The EWI YS cables are built with a molded Balanced Mono 3.5mm Male TRS on one end and 2 parallel male XLR on the other. The parallel ends are wired in a balanced configuration with the 3.5mm plug so pin 1 (shield) of the MXLR is connected to shield of the 3.5mm plug, pin 2 (red) is connected to the tip, and pin 3 (white) is connected to the ring. This is a fairly rare configuration for most 3.5mm applications and will not work as a stereo breakout cable.
The cable is constructed using EWI TWS-2503 stock which is a 26ga. twisted pair, braided shield, zip-cord style cable, making for a very high quality interconnect cord for your set up. Available in 10' and 20' lengths.
