MUSYSIC 2 Channel Power Amplifier Distortion Free and Clear Sound - Professional 2U Chassis Rack Mount Amplifiers for DJs/Experts/Events w/ATR Technology/XLR and 1/4 Inch Inputs - 4500 Watts

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.

this is decent amplifier easy to hook up and has a good sound pretty loud for the price

This amp is good..Just right for my 2 15 inch..plus 2 12 inch 4homs..It kicks but ..Nice sound.. it's a beast with my mixer and Dj controller..5 stars from Dj Grace

Es lo que esperaba, excelente

I have 4 4500 watts I run my large PA set up with a full band with all JBL speakers they sound great and get really loud if I need to with EQs and crossovers I can get just as good sound as if they was crown amps

The rack ears do not fit! WARNING, you're going to spend over 2 hours drilling out the ears, filing metal burrs, sanding, masking and painting them and them maybe it'll fit in a standard rack but it still won't but go right ahead and try it yourself. If I had a machine shop at my house it would be possible but I don't. I loosened all my rack gear too and it still would not fit, even with slightly bending the sides of the rack inwards. Someone might say it's not a problem but it is a problem. Why should I or you have to go through all this aggravation, work and lost time. The amp install should have taken 5 minutes, that's it. BEWARE THE RACK EARS ARE NOT STANDARD SIZED FOR THE USA MARKET. UPDATE: I've decided to exchange the amp in the hope that the next one will fit. I'll update my review soon.

Lo compre para un local de 60 metros cuadrados aproximadamente, y lo conecte a dos cornetas, las cuales funcionan perfectamente, es un buen sonido ya van 6 meses desde la compra

sound is okay but the fan too loud .
