module a-183-1 is a simple passive dual attenuator. 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-183-1 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.
this module has a maximum current draw of 0ma. it requires 4 te/hp worth of space to fit in a eurorack frame.
