Review on 🎵 Moukey 220W Dual Channel Bluetooth 5.0 Power Home Audio Amplifier - Sound Audio Stereo Receiver System with USB, SD, AUX, MIC Input and Echo, Radio, LED - Ideal for Home Theater Speaker via RCA, Studio Use - MAMP1 by Jabari Campbell

No instructions included but sounds good. A suitable receiver as a replacement for my SONY receiver, which has been falling apart for a few years.

That's typical of several tech products I've seen made in China or Korea lately, by the way. There can be no question of instructions. Maybe tech-savvy teenagers and millennials will understand right away? I'm not very
