Inputs & Outputs 

attenuate (or invert) with the Channel A attenuator knob. For example, with nothing plugged into
Channel A and the Channel A knob fully clockwise, 5V is sent out channel A. If the Channel A
knob is fully counterclockwise and its polarity switch is set to UNI , then 0V is sent out Channel
A. if the Channel A knob is fully counterclockwise and its polarity switch is set to -/+ , then -5V is
sent out Channel A.
