Quality of EX1' mic-preamp?

I wouldn't even call it "foam." It's more brittle than the cover on the shotgun that came with the PD-170. Yes I need to get a proper cover for it. I wish I could try before I buy. Rycote is trustworthy/expensive and has many choices from short hair on camera to windjammers, etc..

The Windpac-L from DPA is probably the most effective device for stopping wind. It's way too big for use with a camera mounted mic and is expensive. It does however give almost no HF attentuation. The design would seem to provide the protection in much the same way as a popper stopper on a studio mic.
If you've got the budget probably worth a look at as DPA is not a company that comes to mind with field audio.

I noticed the excessive wind noise with an Audio Technica shotgun mic with the standard foam microphone sheath. The low-cut switch was on. I've used the microphone outdoors with my Sony Z1U, and I never had this sort of trouble. Hmmmm. I have AGC off and the wind cut parameter off. In fact, I've had quite a bit of adjustment needed since switching from a Z1U/FX1 pair to this EX1. In the past, I just plugged in mics and adjusted the external gain knows. The EX1 seems to require some futzing.

Too many issues for me to consider at this time. Let's see what NAB brings and if Panasonic is ready to introduce something that will compete with the EX-1.

I had similar issues initiall with the VX2000. I think we were hoping that microphones will work the same way when stuck on the EX1. With the default input trim settings, the microphone signal level is too low, forcing us to crank up the input gain with the external knob.

So Craig, it seems the recipe I have given earlier in this thread is working:

Nevertheless, I don't like the fact that to be protected from _potential_ overloading, one needs to set the trim level really low; already with -38dB, the waveform display I'm getting after importing to Vegas is almost flat...

Luckily enough, the overall sound quality of the EX1 is sufficient to be able to effectively turn the sound level up in post, without introducing too much noise.
