Re: Monitoring audio in the DVX100P
The echo is normal on a 100A in 24P mode. There should be no echo in 60i, nor should there be an echo on a DVX100 (as opposed to the DVX100A).
As for the levels, you'll have to check the line/mic switch, the Mic Gain settings, and the audio level dials to make sure you're getting good strong levels.

Re: Monitoring audio in the DVX100P
That doesn't sound normal (pun intended) to me, although a lot depends on the equipment you're using, my experience is with good headphones (I'm using the Shure e4c in-ear), I get excellent reproduction, so that even when I see my levels are low, I hear a fairly accurate rendition of loudness, tone, etc. When the actor hits higher levels (emphasis, scream, etc.) and I see the levels in the high red, it sounds louder, relatively, as one would expect. In other words what I see on levels jibes with what I hear in the monitors.
Similarly, when I play back on my studio monitors, I pretty much hear what I heard in my e4c. The only thing I hear more of in the e4c is a slight hissing which must be due to the in-ear design (and IS slightly annoying)--none of that ever makes it onto my tracks in either the DV playback or the files when uploaded via Final Cut Pro.
Equipment:
AT-897 (used w/phantom power, but tested--with same results, using AA battery)
Shure e4c in-ear monitors
Straight into DVX100A via 50' XLR
M-Audio BX-8 studio monitors

Re: Monitoring audio in the DVX100P
hey, its good to read this!
am having this very problem (echo on the headphone, very low audio on the tapes) have been researching the net now and found some few postings of people with the same problem, but no solution anywhere. (one person said she had posted a thread about this on dvxuser, but i cannot find it)
the echo on the headphone got better after using a bullet proof headphone and turning the volume way down. but afterwards i discovered that the sound recorded to the tape is poor and very low. e.g. on a tv i have to put the sound volume all the way up to hear anithing at all and the sound track in post looks simply ridiculous.
any ideas? is this something for repair and service?

Re: Monitoring audio in the DVX100P
It's my understanding that the echo is normal for 24p shooting. I think it's because you are looking at 24 frames per second but the audio (and the video, for that matter) is still being recorded at 30 fps.
In order for you to see the video and hear the audio in sync, they had to diddle with the monitoring output of the camera. So it echoes.
But it won't be echoing when you export it to your editor.
I could be completely wrong about the explanation, but not the "normalness" of it.

Re: Monitoring audio in the DVX100P
Yea, I always get the echo in 24p. I'm fine as long as I don't leave my cans on when I'm talking to somebody.

Re: Monitoring audio in the DVX100P
24P will echo in the headphones. Do not turn down the potentiometers on the camera to get rid of the echo! You want to make sure you're recording strong volume to the tracks. On the 100A you can lower the headphone volume if you want, without changing what gets recorded on the camera.

Re: Monitoring audio in the DVX100P
yep, sure, the echo seems unavoidable, thats clear now.
and of course one can only turn down the headphone volume, not the level control knobs.
but still the camera records very very low audio with the level controls on mid to high. ???any good ideas on that?

Re: Monitoring audio in the DVX100P
What do your levels read while you're shooting? I think I read somewhere on this site that 2 reds on the LED is good for peaks.

Re: Monitoring audio in the DVX100P
The camera can record just as loud as you want it to... depends on what your level meters are reading out.

Re: Monitoring audio in the DVX100P
okay, have been testing the audio once more:
1. speaking directly mouth to mic into a akgc1000 with normal voice, level knobs to the middle position: 3-4 slashes visible on the camera monitor levelmeter
2. speaking with a strong loud voice, level knobs all the way to the top i get -12 to -10 db (about one slash into the red)
i guess this is NOT normal, is it? so after all i guess the camera needs a doctor.... :-(

Re: Monitoring audio in the DVX100P
Try changing the mic sensitivity in the menu, I'll bet that fixes it. Change from -50 to -60, or from -60 to -50, and try again.

Re: Monitoring audio in the DVX100P
To all of you wondering about the echo, I believe that the echo isnt happening in the headphones. What it sounds like to me is that the audio coming through the headphones is slightly delayed, and mix that with whatever ambient noise you hear (the actual sound that bleeds through) it seems like there's an echo. Test it by tapping the front of a boom mic while in 24P mode and you'll see what I'm talking about. From what I was told, in order to better sync up the audio to the video in 24P mode, the audio is delayed slightly to compensate for the pulldown, which would explain the echo.

Re: Monitoring audio in the DVX100P
Yeah I have, I hear it at mic level as well as line level. I'm almost positive that the echo is caused by ambient audio mixing with audio you hear in the headphones. Sometimes I will push my headphones onto my head to further isoloate the ambient noise and the echo goes away.
