This is the help thread for the M/S matrix.  A few guys are building them so I wanted a place to store some of the help info and docs as they come in.

Hi,
I've just received this board. It is a really good quality pcb.
Are the diodes bridges needed only for mic application as protection?

What's the significance of the word "link" printed on the Relay 3 and Relay 6 footprints? (And on the XLR pads?) Anything I need to consider before soldering RL3 and RL6?
 
One more question:

I'm using this as the I/O for a stereo EQ. I would like the mid out/side out and mid in/side in to be unbalanced. Can I just ground the negative conductor, or is that going to cause problems with the THAT chips?

Or, should I remove the chips and inject the unbalanced signal at Pin 6 on the 1200 line receiver and take an unbalanced out from Pin 4 of the 1600 line driver?
 
I'm using this in Integrated mode. Do I need to populate U7 and U8 and the components associated with them?
