The Attenuators consists of three "passive circuits", each made of a 50k linear potentiometer 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.
Attenuators reduce the gain or amplitude of any applied input signal, control or audio. Moving clockwise from zero gain to unity with input, these attenuators can be used for reducing the effect of a control upon a voltage controlled module, providing up to three variable outputs from a single source input or reducing the gain of an entire signal complex.
This module has a physical depth of only 1 inch.
Knobs are subject to market availability and will be in flux until I find a new knob supplier. I will try to update this photo as inventory shifts.
