Problem: noise inside headphones with agdvx100a

Hi there,

I am experiencing a problem that seems to be known in this forum, I did not find any solution so I tried to write a new topic about it:

I connected a pair of headphones (SONY MDR-V700, sound isolating and good quality) to my camera while using an external mic (AT897).
I hear an high noise in the headphones that is not in the tape. I tried to change them with a cheap computer plantronics one and noise is much lower (but still present). What is the reason?
Is there a way to overcome this? I find it annoying because I cannot pick subtle noises when recording, it is too high for me.
lowering mic levels does not change anything.

Some advice?

Thanks in advance,

Cristian

Cristian,
If you are referring to the "hiss" coming through the headphone jack, it's an unfortunate "feature" of the 100a.

When you turn down the audio level controls, doesn't the hiss get lower?

hi, thank you for your reply

by lowering the audio level the hiss do diminish, but also the sound I need to capture so it is more difficult for me to feel if the sound is taken correctly and if all those subtle sounds are picked up.

is there a way to lower it? Or , do different headphones can remove this problem?
I fear you are suggesting me to get used to it.... :(

There may be some headphones which can cancel that white noise out but I don't know of any.

I have 3 different pairs of headphones (2-Sonys and 1-Panasonic) and the white noise is audible in all three.

FYI, I also have a PD-150 and a JVC DV500... same noise in headphones and it does not record to tape on either camera.

Yeah -- Use the AUDIO MON/VAR controls to lower the headset amp volume. Don't mess with CH1 AUDIO CH2 buttons on the bottom of the camera to try to fix THIS problem. The problem resides in the headphone amp. This DOES NOT get transfered to the camera.

Ignore it the best you can... complain often.

Good luck,

I think this is the result of Panasonic trying to address some complaints about the original DVX. Some said the headphone output was too low. (I never experienced it as a problem - my headphones worked great with it.) So they cranked up the output on the 100A to compensate.

FWIW these are the headphones I use with my DVX that have always sounded great. They only cost $20. Maybe you want to try turning down the headphone gain and using them instead.

Ehi guys
I really appreciate your help. I will try to use the settings you suggested, then I would try those audiotechnica phones.

If everything will fail, I'll make it an habit and will send a zillion of complaints to Panasonic

Thank again for your help, I will post results later.

Actually the MD7506's are probably accentuating the problem!

On the original DVX100 there was much complaining about the headphone volume -- but I never experienced that with my 7506's. I think there's probably an impedance mismatch somewhere, and the 7506's seem to be appropriately matched to the camera, where other headphones weren't.

So on the 100A, they boosted the output on the headphone jack, and now a lot of people are complaining about hiss in the headphone jack. Probably a direct cause-and-effect situation. But the 7506's never had a problem before -- so now they're probably doubly sensitive to the output of the jack!

Next time I use a 100A I'll test it with my 7506's.

Barry -- You really know how to kill a guy! I've got three pairs of the 7506s here right now. I edit on them all the time and LOVE the sound. Best picture I've ever heard. Everyone should own a pair.

LOL

Thanks
