The PowerMC2 Receiver enables remote power control of Paul C. Buff Einstein E640 flashes with a camera-mounted PocketWizard MiniTT1® Transmitter or FlexTT5® Transceiver designed for use with FCC frequencies (North America). . PocketWizard ControlTL® technology allows you to control the flash power level using the camera's Flash Exposure Control (FEC). The PowerTracking feature automatically adjusts flash power to maintain the photographer-established level and thus proper exposure when the aperture and/or ISO is changed.
Simply slide the PocketWizard AC3 ZoneController into the shoe of the camera-mounted MiniTT1 or FlexTT5 and PowerMC2 linked Einstein E640 flashes can be controlled in three zones: A, B, and C in 1/3-stop increments over a six-stop range. Touch screen power control is also available with the Sekonic L-478DR.
The PowerMC2 can also receive Standard PocketWizard signals from Plus® Series and MultiMAX® Series transmitters. Set for Channel 1 at the factory, the PowerMC2 can be easily set for any of the 20 ControlTL or 32 Standard Channels and Zones using the Einstein E640 color LCD control panel. The PowerMC2 draws its power directly from the Einstein E640 flash remote control socket; there's no need to install or replace batteries.
