NOTE: Compatible expression inputs must accept a voltage source as the controlling signal. The expression input should also allow for an expression pedal TRS plug with the following connections: Sleeve = Heel, Ring = Toe, Tip = Wiper. The expression voltage present on the Ring of the TRS plug sets the maximum range of the controlling signal; this Ring voltage must be between 2VDC and 9VDC.
