Hi Grumpy. An exellent technical paper on this subject can be found on the RANE Pro Audio website at (http://www.rane.com/pdf/note110.pdf). It includes illustrations for 22 different output to input scenarios which you may run into. Note that the pin-outs for XLR connections in this paper are for the European standard, which most pro audio manufactures also use. You may want to check with Fostex to see which standard they use as Fostex's main focus is pro audio. Hope this helps.
