There are several significant differences between the spinets and the ConsoleOrgans to reduce the production costs. Many of these differences do affect the sound:
-* Spinets do not have HarmonicFoldback. This eliminated a lot of extra manual wiring and allowed for shortened [Busbars
]. Foldback gives the console organs a significantly richer and distinctive sound in the upper octaves.
+* Spinets do not have HarmonicFoldback. This eliminated a lot of extra manual wiring and allowed for shortened [Busbar
]s
. Foldback gives the console organs a significantly richer and distinctive sound in the upper octaves.
* Spinets do not have ManualTapering. This eliminated all of calibrated resistance wiring used in the console organs. Tapering is used in the console organs to help eliminate keyclick in a more efficient way. It ''pre-emphasizes'' the higher frequencies and the frequency response of the pre-amplifier ''rolls off'' the upper end to restore the proper tonal balance. In effect, this reduced the sound of the high frequency keyclick. The spinet organs use amplifiers and speakers set to roll-off steeply after about 6kHz to limit the keyclick sound.
* Bass pedals are extremely limited on the spinets. This eliminates the steep cost of the 25-key radial pedal board and the larger bench. The spinets have only a single octave of pedals and the bass tone generators are wired to play monophonically. Unlike the console organs, however, the M series has a bass sustain switch on the expression pedal.
