Organ Control Unit (OCU)
This Organ Control Unit (OCU) is an "all-in-one" unit that combines the functions of both the Console Control Unit and Pipe Control Unit for a small organ.
Console Control Unit (CCU)
The Console Control Unit (CCU) is contained in a metal box, which has a hinged "pin-board" front panel where most connections to console switches and stop magnets are made. Three versions are available - for three, four, or five-manual organs.
