Friendly Tips:
1. No power adapter The VU22 requires a separate USB power source. Do not use the USB port on your computer or share power with your audio source. Otherwise, it will generate common ground noise.
2. Stereo RCA input and 3.5mm AUX input are connected in parallel and both input input and output work simultaneously. Therefore, please do not connect RCA input and 3.5mm AUX input at the same time to avoid line mixing.
