LM-3S Output Voltages
« on: March 29, 2021, 08:47:09 PM »
So what is the voltage output from each of the output wires (output #1/white, output #2/yellow, output #3/green, output#4/violet, output #5/green, output #6/violet) and the two brown speaker wires as depicted in the wiring diagram shown on the bottom of page two of Ring's LM-3S Installation Instructions?

https://www.ringengineering.com/RailPro/Documents/LM-3Instructions.pdf

I've got an idea of what they are but I can't seem to find the values (as designed by Ring) delineated anywhere. You know the old saying, "inquiring minds want to know!"

Covered way back here: https://rpug.pdc.ca/index.php/topic,189.0.html. The output voltage is about half a volt lower than track (ie, input) voltage.

Speakers I have no idea what they are fed with.

Thanks Tim!
Sorry for having posted a repeated topic.  :-[
I performed various searches using different words/wording each time and never came across that thread. Perhaps because of its age/date it was a couple pages back in the search results and I never paged back that far.

No apology needed! No worries!

Yep, no apologies needed.

That topic was for the LM-2S but the output voltage didn't change from the LM-2S to LM-3S.

Handy hint: if your searching for something using two words that you want to appear next to each other, eg output voltage put them in a pair of quotes vis "output voltage".  This reduced the search results to 17 from 52.
