11 LushOne 301 – LushOne Inca
Signal processor demo
•
Set up as shown
•
If you have a volt meter you can connect
to the “DC Out” to see the actual voltage
–
If you don’t have a meter just use the LEDs
•
Turn the gain to “min” and then adjust the
offset
–
You should see the output vary from about
-5V to +5V
–
Note that the input has no effect if the
gain is at minimum (gain = 0)
•
Set the DC offset to the centre (0V)
–
Adjust the gain while moving the joystick
up and down to vary the input
–
Note that unity gain is approximately 1/3
rd
round the travel of the gain control
–
Maximum gain is about x 3
•
Observe how the offset and gain controls
can be used together to set the absolute
voltage and the range of adjustment of
the CV
–
For non-inverting inputs:
V
out
= (Gain x V
in)
+ Offset
–
For inverting inputs:
V
out
= - (Gain x V
in)
+ Offset
