Step 4: Mounting the Receiver Step 2: Setting Up the Transmitter
There are many ways you can 
mount your PowerSync Receiver to 
your ash unit. Attach an adhesive- 
backed accessory shoe to your 
ash and the shoe-to-1/4˝-20 
adapter to your Receiver. Or use the 
Receiver’s 1/4˝-20 female threads to 
mount the Receiver to a light stand 
or mounting arm. You can also 
thread a lanyard through the 
lanyard hole and hang the Receiver 
from a light stand, ash handle, or 
anywhere else convenient.
The PowerSync’s effective range depends on the orientation and position of the 
Transmitter and Receiver. Reception can be affected by large metal or concrete 
objects and by bodies of water. Moving one or both devices a few feet is often 
enough to solve a reception problem.
There are two methods to connect 
the Transmitter to your camera: 
Hot-shoe mount
One method is to afx the 
Transmitter to the hot shoe of your 
camera. Slide the Transmitter into 
the hot shoe. The test button should 
be at the back, the same side as the 
viewnder. Tighten the lock wheel.
Sync cable
The other method is to connect the 
supplied sub-mini (2.5mm) phone 
jack to the Transmitter, located on 
the side of the unit, then plug the 
other end of the cord into the PC 
connection on the camera.
If your camera doesn’t have a PC 
jack, Impact makes sync cables 
with other plug types and in a 
variety of lengths. See the 
Accessories pages toward the back 
of this manual or check out the 
selection on our website.

If mounting to a ash unit, 
it’s best to place the Receiver 
so its antenna clears the top of 
the ash and is in direct sight 
of the Transmitter.
