The AC 31 from Neumann is a cable for connecting the Neumann Miniature Clip Mic (MCM) system to bodypack transmitters with a 3.5 mm (0.13 in.) jack connector. With 5.9 feet in length (1.8 meters), this cable is Kevlar-reinforced for maximum strength and high flexibility. Additionally, the KC 1 cable bridge can be used to secure the connection between the cable and the gooseneck. This is included with the gooseneck but can also be purchased separately.
