bobby1023d10 years ago000Is this compatible with pioneer VSX2020k AVR.dbeauc196510 years ago • purchased this product+1+10purchased this product Helpful answerYes. It supports both RCA phono and optical inputs on an AVR. The optical input on the vsx2020k is limited to only the TV/DVR/VID channels though so if you would want optical connection you need to use one of them.Comment
