Douk Audio VU22 Dual Analog VU Meter Display DB Panel MIC+LINE Sound Level Meter (Black)

Warm Tips 1. Without power adapter, and VU22 needs to be powered by separate USB power supply, don't use the USB port of computers or share the power supply with audio source, otherwise common ground noise will be caused. 2. Stereo RCA and 3.5mm AUX input are in parallel, two inputs and outputs will work simultaneously, so please don't connect RCA and 3.5mm AUX input at the same time avoid mixing.
