I had some fun with the first one and thought the ability to A-B between two different settings would be cool so John stepped it up a notch.
It is a stereo unit with only 2 RCA Jacks.
This is just another prototype and for those of you who haven't figured it out, it is a remote controlled load resistor. My initial use for it was to adjust the load a MC cartridge sees and it is a great educational tool!
Stay tuned.... we hope to have a finished unit and John will have boards available for OEM's to add this functionality to their devices.
