Frage von Stefan Koschke:
Hello,
I hope someone can help with:
I have a few years ago times a DV Converter Canopus ADVC55 purchased, the
And Toneingang has SVideo and Firewire on the whole digitized. At that time
everything ran fine.
Now, I have assembled a new calculator and the ADVC again (after
Years) was put into operation.
If I (as then) is now the inputs s.einen digital satellite reception
contagious, I get the sound in the recording massive hum.
I thought only s.eine "ground loops" but it is already buzzing when only the
a sound medium-sized stylus RCA plug is inserted.
By the second it will be even louder.
It will change nothing then synonymous next, if the ground (shield) Contact
has.
Has anyone an idea how to cope is?
Turn the power Reseivers has nothing.
Ciao
Stefan

That can still be ground loops. The usual route is via the
Schuko plug from the PC and on the ground the satellite system.
On power up the receiver you probably do not need to try.
A Feinschluss in one of the power supply is of course synonymous
not entirely ruled out. In this case, turn the power times
the computer center and / or put him s.einen other circuit.
For cable reception would be a galvanically separated by sheath current filter
in line with the antenna switch and everything would be good. In the bowl
it's not because of the LNB supply (except for certain
"Einkabelsystemen" that a DC-eh separation need). There is good advice
expensive. Actually you have to ground the satellite system to change
(leave), that the potential difference to the protection of your soil
Sockets reduced.

first thanks for the quick reply!
True, the times of the PC, I have not yet rotated.
All (SAT and PC) plug s.der same outlet (distributor), a
other circuit had

maybe yes, the synonymous, therefore, that a 4-way LNB is installed, the
other satellite Reseiver can hang naturally s.anderen phases.
The bowl itself is not grounded mW, from the LNB to the dish, there are
no conductive connection (plastic housing).
Perhaps yet another "good idea"?

Are initially suspicious devices with protective contact plug. For receivers is
the less usual, but with computers and projectors, with the receiver
may be associated. The network phase and the rotation of the plug can

It would be the grounding of a possibly existing satellite distribution gone.

There are filters for separating synonymous dei outlet. However, the cost so

now I can not see, but I think a difference to
previously found to have:
The new flat screen TV has (if I remember correctly) a
Kaltgeräteanschlußleitung with Schuko, the old television before, where
this is still no hum problems, had a normal 2 pole
Male.
The Reseiver and DVD player are all standard 2 pole times.
I will ausstöpseln all times and then bit by bit, back into operation
take, perhaps because there is the culprit!
Let's see whether what is there!

Yes, good idea. However, it is synonymous holding devices at the other people
, which s.LNB connected.

I have luck, all 3 (only 3 attached) are my Reseiver
own! :-)))
