I just got in my new Cinetronic monitor rods Friday, for a shoot I'm heading out on tomorrow. First of all, I want to say that it is beautifully machined, rock solid, and once I swapped out the clamping bolts for Kipp handles, it's pretty much the perfect monitor rod setup for me.
However, when I installed it, I got some wicked low-frequency vibrations coming through my monitor. I've fought monitor rod vibrations before, and I checked all the usual places - the mounting of the yoke to the rods, the rods themselves, the clamps, and I eventually found the issue - the plastic sleeve on the PRO post that brings the lower section to 1.5". Chris from Cinetronic offered me a smaller post insert for the rods that would have allowed me to avoid that plastic sleeve, but I wanted the versatility of being able to move the rods up to the main post, should I ever want to.
I did find a solution, after a lot of trial-and-error troubleshooting. Basically, if I aligned the cut in the plastic sleeve to either side, the whole rod and clamp setup became a diving board. By aligning the cut in the sleeve towards the back, however, it became rock solid.
I've attached a (crappy iPhone) picture of how I aligned it to remove the vibration. (ignore the dust... man, the flash on the iPhone does terrible things)
Hopefully this saves somebody else the troubleshooting that I went through upon getting their rods. I'd love to hear if anyone else with a PRO and the Cinetronic monitor bracket had vibrations from the same issue too. Now that I've got it sorted out though, I couldn't be happier. Gotta love that pan inertia!
