You can use Passive Attenuator with all synthesizers and modular systems. When you are producing music and patching, a most needed and current utility is engaged. Since it is on passive mode, it does not need a power supply. It has 3,5mm jack input and output. It can be used for audio and control voltage (cv). pATT does not occupy a place in your box; and while patching, it provides you the opportunity to add and take out in any manner and number. The jack inputs and potentiometers used in production are approved by RoHS and they are high quality. A voltage loss is not possible since it is in passive mode; and the sound it makes is transparent.
