AV2

Attenuverter

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.

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.

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.
