Thanks for the info.

I have had no problems with RFI, but we have no TV

broadcasting here (I use two 680-1k ohm resistors and

a 100MFD cap in my pad...).

It is surprisingly like "good manual control" in its effect.

With the non-existent "overhead" in digital, unless the

source sound levels are under control, I get better results

with the AGC, modifying the results as needed in post.

This sure beats trying to fix clipping. The headphone amp

is both noisy and HF-peaked, and it is not representative

of what is on the track of the VX2000. BTW, for manual

LC use with the MKE-300, I would remove the pad for best

S/N...

The input maximum on this camera is too low for

very high sound levels without a pad, and with

relatively high-output mics like the 300, the

AGC "crushes" the peaks rather noticeably - you

should find the dynamics better with this mic

when using a pad with the AGC... (BTW, I don't

have a mic that won't distort when next to the

big bells in Cornell's bell tower - but, then,

my ears are in full "AGC-limiting" there, too...;-)

I've pretty much decided to switch from wireless

to MiniDisk this year - wireless has had too

many problems with RFI here in the last couple

of years (EVERYONE walks around with a cel phone

stuck to their ear...! ;-).
