Control expression and aux switch functions on the Eventide H9. A switch can also be connected via the input allowing you to choose between either the internal or external aux switch.

An LED indicates that the expression pedal is connected correctly. The SP-H9 is powered via the TRS cable. No battery or external power supply is required.

The Mission SP-H9 connects with a single TRS cable and has both an expression pedal control and an internal aux switch. An additional input allows an external TS momentary aux switch to be used in parallel with the internal switch if required.
