The Standard Electrical Dictionary

1. Organ, Electric

   An organ in which the air blast is admitted or excluded from the different pipes by electric mechanism. The outlines of the system are a series of contacts worked by the keys and stops, which cause, when operated by the organist, a current to pass through electro-magnets, opening the valves of the different pipes. Thus the manual may be at any distance from the organ, and a number of organs may be worked upon the same manual. As many as five in a single cathedral are thus connected to a manual in the chancel.
