The X2 Splitter Unit allows for two unique inputs. X2’s two inputs are completely independent, allowing you to split two different signals separately. Routing a device into one of the top input ports will split its signal into two identical signals from the respective outputs. For example, this can be particularly useful when routing a signal (Input A) to an effect as a sidechain input; Output A1 can be used to sidechain while Output A2 can still run through the main mix.
