinitely into a 4 ohm load?

I have used 70% of peak number from Behringer to calculate the continuous watts...this is what I have seen used around this and other forums but I am not 100% certain. So in your case, it would be 1050 watts...

1100 watts is the continuous power that is perfect for that driver. I know that for certain .

I haven't done any of this on my 3000DSP, is this something I really need to do? My SI 18 D4 is wired for 2 ohms and am running the amp in stereo.

I helped a friend set-up his iNuke 6000DSP with two 18" subs on one channel and a single Buttkicker Mini LFE on the other channel and used the limiter with -10dB setting (IIRC)...I then tested demanding LFE movies and while watching the remote software could see the limiter in action. My friend was happy with the impact from the BK so I stayed with the -10dB setting on the limiter.

That is around the same number as AlphaPie...should be fine. I have two SI wired for 4 ohm off a bridged EP-4000 - should be around 1000 watts each and have had no problems.

Im going to take your word for it set limiter at 1500 which should net me close to 1050-1100 rms even though my sub claims 900 max rms. Hope it doesn't melt biggrin.gif

It will be fine. Now tell us the good news about the increase in power.

If you set it to 4 ohm and 1500 watt, does it then show ~77.5 volt in "vp" ?

This is the closest I could get to 1500 on the dail, its 109.9 vp

post #895 of 999
OK thanks.

In that case the "watt setting" must be rms and vp is peak voltage, because 109.9 peak volts equal 77.7 Volt rms and 77.7 volt rms into 4 ohm equal 1510 watt.

You divide peak voltage with sqrt(2) to get to rms voltage and (rms voltage)^2/R equals the power in watt.
post #896 of 999
appears that is actually measuring the top of sine wave as the "peak" voltage. in this case 109.9v.

the rms voltage at that level is 0.707 * 109.9, or 77.7v.

power is calculated off rms voltage as e^2/r. 77.7^2 / 4 = 6037/4 = 1509 watts.

try to stay away from sine waves on/around the tuning frequency with that power.

edit: looks like we were typing at the same time. :-)
post #897 of 999
also, when it says 1500 watts, that's not completely accurate.

it would be if the driver were just a pure resistor at 4 ohms, but in an actual enclosure, the impedance swings up and down depending the port tune and the driver's resonance.

here is the impedance, in a martycube for example:



and the actual power, with a "1500 watts" setting:



the power peaks around the tuning frequency of the sub. is lowest at where the impedance peak is at its highest (which is the resonant frequency of the driver in the cab). and then is limited again on the top end by the low pass filter that most folks would use (in this example, i put a 4th order low pass at 80hz on there, which again, is what most folks use or at least start around).

And do you think raising the wattage will help me stay out of the limiter led on the inuke? because right now running stereo I hit it for several seconds at a time. So with doubling the watts in bridge mode I should be able to turn down the knob on the front and gain output at the same time?
post #899 of 999
I'm a little confused about your setup Alpha. Are you running a 3000dsp in stereo mode into one 4 ohm woofer? If you only have one 4 ohm woofer and a 3000dsp then you should definitely run in bridge mode. In stereo mode you only get ~600 watts, but you could get 2 x 600 watt if you had two 4 ohm woofers.

Yes I'm running in stereo mode at the moment to one woofer with a single void coil.
