tisino RCA to 1/4 Adapter, Gold Plated Pure Copper RCA Female to Quarter Inch Jack TS Mono Adapter Audio Connector - Multicolor 2 Pack

The RCA part works !!!! However, I did not realize that there are other standard sizes for the small end. Which means I cant fit the small connector into the purchased adaptor. My bad but how do I measure an input? is there no standard?

These did not work well at all - lots of feedback no matter what I tried. I bought some different connectors that work much better without feedback.
