Audio cable for testing Extron amplifiers

I made this 3.5mm to Phoenix connector cable to test Extron amplifiers. We have a lot of installs with Extron amplifiers and sometimes we have to test the speakers that these amplifiers are connected to. So what I normally do is to connect my phone to the 3.5mm jack and connect the Phoenix connector end to the Extron amplifier. Sometimes I connect the 3.5mm of the cable to my Bluetooth dongle so I can walk around with my phone. This is a very useful cable to have, purely for testing purposes. make one now for your testing toolbox!
