the output (ch1) shows a very dirty waveform. could be caused by power supply ripple or the amp itself. i saw some other videos testing the said amp and output was clean so, i don't know why yours was so dirty. don't run the amp at clipping for too long even during testing. learn how to trigger the scope properly like using ch3 as trigger source since it's cleaner.

Sbagli completatmente la formula per il calcolo dei watt RMS. La formula è: [(Vpp x Vpp):ohm]:8

Im in dought I have 75volt dc. Its work or not? Am i connect this dc source? Please ans me sir

@joelkine 6 ай бұрын

manufacturers of this budget-meal class d amplifier don't recommend using dc supply more than +/-70Vdc. so my answer is no. don't use your 75vdc supply

I bought this circuit, but the speaker does not sound, what should I do now?

@joelkine 6 ай бұрын

if you have low DC voltage below +/-44Vdc, it won't work, then if your power supply exceeds +/-70Vdc, the module might get burnt, but still depends on manufacturer. There are some manufacturers use low quality output mosfets or sometimes fake mosfets that could not withstand higher dc voltage.

RMS Output power: 1000W Peak Power:1500W What do you think about the power supply? +-70 volt power supply 1000 watts maximum power times 1500 watts would 2 boards of 600 RMS withstand 4 oms. I have another model of amplifiers 2х350 oms 2x600 4 oms. Without adding additional capacitorsWithout adding additional capacitors.

yang amp mo ba sir ay ung meron din relay? Monitor mo voltage ng smps nyo while testing the amplifier, may natest ako before na tumataas ang dc voltage ng smps pag lumalakas ang volume level, then magpoprotect ang amp, pero bumabalik ulit ang sound if bumaba ulit sa +/- 65Vdc

i think that you need an inductive load to test this thing properly ...

@joelkine Жыл бұрын

Lohi I’m not an expert, but using an inductive load, its inductive impedance will distort the measurement. Resistive load is essential in taking an accurate amplifier parameters as power, s-n ratio, frequency response, etc.

? I don’t understand why all these “DJ’s “ all perform the same type of test, they grab their cell phone and turn up the head amp to show everyone that it can generate some volume. LOL, how about you show us real world testing with a live band in a live environment, pushing 4, or 8, he’ll even ,12 subwoofer cabinets with these so-called “Lab gruppen” amps. I am yet to see anybody put real world application, life production events with these clone amplifiers. Until then, I’ll keep my original factory lab fp7000 amps.
