Controls
1. Channel A attenuator
Sets the amount of attenuation for the IN A input. The behaviour of the knob depends on
the position of the polarity switch [2]. The attenuation amount is linear.
2. Channel A polarity switch
This is a 3-position switch that sets the polarity of the of the OUT A signal:
With the switch in the right position the channel functions as a standard attenuator.
OUT A outputs the unmodified signal from IN A when the attenuator knob is fully
clockwise and no signal (0 V) when the knob is fully counterclockwise.
With the switch in the left position the channel functions as an inverting attenuator.
OUT A outputs the inverse of the signal at IN A when the knob is fully clockwise and no
signal when it is fully counterclockwise. For example, if the input is 5 V the output will be
-5 V with the knob fully clockwise.
With the switch in the middle position the channel acts a bipolar attenuverter. The output
is the unmodified input with the knob fully clockwise, the inverse of the input with the
knob fully counterclockwise, and 0 V when the knob is at the 12 o’clock position.
3. Channel B attenuator
Behaves the same as the Channel A attenuator but for channel B.
4. Channel B polarity switch
Behaves the same as the Channel A polarity switch but for channel B.
5. Channel C attenuator
Behaves the same as the Channel A attenuator but for channel C.
6. Channel C polarity switch
Behaves the same as the Channel A polarity switch but for channel C.
