- Professional Power Amplifier 2 Channel 2000W - Home Audio Component Amplifiers for DJ, PA System, Speakers - high Quality Stereo Amp with Digital Audio Processing - Stereo XLR & 1/4" Inputs

I have owned this for a few months now and I have no regrets about buying it but I found that it needs a hotter signal to get it to the wattage point so I added a nobsound direct e6 tube preamps which I personally use in my home theater setup because the class d amps need more analog input to give them a warm sound and not so harsh on the higher frequencies and midrange frequencies are a lot better imho so I use them in my entire system all 9.1.4 so I don’t use my Denon AVR amps at all and the sys 4500 fit my old school DCM tf350s speakers very well because they are a 88db speakers and they need power and the amp fits the need and with a good amount of power left to boot. I am not sure how much power they are using but I am not able to get the amp pass 12 o’clock and at reference volume I can’t listen to them at this volume very long. I bought this amplifier because my speakers were starving for power and boy it definitely feeds them and I wasn’t expecting this Musysic SYS 4500 to work as well as it does but it works . I don’t know if I got the better built amplifier or what but it works great. The tube preamps definitely help with the sound and I’m sure it wouldn’t be able to produce the same sound without them. My room is a partly open concept but I haven’t been able to get the sound that I wanted until now so I’m pleased with the amp and I thought I would hate the blue led lights but I never seen them light up other than the time I set it up and so far it’s been light free even at high impact moments. My speakers are around 28 to 35 hz which is the other reason I why I bought the amplifier because of its ability to reach high 50k according to the specs weather that is true or false I don’t know , what I do know is that my speakers are now awake and that’s what I have been searching for. Overall it is a very good amplifier and I have no complaints except the fans are a little loud and I may replace them if my rack stays in the room which I have been working on moving it to my garage. Finally thought about the amplifier i know that having a dedicated outlet would be a great idea and it wouldn’t have to suffer from lack of power , so buy one and you are not happy with it then you can return it. BIG PLUS in my book even though it’s not perfect.

I bought this to use with my keyboard setup. I was using a self powered speaker but decided I wanted to go stereo. The speaker I was using is a discontinued item and I couldn’t find another one like it so I decided to used my passive Kustom speakers with an amp. Of course it doesn’t put out 4500 watts and anyone who expects that has unrealistic expectations. An amplifier that puts out 4500 watts would be unusable in your home as it would be constantly tripping breakers. Realistically it puts out about 550 watts RMS (275 watts per channel) at 8 ohms which is all the power I’ll ever need. Of course if you need more power it can be used at 4 or even 2 ohms. But if I don’t need that much power I don’t see the point in working my amp that hard. The fans are a little loud, but if they will keep my amp running cool I can live with that. The sound quality is excellent without any humming or buzzing. I would definitely recommend this to a friend.

I was a little skeptical at first when a church i was doing an install in wanted this amp. This thing works great! Just be sure to stay with in the ratings and you'll be fine. You should NEVER run any amplifier at max power. READ THE MANUAL!!!!

Excellent product

Very clear crisp sound. Plenty of power for my church’s sanctuary speakers (we can seat 100 plus people easy). The cooling fan is quite loud but not a problem for our situation. Our internal power amp on the audio mixer finally died and this one was a great replacement (external of course). I personally feel it’s worth my recommendation.

Only makes ~250w x2ch @2ohms I put this amp on my AD-1 Amp Dyno as it was highly recommended by an associate of mine. However, we were both disappointed and the amp only made ~250w per channel at its best. Nowhere near 2000w, and 4500w would take a lightning strike.

I have this powering 2 18” Lanzars. It surprises me for the price how good it sounds.

La compre y salió bueno suena genial 😁

Wast prodat

The amplifier sounded reel good but the fan is very noisy when no music or sound is playing. If a more quiet fan would be replaced in the amp I would purchase the item again
