Audio Analyzer - Analog Discovery

Audio Analyzer - Analog Discovery Introduction

I have been using this Analog Discovery to run tests on amplifiers and receivers that I have been repairing. The Audio Analyzer Suite (https://www.youtube.com/watch?v=4d3hc-9zBaI&t=1063s) is a free software available for the Analog Discovery II that has several built-in tests to run and also works as a Spectrum Analyzer or Oscilloscope. I have attached a few of the automated tests from one of the amplifiers I have tested. It is configured so the amplifier or DUT is connected to the Banana Jacks on the front, there is a switch to route the amp signal either to the speaker connections on the back or to the Analog Discovery II with the 2 x 100w 8ohm resistors being used as a Dummy load. The switch in the center was originally in use to make the 2 center outputs the same but I found I wasn't using that feature - the 2 additional BNC connectors on each side are for connecting to a scope/meter for other testing. I am selling because I have 2 Analog Discovery's and have set up the other one for the same purpose. I would be willing to modify or customize it if needed - let me know if you have any questions. Thanks for looking :)
