Pliant Dual XLR to 3.5 mm Cable, 4 ft

The CAB-DUALXLR-3.5 splits a single 3.5 mm mini male connector out to two 3-pin XLRs, one female and one male, giving you a line-level send and return on one four-foot cable. Pliant makes it for MicroCom XR and for the PAC-MC4W-IO 4-Wire I/O interface and headset adapter, which is where the two directions matter.

That pairing is what lets a MicroCom XR system tie into gear it was not designed around: a 2-Wire to 4-Wire adapter, a mixer aux and return, a camera, a recorder. Anything with line-level in and out at the far end becomes reachable without building a custom loom for it.
