nsm Digital Thunder adding microphone adapter board

[digitalthunder]

I have just acquired an NSM Digital Thunder jukebox and I want to install a microphone adapter board in it to input another music source into it for background music,  I will input through the rca plugs on the board.  I can't figure out where this board plugs into the main board.  One video I saw said that it plugs into the ST11 on the main board.  That plug in is not big enough for the ribbon cable on the board.  It is a 12 pin plug and the only place I can see to plug in into is ST9. Is this the correct socket to plug this board into?

I can't help you but there is a previous thread here that may or may not be of help. Maybe you'd already searched the forum and found it?

OK, maybe I can help you a little bit! If you look here, there is an ESV.1 training manual and the diagram on the final page shows the mic adapter connected to ST9.

Norman, thank you. That is exactly what I needed. The manual I got with my box did not have those diagrams in it. I wanted to be sure before plugging in the board. It works great, I plugged in an Amazon Dot Alexa and know I can play Amazon music until a CD is called up, then it fades out the Dot and starts the CD. When called up CD's end it switches back to the Dot.

Thanks again
