The Doepfer A-183-5 is a simple, 4HP passive quad attenuator.
In this context passive means that each unit is made of two sockets and a 50k linear potentiometer only. There are no active parts like amplifiers or buffers and no power supply is required.
This is how the A-183-5 works: At the output socket appears the attenuated input signal, i.e. zero level at the fully CCW position and max. level and the fully CW position.
Applications:
Adjustable level of CV or audio signals to control other modules that do not have attenuators available.
