The front panel
64 control knobs/potentiometers
Drehbank incorporates 64 control knobs/potentiometers that have a control
voltage range from 0..+5V. Internally the control voltage is translated into digitial
information. A full turning of the control knob has a range of 256 values from
0..to.255.That means that the variables have a range of 256 steps.
Note
There may be slight fluctuations in the potentiometer tolerance levels for
which we accept no liability.
The spacing between the potentiometers is rather small. We know. This is a
compromise owing to the exeptionally large number of control knobs. Would you
buy a unit that‘s 8 feet long?
☺
64 Labelling pads
These pads allow you to label each individual control knob for easy reference of
your setups.
Note
Only use light pencils when writing on the labelling pads, otherwise it
won‘t be possible to use the pads again and again.........
SWITCHES
On the left of the unit you`ll find 3 black switches with the following functions:
R E C A L L I N G T H E O R I G I N A L S E T T I N G S / R O M P R E S E T S
As you will see the Drehbank unit has no ON button/switch. To activate the ROM
presets you must press a switch at the same time as you plug the power In (see
the README.TXT file).
The indicator above the pressed switch will not light up, but instead the other two
indicators will flash.
E.g., when turning the unit on you press switch 1 (the top switch), to select ROM
preset 1. The L.E.D. above that switch will not light up, but the other 2 L.E.D.s will
light up. This inverted indication system also goes for the recalling of the other
presets.
This means that the Drehbank at that moment loads the ROM preset and will wait
until you release the switch.
After this the Drehbank returns to normal operation mode and switches to bank 1,
the L.E.D.s are now also in normal operation mode.
Now the Drehbank is ready to ROCK.
