Amplificateur audio stéréo Bluetooth 5.0 100W 2 canaux avec récepteur BT - PrimeCables®

2/5

This "Made in China" amp has no branding; that should be a warning to you. I hooked this amp up to my new oscilloscope and ran some frequency response tests with a signal generator. The amp is awful. The high-frequency supersonic class-D pulsing leaks out. It clips at moderate volumes. (The power supply is only 24V at 4.5A, which can't possibly produce the rated 2x100W of the specifications.) The amp has a huge phase shift at low frequencies. At high frequencies, there is aliasing and waveform distortion at some frequencies and the frequency response has a huge rise up above 20KHz. (Lucky we have no dogs in the house.) If you only listen to low-quality MP3s or heavy metal music then maybe you won't notice how bad this unit is. At least the Bluetooth works.
