Using the MixPre-3 with a Camera and/or Tripod
The MixPre-3 has ¼-inch, 20-threaded screw mounting options on the top and bottom panels,
so it may be mounted to gear in a variety of ways. For instance, when mounting between a
tripod and camera, attach it to the bottom of the camera first before screwing it into place
atop the tripod.
To attach the MixPre-3:
1. Remove the battery sled to gain access to the back panel.
2. Retrieve the anti-rotation pin and Allen wrench. Both are
magnetically held in place on the back panel.

3. (Optional) If your camera has a slot for the anti-rotation pin, screw the pin into place on top
of the MixPre-3, and then position the MixPre-3 against the bottom of the camera so that
the pin fits into the camera's slot.
The anti-rotation pin may also be screwed into a tripod and slotted into the

bottom of the MixPre-3.
4. From the MixPre-3's bottom panel, insert the Allen wrench into the
mounting screw hole and push up on the retractable screw. Rotate
to screw the MixPre-3 into place underneath camera.
5. Align the mounting screw hole on the bottom panel with the mount-
ing screw on the tripod, and screw into place.
