| How Do Digital Amplifiers Clip? This got me wondering how digital amplifiers clip and how an underpowered digital amplifier affects the speakers when over driven?a digital power amplifier is a switching amplifier (a cousin to the omni-present switch-mode power supply in our comp... | |
| mark knophler 10-03-12: PtmconsultingKnopfler has been recording and selling the same old stuff for the last 10 years, ever since he left Dire Straits. It has just been more and more of the same. No, I haven't heard this new one but I am not inclined to spend t... | |
| Life of a PS Audio PowerPlant?? 10-01-12: StevechamYes it does and, ....wow! how come your P300 was/is so different from the one I have? My P300 does not have a fan. The one that my friend has also does not have a fan. (Just as an aside: In fact, if it did, I would never have bo... | |
| Beware purepower inc To clarify for Bombaywalla, PurePower Partners LLC is a US corporation, incorporated in New Jersey. The product is manufactured in Canada. The counterfeit sales took place in Florida and thus the Florida courts are the correct venue for the lawsui... | |
| Amplifier Capacitance Amplifiers are line regulated. It means that amplifier supplied from 40V and set to produce 5V output voltage will still produce 5V output with supply lowered to 35V or increased to 45V.Kijanki, I can believe this BUT I do not think that this is d... | |
| vintage equipment repair Loose, don't waste your energy or typing time trying to convince Buconero117. Not worth your time. Let him be happy with what he has (& you be happy with what you have).Pity that he had nothing to contribute to this thread but had to blurt out... | |
| Life of a PS Audio PowerPlant?? 09-30-12: Vicks7Interesting. You defend vigorously PS Audio Units but seem determined to cast dispersions on Purepower. You are either a dealer, work for the manufacturer or have a hidden agenda. what a load of crap from you Vicks7.I'm not defendi... | |
| Beware purepower inc Vicks7, you need to take a serious chill-pill, dude! YOU are the one ranting, not me. Ok?I merely asked a question to Purepower (& I want Purepower to answer it & not some disillusioned imbecile like you) for clarification.Nowhere in my po... | |
| Life of a PS Audio PowerPlant?? The PowerPlant to which Tiofelon refers will overheat. That's the main issue with it; and with the P500, as well.This sounds like a bunch of rubbish Jburidan! The Power Plant 300 that OP is asking about has NO ' cooling circuit' that you refer to ... | |
| WHAT GOOD IS SPEAKER AND CABLE IMPEDANCE ANYWAY? Lol, Nonoise!!Rower30, good to read that you've attained enlightenment in this life-time. ;-) | |
| Beware purepower inc .....series of outrageous claims, and ignoring US court orders to cease and desist.Purepower, you are a Canadian company. So, what are the US courts doing given out rulings in your favour? Why are the Canadian courts not taking the action??? | |
| Amplifier Capacitance but once we draw less than max current, power supply voltage modulation at low frequencies becomes compensated by amplifier (since it is regulated).Kijanki, I don't understand this statement. Power amp power supplies are not regulated (I don't see... | |
| Watts up with that? ... hooked up my Wavetek digital multimeter across the speaker posts to read AC volts...I think that Almarg is on the right track in his 1st paragraph. I was about to write almost the same thing myself.Pull out the spec sheet for your Wavetek DMM ... | |
| Amplifier Capacitance If the amplifier has a -3 db point that is a frequency lower than that of the timing constant of the power supply, then the amplifier can modulate the supply, which results in IM distortion amongst other things.Ralph, let me see if understand what... | |
| Amplifier Capacitance This is why an amplifier can 'motorboat' (repeated thump) if a filter capacitor fails in the supply- the timing constant has become so high that the amplifier exhibits low frequency instability.I recently bought an NAD 2600 with a disclosed possib... |
