Review on Bluetooth 5.0 Stereo Audio Amplifier Receiver - 4 Channel, 440W Peak Power Home Theater USB, π SD, FM - 2 Mic in Echo, RCA, LED - Speaker Selector for Studio, Home - MAMP5 by Marcos Fiallo
Fan defective
The Donner amplifier was defective by default. As soon as I started using it, there was a strange noise in the background. Confusing. It wasn't in the audio. It was the amp's fan going on and off. It was loud enough to be annoying, especially when it turned on and off on up and down ramps. It was almost comical because the harder the amp got - when the full score was playing - more amps burned - the louder the fan got. A fan tried to keep up with the music! Funny but annoying. Send back.
