These fanouts have an inline multipin connector at one end and a fanout at the other with WI3M male XLRs on input channels and WI3F female XLRs or 1/4" TRS connectors on return channels.
Black XLRs have large pre-stamped identifying numbers. Fanout lengths: 3 ft. for 9 through 28 lines; and 4-1/2 ft. for 32+ lines. NOTE: When specifying the length of your fanout, the length includes this fanout length. i.e. a 32 channel 10' fanout has 4.5' of fanout and 5.5' of cable and MASS connector. Snakeskin® is applied to the fanouts as a standard feature. For information regarding why MASS connectors are designated INPUT or OUTPUT, please refer to: FAQ - Wiring MASS Connectors.
