The PD-MP motor is designed to give users manual control of their lens functions with the use of an external controller. It is compatible with the Remote Air 4, Remote Live, Remote Air Pro 2 & 3, and Live Pro. If you want to use the PD-MP only as a wired control system, you can simply connect your motor to the Remote Live thumb controller. If you want to use it with a wireless control system, you simply tether it to a PD-RX receiver motor. The PD-MP can also be used to upgrade your single-channel PD Movie products into a 2 or 3 channel control system. Every single channel system comes included with a hard case that contains 3 PD-MP slots in case you want to upgrade to a 2 or 3 channel system. The PD-MP offers a max torque of 1.2Nm.
