The signal routing of Insert-Send/Return or Stereo-L/R into a single jack connector is cost-effective, space-saving and, therefore, often used. The "Fairline" Y-adapter cables create transitions to the respective individual connectors for such cases. The connectors have been designed for Cordial by REAN which combine injection molding with metal coating and can be opened and repaired if necessary. In addition the the cable is split by a Y-splitter developed by REAN for Cordial.
