I do this to test motors as well.
doesnt explain why at 3% gain to max gain there was only a 9 volt difference. However when you have subs hooked up, THERES a major AUDIBLE difference as you go up. Definitely not 9 volts

Its probably not the actual outputs being limited. The input section might be to blame..
30^2 is 900
39^2 1520
Plus its averaging so 60 and 78
3600
6084 respectively
Honestly its a guess. Id really have to get my hands on it.

3600 watts only and its way louder than 8281 watts on the ampere? Yeah dude its wierd as fk.

Double the voltage. Then square it multiply by id probably use .8 since its low frequency

You welcome. Problem solved.
But in short you need to know duty cycle and the peak voltage of the dc pulse. Its easier and more accurate because you have much more time when the voltage peaks its drastically reduces the sampling rate..square wave has a much longer peak voltage to sample from..

The brizillians use pwm outputs while zenon uses a modified sinewave.
I told fucktards that last year over on www.caraudio Classifieds.com
Watch me find the thread and you can confirm i was again correct. Lol

I can show you how with almost any dmm and its better to use tge peak function and calculate rms because of the nature of the output waveform..

Use a TL Magnum in split screen, with two sets of amp probes and clamps. It reads the output voltage also. You should be up around 135vac+ ...

Since the pulses are 180degrees out of phase at peak as long as you use the peakhold function you should be pretty accurate.. im gonna look at how they get a "contunious" figure after all contunious means the rise/fall of the sine wave is linear in fashion and can be calculated easly.when you account for lag/lead.
This is more realiant on modulation and duty cycle.

The gain in voltage and duty cycle is proportional to output.
In other words voltage has little change but the duty cycle decreases while increasing the switching speed instead of peak voltage.
The meter won't read the negetivity charged pulse because its an inverse flow of current so they basically absorb each other.

phase shifts as outlput increases from higher switching speed to use the mean rating and the higher sample rate. Which prbably went for 500hz to 5khz so even though you had a substantual gain in voltage the meter couldnt measure it because the switching speed was way to high.
Escentually it was starting to cancel out in the meters eyes. Lol.

Remember the thread over on ca? Proof i was right and i NEVER TOUCHED THE AMP I KNOW THEY OUTPUT TOPOLOGLY WITHOUT EVER TESTING ONE.

thats nice but i'm not gonna drop that much money just so i can "set my gains" when its already at a level i'm fine with. I'd rather put that money towards electrical where it actually matters.

Did you say you needed some compacators?
