KINT - Ecler GPA2-400 vs eHSA2-250

Today I'm comparing two ECLER amplifiers, one of which I've already shown and discussed in detail:    • Ecler GPA2-400, czyli ile można się cenić   I think this is quite an interesting comparison, as we can observe the evolution of amplifier designs from the same manufacturer. As I mentioned in the video, installation technology isn't my specialty, but it's becoming increasingly important in the market, to the point that some well-known manufacturers (like QSC) are abandoning their "stage" business in favor of this type of equipment. Just as I did when presenting the first amplifier, I'm also considering the cost of purchasing such equipment, because it's undeniable that ECLER isn't exactly a budget-friendly company, regardless of the type of equipment they offer. But since they celebrated their 60th anniversary last year and are doing well, seemingly without the involvement of outside capital, they're clearly finding customers and may they fare well, because from a purely technical perspective, these products are hard to fault. Finally, I'll add, as a curiosity, that the output section in the e-HSA2-250 amplifier operates in a Class D bridge configuration, as pointed out by one of my viewers. In this case, we have four separate amplifiers, connected in pairs in a bridge configuration. All of my company's output stages had the same configuration, which you can read about on the company website, for example here: https://pmpproaudio.pl/o-firmie/histo... You just have to scroll almost to the bottom of the tab. I would like to draw your attention to the fact that I have recently posted on the website scanned "printed" instructions for several PMP tips, the last pieces of which were delivered to customers over 20 years ago, and many of them, including much older ones, are still in use.
