Attenuators
The Attenuators panel consists of three passive circuits, each made of a 25k potentiometer (think of it as a variable resistor) between input and output. The signal input to the top attenuator is chained to the bottom two in series. Introduction of a phone plug into middle or bottom input breaks the normalling system: 1 to 1-2-3, 1-2 to 2-3, 1-2-3 to 1-2-3. this means that the module can also be used as an unbuffered distributor.
