Sound Break Out

The bottom of my EZb V4 looks different slightly from the video I watched here for adding a 3.5mm jack. The ground hole is the same but there is only one hole with the gold colored surround in the area where I would think the power wire goes but Just want to make sure because it is slightly different from the video. Is this the spot where I would solder too?

I just got my V4 in January 2016.

Thanks for the help

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?

#8  

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

#9  

So Left channel to Via and the ground to the common/shield tab correct?

yeah - if you get ground from the battery or before the EZ-B, will reduce any noise.

#11  

What do you mean? (I am not experienced with electronics) Are you saying not to use the ground port on the v4 like in the tutorial?

#12  

I used the EZB ground connection and wired the single audio channel output to both L & R connections.

#13  

Did you just a jumper to connect the L & R connections on the jack?

yeah the L and R of your audio connector can be connected together.

When i mentioned where to connect the GND - that can be the "black" or "gnd" at the battery, or the power pin of the EZ-B.

GND is also called "Common". This is because all devices can have different Positive Voltage, but they all must share a common ground. For example, in your house, ever breaker/fuse for every plugin is different - but the ground is the same. It's a common ground because everything needs that common ground. The earth is pretty much the biggest common ground you can find :D

Thank you for the help! This is all new to me and I don't want to screw up my EZ-B. Appreciate you explaining it in a simple manner.
