The shockmount was attached to my diy microphone stand which is pretty stable. The microphone point around 45 degree downward which is the best configuration I have known of.

I think the original "007 wind-screen" might have been misunderstood. The guy didn't use a foam inside the windscreen. The silk was supposed to take care of of everything.

The original Sennheiser "zeppelin" also used silk on the inside, behind the plastic mesh. But it was rather heavy. By being the "007's" silk farther from the mic (diameter was around 8" wide), the slowed wind affected the MKH416 very little. And by being made of balsa wood it was very light.

The silk shouldn't flap or mode, but being too tight isn't too good either.

Though the main thing is that the silk be "sound transparent". You should try the type you are using by talking to the mic through it and without it, to see what changes. And you should blow through the silk to see how much the silk stops.

Hi Carlos,

Thanks for clarification.

I will try to remove the foam which is very easy.;-)

Be careful with that. Doesn't the 5000 have some sort of attenuator?

A mic pot should be around the middle as a routine. If levels are higher or lower you should use some help, from an attenuator cable or a preamp.

With digital audio, sometimes higher levels can be worst sounding that low levels increased during post.

Hi Carlos,

Thanks for the advice.

One cameraman Case told me to buy AT8202 Attenuators several days ago. I was just thinking to save some money and omit that one if I can. Now I think that I have to get one.

Hi Carlos,

May I ask if a cheaper second hand low end multi channel simple mixer will help the situation? i.e. this one Click here

TIA

I made a test video to compare the performance of silk windscreen against no windscreen, foam, foam with silk windscreen combination using a desk fan.

The test configuration is still the same as listed in my previous post.

The video file is around 60mb encoded with wmv format.
