MUSYSIC 4000W Hybrid Power Amplifier/Pre-Amplifier/Receiver with Bluetooth, AM/FM Tuner, USB/SD Slot, MP3 Input, and iPod Compatibility - MU-H4000BT Review

When I first installed the amp it worked for a while then after two hours it started making a strange noise and the audio stopped. I was horrified because it sounded like it was about to explode.

Not as white noise free as some say, but great sound separation. I hear that every instrument in music has excelled. My old amp just wasn't loud enough. This one is perfect for my small basement. A great buy for the price.

Excellent amplifier with great power and easy to use. I bought it to power multiple speakers in my house. I will say that in protection mode it is very sensitive, if any wires are loose or loose, the amp will not work.

It's not easy to connect to Bluetooth devices, the technology is very similar to small Chinese amps but bigger and more reliable but the basic functionality and quality is the same as these little chinese amps for a price i would buy a used yamaha and the remote is so cheap i didnt even give it to my customer i still give it 4 stars because of the good sound quality you dont hear any white noise in the Sounded which is good and I'm comparing the price to the quality so it's 4 stars

I still leave 4 stars because of the good sound quality you don't hear any white noise in the sound That's good and I compare the price with the quality that's why there are 4 stars

After ten minutes of amplification at 5/8 volume the sound quality began to degrade and before I could reach the amp to turn it off it went into protect mode. Apparently the exits burned out. I'm an electronics engineer. I need to replace the output transistors or IC. and circuits damaged by overload. This.; Resistors, capacitors and preamp transistors, most likely damaged as well. At least the protection mode worked, otherwise it would have completely destroyed the included logic circuits of…
