Luxman RC-401 Infrared Remote Control Command Splitter & RC-403 Repeater, includes cable labeled 'use for connection between Luxman RC-401/RC-403 and Luxman R-406/LX-104'. I don't have the items these plug into so they are all untested and offered 'as-is'. The Command Repeater requires 4 'AA' batteries (not included), the battery terminals appear to be very clean and the unit includes the battery cover. Thanks for looking!
