Hello everyone,

i have my first shooting with lex and was capturing sound also with a shotgun mic connected to my XH A1, i didn't have earphones to check the sound and when i came back, all the shoot was with a buzzing sound from LEX vibration...

ok, no problem, as this wasn't something important to have sound during the shoot, but how do i get rid of this buzz??

Thanks,

Tomas

As far as I know, there is no way to get rid of the buzz from the LEX. That would be so nice if it is! The only way is to push that red button to turn the vibration off. As far as ways to prevent the mic from capture the noise is another question.
 
then let us focus on the later part of charlie's statement. How do we get rid of the buzz being picked up by on board mic, or shotgun mic.

What i have noticed is at certain tilt angles, the sound comes and goes.
 
actually sound exists no matter what angle it is... static buzz... seems like i'm gonna have to think something, put mic on a separate stand or smth..
 
then we are not talking about the same buzz. Because one is a buzz, and the other is a loud vibration, not a humming buzz.

A. Sorry, there is no fix - the buzz is the price of great looking video.
B. Audio options are to use wireless mics or a boom mic carrying soundman.
 
THere are several audio tools on the market that will sample the offending frequencies and then subtract them from the final audio file output.

The better programs cost a bundle.

Obviously the best way to get rid of the noise is to not have any.

Make a blip or use a boom pole.
 
get the mic off camera. there are two ways an onboard mic picks up noise from your rig -- vibrations from camera internals or even gentle handling traveling through the casing hitting the mic, and the other is from proximity to noisy sources. the former can be helped greatly with a shock mount. the only way to cure the latter is get the mic as far away from the source of noise as possible. lose the adapter, or boom the mic (or use lavs as mentioned above).
 
i think that most people who shoot with these adapters are aware of this, i guess the question is more of the very loud vibrating noise ( FOR ME ) that happens when i dip the rig at certain angles. I believe it to be a vibration that, as you say, travels throug hthe camera and rattles the on board microphone. However although the sound is never used, it would be to not hear a loud vibrating irritating sound when you are screwing around not capturing anything serious.
 
And even with wireless sound there are too many factors that can screw your sound at sub $1000 level. I`ve found that non-diversity receivers tend to be interfered by Sony MDR headphones cable for example.
I haven`t been able to record any decent sound onto tape ever since I started using Letus. It is really bad when your setup is on tripod that sits on wooden floor as the resonance will be heard all over the room.
