Audio Damage Dr. Device - Manual (Page 7)

Operation
Dr. Device can be used in a mono, stereo, or mono-to-stereo context. In a stereo context, no summing of the
input channels happens; each channel passes through separate filters and delays. Dr. Device is useful as
either an insert effect or a send/return effect.
Here is a screenshot of Dr. Device, followed by detailed descriptions of its controls.
