Review: Excelente - Good
Review: I love that they came with two kinds of screws - They came with both wood screws and machine screw + nuts. I used the machine screw nut combo to put 8 inputs on a 1u rack plate. There is no marking about ground vs signal. The bottom terminal is ground. If you’re using TS cables you can solder signal to either left or right prong. I soldered to the left. (I’m not sure about TRS/balanced/stereo because I’m not doing that in my situation and I didn’t test it. Sorry!)

## Questions & Answers

**Q: What wire should i use to solder this ?**
A: I had up to 16 gauge on mine.

**Q: How can it be both mono and stereo? And if so, what 2 pins are used for mono?**
A: "Mono" and "stereo" terms are misleading here. The correct label would be "balanced" and "unbalanced". A "balanced" connection would use all 3 pins, #1 being Ground, #2 being the Hot or positive signal and pin #3 being the Cold or negative signal. An "unbalanced" connection would use only pins #1 and #2, ignoring #3. 
You could create an "unbalanced" "stereo" connection where pin #1 is ground and common to both "sides", and pin #2 would be "left" and pin #3 would be "right". This would be a typical headphone jack. 
If you are using this for an instrument cable connection, such as a guitar, use pin #1 as ground and pin #2 as Hot or signal. You would not use pin #3.

**Q: Which post is for Tip, Ring, and Sleeve?**
A: I dont remember off the top of my head, but if you have a TRS cable or TS cable, you can plug it in and do a continuity test to find out which is which

### ⭐⭐⭐⭐ Mixer rack inputs
*by T***X on August 3, 2019*

They're good plugs. Wish they where labeled on the back which is Tip, Ring and Sleve. Ohmed things out and made stereo inputs for my mixer rack. Workes fine for me. More for inputs than outputs.
