VOLUME Knob
This knob performs different function depending upon the unit’s mode of operation. In normal
mode it works as volume control knob.
It is also used as a data input device in various Function modes to program the unit. For example,
it is used to set the BALANCE adjustment when the VK-31 is switched into its Balance mode.
More on that in the corresponding sections of this manual.
The volume control knob on the VK-31 is linked to a digital encoder and is of a continuously
rotating type (there are no stops).
