well craigs is 59hz mine is 73hz. if you think the parts in that amp are capable of that kind of power it should sale better than anything ever made, and revolutionize the entire amp business. i'm sure all of the concert pa people would be interested to so that they can quit carrying 75lbs amps and switch to your 15lbs amp. by the way i use a fluke rms multimeter, and amprobe clamp meter.

In fact PA people already swapin their heavy-weight amps for things like that: http://www.k-series.it K-20 model is about 2x 9k/2 and 18k/4 RMS in full range, with damping factor over 5000, and thats the most powerfull and the best amplifier on the planet - PA people says that, not me Output voltage is up to 220V and current up to 102A. This amps got active PFC which can manage >0.95 in full power - that mean that is realy PRO amp.
All about 26.5 lbs.

i've never seen a k series amp running turbo sound, avalon, eaw, or any other high end pro rig. but maybe as people care less about quality and more about volume things will change.

WOW... I am sure this amps can do 0,5ohms.... SO.....! 20kw @ 2.5ohms 40kw @1.25ohms and so on...... Crazy.
You are quite a funny guy Chris.
The amplifier work at 1 ohm, not 0.5.
The power supply have a voltage drop on heavier loads, so the voltage the amp supply to the load (as a constant voltage device) decrease as the current increase.

The diff might be on the amprobe clamp.
Actually we are developing D class PA amps, with PFC SMPS power supply. Well, We really think we already have a revolutionary desing on car audio amplifiers, just check the size of our amps.
If you use a normal transformers, with iron nucleous, the weight would be at least 10 times higher, but nowadays there is no need for that anymore.
Check this 8000W D class PA amp, from Crown. Wheights 28 lbs.
It is light because it use a SMPS power supply, this is the future. Back in days the designs were very poor and the PA customers used to think a SMPS would not be trustfull, but nowadays all changed.

Oh you have an even better example!
When we have first units running Ill send info, we plan to enter in high-power range of amps..

What about lab gruppen? You ever hear of that company? Got rid of racks of crown macrotechs to run the labs and it saved our backs. Also have them running turbosound and eaw rigs. No problem.

The amplifier doenst store energy, it transfers from the battery bank to the load (speakers). The capacitor bank works as a filter to eliminate the ripple created on the power supply switching.
We are so confident about the performance of the SD12kD because of some points listed below:
1- It has a 250V power supply, PWM (as all SounDigital amplifiers, allows the amp to operate from 8V to 18V and to deliver high power at lower voltage too).
2- This 250V power supply feeds a H-bridge output stage, this is the main reason for the extremely high power, using a H-bridge we can deliver the double voltage on the load that a half-bridge would do. So to be comparable to a SD12kD a half-bridge amp (like the ones made in Asia) would require 500V on power supply, and there is no such a amp on the market.
3- A recorded microprocessor controlled, inside it runs at 20Mhz our control program, controlling from the power supply to the output stage, WAY better than using old power supply controllers (I'm trying to not point, but 95% of the amps uses them)
The thing is, we took 2 years developing this high-voltage and high-current (since it works at 1 ohm) amplifier, it is our master piece, and some other amplifiers are trying to beat us on the LABEL, but they wont on the POWER and reliability (5 years of warranty). All the power electronics needed to change, since we moved from the 200V max circuitry to a higher level. SD12kD as far as I know is the only one FULL bridge 250V amplifier on the market.

Murilo I think he is asking how he can daily drive this amp pulling 1000-1500 amps DC through two 1/0 cables.
Well the short answer is NEVER run the amp on one battery daily and never let the power wire runs exceed 18" in length(so have a 600-1000Ah bank of batteries near the amp). The wires may still get warm with the current but maybe after some time playing full out. Make sure connections to the block are solid so it shows less resistance at higher loads too.
Hope that helps.

Also remember that music have a high crest factor, normally around 10dB at max volume, so actually the medium current flowing through the inputs will be the max current divided by the medium crest factor of the music.
Those good bass race songs will be lower than 10dB but not too much.

Is it mean that we can get continous 50k on 2x 1/0 ?? :]
Murilo my dear H bridge is nothing new... am I wrong ?? Every bridgable amplifier is usin this "technology" U just did the same thing which for eg. Maxxsonics did in their XX Maxximus, but on one pcb. I know Yr product is "a bit" diff. but it mean the same. If U'll bridge two any "Half bridge" amps (any bridgable mono, usualy most of) than U'll get "H" isnt it ??
And yes U'r right with voltage with Half b. and Full b. but that's SOOO obvious

Sure U can but on very short distance... every singe " is matter with that current.

keep the 2+ and 2- runs very short and you're fine. Obviously you'll want more runs from the upfront charging system, and for daily you'll want more batteries. You just need more wire run to distribution.

Hello Mark,
50kW? Sure, on a very short distance.
And you are right, H-bridge is a very old output tophology.

How long will This Amp stay on At F/T before it kicks Into Protection From Heating issues It has to get very hot Trying to Make all this power...
Hmmm... It just kinda Scares me Like Stetsom...
They do power But Gotta Jimmy rig them To do so lol
Bro I dont know if your just trying to give SD negative publicity but give it a rest. The amp makes huge power and if you use it like you are supposed to with a bank of batteries you can use it for daily like most other big amps and you dont have to have the amp modded for daily use. From your posts its obvious that you dont know enough about amps to actually question Murilo about his product. EVERYONE that has a 12k is more than happy with it and I have personally seen the 8k in action and was more than impressed. Stop worrying about numbers and talk to people that have the product and see what they say. Murilo has posted power tests and so have a few others and in all the tests the amp makes the rated power and much more so give it a break!

lol wow why dont you just try the amp i bet you will be more then happy with it i know the amp is the real deal. one battery 154.1 with one 8k car off one battery 2 12`s street b. not to impresave but sure is loud for what i have.
I know guys that will back me on this in a test on 16volts they have seen 14k out of just one 8k at 1.7 ohm with rise. so dont knock somthing till ya try it cause i know you will be the next one saying holly smokes this is one bad azz amp lol trust me if you know what your doing and have any clue at all you will say what i just stated. They are one bad azz lil amp.
