Best Meter Power Supply

Retro Dual Analog VU Meter RGB Sound Level Indicator DB Panel Display

This is not a speaker, not tubed power amplifiers, no Bluetooth, not rechargeable.
It is a voice-activated VU level meter that oscillates to ambient sounds and follows the beat when there is music. There is a row of RGB lights in the middle grille that can adjust the mode and colour themselves..
Newly designed VU level meter with gold plated circuit board and backlit VU meter head. The microphone uses the same silicon microphone used on mobile phones and is extremely sensitive..
The whole unit measures 160mm x 44mm x 54mm, the power connector is Type-C, the supply voltage is 5V and the connector is located on the back for easy cable routing..
Accessories include a 1m Type-C power cable and 5V power adapter. The product is handmade and has been assembled..
