DESCRIPTION
Another addition to our ADDAC300’s Expressive Controls series
This module converts the incoming light hitting an external light sensor
into 2 Bipolar CV Streams:
Output: More light > Higher CV output
Inverted Output: More light > Lower CV output
The external sensor is enclosed in a jack socket in order to be used
with any standard jack cable and be able to place it in any place
outside the eurorack frame.
There are several controls to adjust the CV Output’s signals:
Sensitivity:
Adjusts the Light Sensor sensitivity to Light
The Higher the sensitivity the better it responds to low light situations
Response:
3 fixed settings (medium/fast/slow) to set the slew applied to the raw
signal coming from the sensor.
Gain:
Sets the gain for both outputs
Offset:
Adjusts the Offset for the main Output.
Inverted Offset:
Adjusts the Offset for the Inverted Output.
Specs:
4hp
±50mA
4.5cm deep
