IMPEDANCE
AMOUNT
This Parameter allows you to adjust the output impedance of the Tone Wheel Organ Types.
WHAT IS “IMPEDANCE?”
Impedance here refers to the AC load on a tone-wheel generator. When a note is played, it is “loaded
down” by the circuits related to the contacts under the key being depressed. When more keys calling for
the same tone wheels are pressed and held, the tone-wheel is loaded down further, causing a slight
volume drop on those related notes. This characteristic can be highly variable from one vintage Hammond
Organ to another, and the effect can be different on different organs built during different time periods
and using components of slightly different values. These Parameter settings allow you to replicate the
idiosyncrasies of different instruments.
The data chart below shows the options you can select.
IMPEDANCE AMOUNT
Parameter Description
Off No change in volume when keys are depressed and held and other keys are depressed.
Half When keys are depressed and held and other notes are played, the volume of the notes
being held is reduced by a small amount.
Full When keys are depressed and held and other notes are played, the volume of the notes
being held is reduced by the full amount.
Turn the VALUE knob to make your selection.
NOTE: The Half setting is designed to replicate the performance of a vintage Hammond Organ such as
B-3, C-3, etc.
