Combine MK171 to the MK140

I would like to take the output (speaker leads) from the MK171 voice changer and run it to the input (microphone in) of MK140 karaoke, do you see any issues or problems doing this?


YES I do!
A speakersignal is MUCH too strong to feed into a microphone input! Make an attenuator with some resistors of at least a factor 100.
