MUSYSIC Professional amp 4000W Hybrid Amplifier – 3U Digital Output Display Pre-Amplifier/Receiver with Multiple INPUTs Bluetooth AM/FM Tuner USB/SD Slot MP3/Concerts and Functions MU-H4000BT

Great amp very powerful, not to mention the price, fan noise is normal, can barely hear it, i will defenitely buy again, wich am planing to, i been using it for about 4 months now, with no issues. Overall great product, i recomend ! !

so i just recieved this today i have it all hooked up and as an audiophiles person i knew what this would sound like.......75 watts maybe per channel @8 ohms and i have it driving 2 rtr eviction series 15 inch woof 5 inch mids and high velocity horns rated at 225 watts rms and peak 430. pure mud!!!!!! lolol.so here is the catch it has pre outs rcas on back it is turned off until i get rpa 14 rockwell amp 700 watts rms. to over power speakers because now they are being under driven a VERY BIG NO NO.this reciever has standalone pre amp so when external amp is added internal amp on reciever does not have much work anymore making this a great setup......in theory.i will return with full and detailed info after i complete my cheap garage audio project and will detail everything to help who i can.......till next time. P S my 20 yr old sa GX 550 technics reciever rocks these rts speakers with only 330 true rms watts thats 165 watts per speaker. oh wel back to make a dime store stereo eventually blow out my nieborhood..if all goes right. ill be back good luck all. well i lost my left channel today then it came back but now very quiet and overall sound is degrading sorry this unit was cooked the day it was made very scary could have fried 800.00 speakers pure junk. also company has become MIA

Very nice amp. Sounds great seemed very powerful. Very happy with this purchase. Bluetooth worked great for me. I love the front display it is very nice. Might get another one.

Sounds good overall but has random static and a beep beep at low levels you can hear through the speakers.

First what I did not like. The hum. When music is not playing or paused the amplifier has an audible hum or buzz. Not unbearable but noticeable. However when the music is played the hum is gone. Now for what I do like. I am powering 16 speakers totaling 5,000 watts and this thing exercises them up to about 90% of it's maximum volume, and then the protec feature saves the amp. We are talking big boys, 18's, dual 15's and 12's... with huge box horns. You will feel it in your chest! By the way, the sound quality is so good that you do not need an eq.... The preamp knob is cleaning up the signal for you. Overall rating? Get one!

Great amplifier with a lot of power and easy to use. I bought this to power multiple speakers around my house. I will say it is very sensitive with protect mode, if any wires aren’t tightened or secured the amp will not work.

There is a terrible noise coming from the speakers when music is not playing. Wattage overrated. Knobs falling off, cheap quality. I think I will return.

Do not buy this Amplifier, I used it twice with good sound quality, after the second usage the sound quality is very poor. When I sent the seller a message I received no response. I would not trust anything they sell at this point. I purchased another amplifier locally and it is working perfectly!
