If I've got 4 x "8ohm" cabs to run from a K20.......I'll put them all on a single channel personally

Have to disagree with last 3 comments. Used a QSC PL 380 vs a Powersoft K 10, and was totally dissatisfied with the 380. As Elliott said, this company now buys into the Behringer type wattage specs. and it shows.
As far as I am concerned, QSC has no real heritage in reliable very high power amplifiers, compared to crown, Lab Gruppen and Powersoft.

I have no experience with the K10 but a lot of what you are saying about the pl380 is objectively wrong. The PL380 exceeds its specs, putting out over 2900 watts at 4 ohm @ 40hz before clip while stating 2500 in its spec sheet. https://www.abeltronics.co.uk/amptesting/amp-meet-three.php . The pl380 not some new amp that has a questionable reliability and power output. It has existed for more than 10 years, people have a lot of experience with it; it almost has a heritage of its own. This ignores the fact that the PL9.0, RMX5050 and mx3000a exist.
I cant comment on your personal experience using it, but I guess sound is subjective. Edited by citizensc - 19 November 2019 at 2:08am |

The problem is likely this constant fixation on watts. Yes, an amp needs to be able to supply sufficient current to handle the number of cycles asked of it, but much more important is voltage swing and efficiency. Music is dynamic, we aren’t cooking food in a microwave or trying to light a room with a filament here. |

Powersoft K10 is better in every aspects than PL380.

Forget them all, and get a LAB PLM. Works every time. Or FP if you dont like having your DSP in the amp.
They walk All over everything, so its a good investment. End of discussion :)

How still they get bipolar power Si-transistors since no company making them anymore? Does it have the usual LabGruppen's Switching Buck pre-regulator followed by a linear Class AB stage for signal smoothing, right?

I really dont care whats inside. They turn on every time i ask them to do so, and they never fail. Loads of power and control. Really good sound regardless of what you hook them up with.

"How still they get bipolar power Si-transistors since no company making them anymore?" What? That´s an absurd statement! Of course they are. Here are a few high power devices:- No shortage there. Edited by Earplug - 19 November 2019 at 6:14pm |

I've been on this forum for far, far too long, and it's only in the last couple years that I've really started to see whose posts you can actually take with a very large pinch of salt |

QSC make good amplifiers however, you need to understand what the general public wants. That has always been the concept of QSC. They were the first manufacture to revolutionise our industry offering lightweight (Powerlight & PLX) amplifiers. Their amplifiers were also very tolerant when faced with low voltage which, is essential in parts of the world where voltage is very dodgy.
This is the most important thing that many of us tend to forget about amplifier manufactures. Their main objective is to attain the specified wattage with the lowest distortion possible. So, as technology moves forward, the distortion will be reduced from the previous models based on new innovative parts. For Mid to High frequencies this may be all in favour however, for bass it may not be wanted by some.
I recall a Crown Representative stated a decade ago after numerous complaints about the I tech 8000 not sounding as “Warm” (I know poor choice of words) as the MA 5000vz on a forum to just load the Itech down until it sounds like the Crown 5000vz. Although, a lot of users were not happy with the answer, there was some truth in his reply. The Itech had no parts of the Macro-Tech other than a logo stating “Crown.” The same thing applies to the QSC Powerlight 3 compared to the Powerlight.
The market today is powered speakers. Don't be surprise within a 10 year period many of these brands we tend to debate about merge with a loudspeaker manufacture and do away with their stand alone amplifiers altogether. Remember we are hitting a new decade and, a lot of things are going change in our market whether we like it or not.

Recently went to amp/driver test, and one thing I learned, bench testing amps with purely resistive load, proves nothing. Edited by levyte357- - 26 August 2020 at 5:23pm |
