I got an opportunity to see this HDV cam today and held it in my hands. Feels really good shooting hand held.

I know the specs for the his consumer version say there is not auto-limiting on the audio but I read an revew of the camera where they said there is a "peak limiter" on the audio. Is this what is also on the VX2100?

The review said the "peak limiter" on the HDV camera cannot be turned off. I was wondering if this is the same situation as on the VX2100 and if so then is it possible to bypass the "peak limiter" if I use an XLR adapter?


Here is the text from the Video Maker review of the audio:

"Audio Tests
The HDR-FX1 records a clean audio signal. You'll need an XLR to 1/8-inch adapter to get your microphone into the camera, but the jack is there, as is a headphone jack, of course. A user can switch between Mic and Line levels, although the setting placement on the menu is inconvenient. Switching between the automatic gain control and manual is a snap and a single dial sets the gain for both channels in manual mode. A plastic cover snaps back into place to protect the dial from accidental brushes once you have everything set up. There is a simple 2-channel level meter on the LCD and in the viewfinder, but it is not labeled with dB units. Our audio tests with a couple of shotgun microphones proved that the camera records a strong signal. The camera also has a peak limiter that has a fast attack and a slower release, but it cannot (unfortunately) be disengaged. "

the fx recording 2 diferent modes of audio
mpag 1 compressed 16?48 when you in hd mode , something similar to minidisk recording with some loose of information -lets say theat bad for musik and thats bad at all
and full pcm 16/ 48 in dv mode exacly as dvx ,pd-150,170 an cimilar camcorders
i dont know any thing about signal to noice ratio, maybe its good maibe it lousy , i hope it beter then 170
they dont say where is the limmiter , probably on the digital side ( after analog to digital convertion)
if the limiter is high enout ( om dvx it starts at -6 dbfs and ends - 4.5 dbfs ) thats could be problem if you recording musick or any thing that the limmiter can harm , for voice recording it might be ok
if it sits on-2 like the pd-170 thats not aproblem at all
, the camera if i dont mistake has atenuators on alog stage t -12 db -hat you can decrise or increase the signal( dvx has it on mike input -50,-60 db)
yothe line level probably some sort of attinuation onto mike level and not proper line input
the line is level for that camera probably -10dbv signa
if you work with mike levels you probably would need to block the bias voltage that is soplid (3v) dfor powering ext electeret mikes

personaly only becouse that i woudnt tuch that shit and waight for the pro model
not that would help any one in hd mode -same shit with losy compresion
double system if you run high quaslity productio
lets hope it match the dvx sound at least in dv,dvcam mod
