Need a picture to be able to tell you. There should be 2 sets of gold circle connections. the ones closer to the middle are the ones you want, but PLEASE give us a photo to confirm.

See this tutorial. https://synthiam.com/Tutorials/UserTutorials/100/1

Which pads you use depend on whether you are going straight to a speaker (can only drive a pretty small one without distortion) or going to an amplifier (want to use the line level, not speaker outputs to prevent distortion).

I want to hook up a 3.5mm in so I can hook up my amplified speaker (beats)

I watched the video on how to do it. But like I said in my post. Where he attaches the wires look slightly different than my board. edit: From the looks of the tutorial you sent I think I found my answer. It appears the gold surround on my board is where I am looking to attach the wire.

Thank You for the tutorial link. It answered my question.

Glad my tutorial helped. This is a great mod that really makes a difference. Too bad there isn't a factory installed jack but I do understand there is only so much room and money.

I have another question regarding adding the 3.5mm jack.

my jack has 3 connections (left, Right, Common) The tutorial only shows a ground wire and one wire in the via.

Where does the ground wire go on the 3 prong jack? And how am I suppose to get left and right when there is only 1 wire? Do I need to jumper the prongs?

You want to attach one point to the left, and the other to ground. You should be able to disregard the right channel.
