The key contacts are connected through resistance wires to the
manual terminal strips. The manual wiring chart,
Figure 1–8 ,
shows how the contacts of each key are connected to the proper
frequencies to supply the fundamental and harmonics of that
particular key. The blank spaces indicate that no key contact is
used, inas much as the higher harmonics of these keys are not
required. Since the percussion control circuit is keyed through the
6th harmonic busbar, the blank spaces in this row have contacts
connected to ground through resistance wires.
The busbars of each manual, each one carrying a certain
harmonic, are wired to the appropriate harmonic drawbars for that
manual through the “Drawbars” tab.
