A trip to Sweetwater yields this page
http://www.sweetwater.com/sweetcare/art ... out-guide/ which seems to show the same pinout as the Teranex. But this is the AES cable, not analog. A close look at the Teranex manual --section 12 -- shows the same pinout for both AES and analog. So for analog connectivity to Teranex, we need to use a cable with the AES pinout. The manual needs a revision to make this clear.
My need is for TRS connectors on the other end, and so far I haven't found a cable that works.
EDIT: It looks like I need to give up on the TRS connectors, and go with the XLR.
But, It would be helpful if you could specify exact cables that will work, by brand and part number. I don't want to fry the box by getting the wrong thing.
