Operation
Faders
Since there are only 4 physical faders, only 4 faders can be
manipulated and shown at any time. The use of all 8 faders is
accomplished through “bank switching”. The faders are arranged
in two groups of 4 faders. The Inc/Dec button selects the bank to
make active. When the unit is first powered on, Bank 1 (faders 1-
4) is active. When the INC button is pressed, Bank 2 (faders 5-8)
is active. Bank 1 can be selected by pressing the DEC button.
The FaderMaster 4/100 internally keeps track of all 8 faders. For
example, if the INC button is pressed, the FaderMaster 4/100 will
remember the settings of Faders 1-4. Pressing the DEC button will
restore the faders to their original positions.
Additionally, if the computer made updates to the fader position,
those positions would be remember even if they were part of a
bank that was not currently selected.
This also holds true for the LEDs above the faders. The
FaderMaster 4/100 will remember the settings of the LEDs when
the banks are changed.
