Review on 🔊 ICQUANZX Mini Dual 12-Level Indicator VU Meter Stereo Amplifier Board | Adjustable Light-Speed Board Module with AGC Mode | Assembled by Lisa Ramirez

In this price range it's hard to find fault. The device works well, there are several modes with and without peak hold, a good bright display. I still haven't figured out what they mean by AGC; Having a counter with AGC (Automatic Gain Control) would be self-defeating. I've found that I need to add a potentiometer (volume control) to get it within a usable range - the native sensitivity is too high for both home use (-10dB) and professional (+4dB) without that the game will be reduced, but that rather than not having enough profit. The first one I got had issues, but of course Revain is great at replacing broken bits.
