Hi,

ah, thats a single core cable David & if you connect it that way you will get 
issues. Basically doing that either leaves one pin empty or you hot wire 
between the pins & thats always going to have issues. 

the DPA's have a micon-dot connector & that goes to one of their XLR adaptors. 
Re-wiring them for the sake of plugging into the R-44 isn't an option of 
course. I use them mostly with my own set up (SD 7 series etc), but it'd be 
handy to find someway to do this with a different adaptor or something for when 
students want to use them together.
