AUDIO INNOVATE Mini InnoFader DJM Replacement Fader
The mini innoFADER DJM is specifically designed to work in legacy Pioneer DJM-300, DJM-500, and DJM-600 mixers. It uses essentially the same componentry as the Innofader Pro2 so it also has the same 0.1mm cut point accuracy and 1msec response time. And like the Innofader Pro2, you get 1024 point resolution on the output.
Just in case you want to use this performance part on other Pioneer DJM mixers, it can be made to work with 3 pin connectors found on most newer DJM mixers.
