Here is the completed jackbox being installed. Jarrod
is soldering the wires on the junction board. The teleco cable can
be seen going up the wall and to the right where it will proceed to the punch
down block array. One cable carries the input stream for controlling
the jack toggles. The input stream comes from the MIDI system or the
roll player (Concertola), depending which system is in use. The other
cable is the output from the toggles and carries signals to the the stops, couplers, and swell shades.
The wind is supplied by 3 inch PVC pipe. The entire
organ is winded through PVC pipe that generally runs between floor joists
and then turns up or down to supply various parts. In this picture,
the pipe continues to the right to supply wind to the relay and coupler systems.
At the right of the jackbox is a small regulator for the jackbox..
Just below the regulator is the player sforzando switch which is enclosed.
This switch is programmable so that any resource may be included in
the sforzando function.
After this picture was taken, the area where Jarrod is standing became
the location for the swell engine for the Swell enclosure. A
system of cables and pulleys actuates the shutters, and the bulky (and noisy)
swell engine is in the uncrowded basement area below the Swell enclosure.
