PocketWizard PowerMC2 Quick Manual - Using An Ac3 Zonecontroller
Using an AC3 ZoneController
An AC3 ZoneController on your transmitting ControlTL radio allows you to adjust the remote flash output power for up
to 3 zones independently, in either Manual or Automatic modes.
Set the Zone on your PowerMC2-equipped Einstein
™
E640 Flash to Zone A, B, or C as desired.
Manual Mode:
With an AC3 Zone Switch set to M (Manual), the AC3 Power Dial for that zone sets the absolute flash power output as
shown in the table for Basic Power Control. Your camera’s FEC/EC, ISO, and aperture controls will not affect the flash
output power levels for AC3 zones set to M.
Automatic Mode:
With an AC3 Zone Switch set to A (Automatic), Automatic PowerTracking using Center on ISO & Aperture with First Shot
is engaged. See the Automatic PowerTracking section for more information. The AC3 Power Dial for a zone sets the
flash power output level for that zone relative to the ControlTL center point. Your camera’s FEC control can be used to
adjust flash output power level for all zones set to A (Auto).
Off:
With an AC3 Zone Switch set to Ø (Off), flashes in that zone will not trigger.
