SkeletonDAC Question

post #1 of 3
Thread Starter 

I'm rather new to the whole DIY scene, and as such, I'm making the cheap/easy SkeletonDAC from Beezar my first project. 

 

http://beezar.com/catalog/product_info.php?cPath=41&products_id=138

 

The kit that I'll be using does not come with a headphone jack component/socket, and the only ones that I can find are either 5-pin or 3-pin, while the completed DAC in the photo ( http://beezar.com/catalog/popup_image.php?pID=138&image=5 ) has 4 leads connecting to the jack. 

Can somebody explain to me why there are 4 leads instead of the three that I'm used to (Ground, left, right) and what pieces I should buy to be able to complete this DAC? I own a multi-temp soldering iron and most of the other equipment that I'd need to complete this.

I double up on the ground connections, especially since there are two positions in the PCB.  A bad ground connection on the analog input or output can cause a multitude of problems.  (Cobaltmute, the DAC's designer - agrees in principle with this, too - and supplied the two ground connections on the PCB.)
 

IOW, those are two ground wires run in parallel connected to the same pin on the jack.  The jack is 3-pin.

I was expecting something like this, especially given the coloring of the cables. Thanks so much for the info! I'll be ordering my kit soon.
