The base-function of the AV2 is a dual attenuverter. To the two attenuverters a mixer with an
attenuverter on the output and a comparator is connected.
The combination of simple functions makes this a very useful module to have in your toolbox.
The unit can be used as a utility module for control voltages or to run audio through. It is DC
coupled.
When something is connected to A or B that signal can be attenuated or inverted and attenuated
via the knob. In the middle position the output is zero. Max clockwise you get 1 times amplification
through the module and any signal passes through unaffected. Max counter clockwise the
amplification is -1 times. That is 180 degrees out of phase with the input.
The LEDs shows the output voltage. Green is positive and red is negative voltage.

SUM

SUM is the sum of A and B after their attenuverters.
The knob on SUM is an attenuverter as on A and B.
The LED shows the output voltage. Green is positive and red is negative voltage.

Attenuverter

Input A and B

When nothing is connected to A or B the input of the attenuverter is
normalled to +5V.
This gives the possibility to set the output from -5V to +5V DC out via the
knob.
