Most airport shops (well, the good ones) will sell headset Y cables, and many now have headset-to-camcorder adapter cables already wired for this application. The last couple of times I did this, I used a headset Y cable to split off the feed, and a line-to-mic attenuating cable. It worked fine. A passive mixer will work as long as it similarly knocks line level down to mic level (actually the headset level is a bit higher, but it's in the same ballpark as line level, so the line-to-mic attenuator was all I needed). Bear in mind you'll get a very "dry" track with no ambient sound. Something many people do (but I haven't tried yet) is to put a small lavalier mic inside one earcup of the headset. That way you'll get the radio traffic, but also enough ambient audio filtering into the headset to make the video feel right. If your victim in this experiment uses an ANR headset, have him/her switch off the noise cancellation for the duration of the taping. Alternatively, if you have a spare headset, drop the lav in it and rubber-band the two earcups together, more or less tightly to exclude more or less ambience. Cheers, Adam Wilt Canopus Raptor or Pinacle Stud - Adam Wilt 110% backing that. Pinnacle is worthless. Especially with the stock down to and change (from a high in the + range) due to an underperforming quarter and the rash of investor lawsuits subsequently filed! :-) Oh, how the mighty are fallen...

If you *know* that the analog output from your DV device is properly calibrated, *and* that the proc amp is properly calibrated, *and* you know exactly what levels trigger the meter responses you saw, then you can trust it. But I never trust a bit of gear until I measure it on a calibrated 'scope, which I why I suggested pulling the proc ampo out of circuit, and tweaking the monitor to guarantee you'll see any changes occurring in the picture. Cheers, Adam Wilt DV capture question - Adam Wilt However according to DVCentral.org's site, "DV data, not video, is > transferred electronically via the firewire to the computer's hard disk. > This not a capture process. it's a file copy process.... > My question is: Am I doing this DV "capture" right? Yes, you're doing it right. Technically, it's not a capture but a file transfer; operationally, you're capturing the data from the tape to the disk, so don't worry about the technical nit-picking! Cheers, Adam Wilt GL1 short questions - Adam Wilt For a realistic assessment of the exposure of the image, is the viewfinder > reliable? More reliable than the flip-out screen, since the eyepiece restricts the angle at which you view the LCD therein. With careful note-taking and practice it's a pretty good indicator, but always use zebra to be on the safe side. > Secondly, I find my old reliable Radio Shack lavalier mikes cause peaking > and static-sounding interference with the GL1. Try adding a Beacktek or Studio1Productions passive mixer to cut down the level. You might also try a different mic.
