Customer ratings for McGrey PA-4502 Power Amplifier 1U 2 x 450 Watt

As far as I can tell, the power amplifier delivers its power per channel; I will measure this again. Everything you need for stereo. Okay, the frequency range could be a little better, as the power amplifier reproduces 35 to 20,000 Hz at -3 dB and 27 to 20,000 Hz at -6 dB.I suspect that the 20-20,000 Hz is then at -10 dB, but unfortunately that's not in the manual. And the fan has a whistling noise that can be eliminated by installing a different fan, so please work on the fan. But otherwise, this is one of the cheapest power amplifiers I've found that really delivers on performance, and I can recommend it.What I also really like is that the power amplifier has 450 watts RMS at 2.4 and 8 ohms, as it is actually an 8-ohm power amplifier that is also stable down to 2 ohms and, due to power supply limitation, cannot deliver more than 450 watts regardless of the impedance, which I think is very good. All manufacturers should do this.

First of all, I have to say that I was simply looking for an extremely affordable power amplifier. What I like is the weight and size, which means that the controls are also small, but that doesn't bother me because I don't fiddle with them anyway :) When switching it on and off, you can hardly hear anything—no banging or other noises, which is very pleasant. The fan is very quiet!
The sound is clean and good. The bass range is great. Of course, I haven't tested the little power amplifier over an entire evening yet, but so far I'm very satisfied.
So far, it has powered my speakers and bass well, so I would say it's not a rip-off. It's not like it only delivers 2x 150 watts, which you would think at that price. It delivers! I'll continue to test it, but for now I'm very satisfied. So don't be put off :)!
