Tonstörungen bei Hi8

Sound when Hi8



Frage von soeren12:
November 2006

Hello,

I now finally have a DVD recorder, bought for my Hi8 video to copy and secure, as does my Hi8 camera finally broke ...!
There are very strong hum constantly on! If the tape a few times out-and-forth rewinds, the same band playing here without the sound. This condition is unfortunately not exist. In general, the sound will return after a few minutes. These disorders are not dropouts in the sound but very strong loud noise, depending on the Originaltonlautstärke increase. That means in quiet places are synonymous, the low hum and quieter. Can these instructions with perhaps someone identify where the fault may lie?
I use almost entirely Hi8 ME tapes position of Fuji. Synonymous but have recently SonyMP time a play. As is well known, there are difficulties if these two places combined band. Could my problems come from? I have been synonymous, but a cleaning tape and run with alcohol all the band parts thoroughly cleaned. Then it just seems to be better, after about half an hour, we are again with the disorder.

Who can help me? I'm grateful for any hint!

Greeting

Yes, thank you.

I have now once again run a tape over and Headphones still observed that: In times where the sound gets Straker, one hears just before and after the sound in MONO. He often goes into the stereo. This is again synonymous but in no case s.tape or s.der recording, because when you get to a time back to the tape rewinds back office the same place felherfrei can hear in STEREO!
Who can give me a little bit more about the recording in Hi8 explain? The head drum is yes 4 recording heads and a delete head. The question now is: Are the two sound and video for two heads? Or do all four heads everything. If two heads are specifically designed for the sound, what is it?

Thank you in advance.

Greeting

Video8 and Hi8 used as the default soundtrack analog FM sound - in line like "hi" called stereo VHS models. The FM sound is much better than the previous video systems Randspurton usual, but has two disadvantages:
1. High-frequency sounds crackle - and although because of the FM sound of two additional rotating heads is recorded. The alternate 50 times per second - the Umschaltpause can only be limited conceal. Moreover, synonymous nor in the system specified Breitbandkompander (if anyone still s.dbx, HiCom and Co. recalls ...) anger ( "noise pumping").
2. Benefits or tape heads, the first sound of the threat - then you are of the described effects on.

Then it is so that the camcorder might be very abgenudelt is. Or possibly because synonymous helps proper cleaning?

My Hi8 units produce more image defects such as drop-outs, if a cleaning is necessary.

If in any case the experimental value. But when it's really wear is clean nothing helps ...
