These cables break out from the 25 and 37-pin connectors widely used by sound re-inforcement and broadcast facilities companies. They are completely compatible with similar connectors from other manufacturers. All three types use individually jacketed Canford cables - 25-pin use FSJ8, 37-pin use FSJ12. XLR connectors are Neutrik NC3FXX and NC3MXX.
Manufactured by Canford.
Other variations of connectors and lengths are available to special order.
