Hi,

I have an EX1R and have been slowly testing it in the field. On events with loud music I have found the same problem that Jim had. I tried using both the built in mic as well as two shotguns. All I did to adjust the audio was to put the Audi-In setting on Manual and adjust the levels. That does not cut it on the EX1R. Others here on the Cow have suggested that I lower the Trim Level, which is what I'll try next. (Ext Mic Input, Manual Audio, and bring the trim down). I'm thinking of bringing it down to the -32 or so range and adjust from there. I'm also going to try switching the high/low setting on the AGC, but am hoping that the low is not too muffled. I'm not sure about the gain setting but I initially am planning on leaving it on '0' and taking it from there. This time I'm bringing an attenuator as well,
just in case all in camera methods are not providing suitable results.

Re: Mics: I made the mistake of using a Sennheiser ME-66 indoors with very amplified (LOUD) sound. Not a good combo. Then I used the mic from the old DSR cameras (300/500 series) and that wasn't really much better.

So I'm going to purchase the Sony recommended mic: the Sony ECM-673/9x Shotgun mic.
It's an Electret Condensor and has a Super cardiod pick up pattern, (just like the DSR mics).
AND am going to experiment with setting the levels as described above.

There has to be a workable combo of mic choice and audio settings. It's just a matter of finding it.
With the EX1R, I've been recording sets that are not critical to the edit, so if they don't come out well I
don't use them, (I use other cameras, that I'm used to, for the critical footage).

When I find the right combo, (that works for me), I'll report back.

Good luck.
