This is not new information.  The labels were reversed on some 
of the early production DB37-EL-K3 (and DB15-EL-K3 cables for 
DigiKeyer) from the factory.   

For the DB37-EL-K3 cables the 3.5mm plug with the female 3.5mm 
connector connects the K3 LINE OUT jack.  The single 3.5mm 
plug connects to the LINE IN jack.  

For the DB15-EL-K3 cable (for DigiKeyer) the 3.5mm plug with 
TWO small coaxial cables connects to the LINE OUT jack and 
the 3.5mm plug with ONE coaxial cable connects to the LINE IN 
jack. 

The labeling error was corrected on all cables in inventory. 
All cables produced since approximately 1 June 2008 are correct 
as they come from the production facility. 

Wire color code is NOT constant - colors will vary depending on 
the brand of bulk cable used by the production facility.
