Frage von Räuber:
Moin, question s.The Micro-specialists. My FX 1000 has only the handle as micro input. Will soon need a 10m distance, as is the normal cable I suppose very prone to damage. Now have an adapter with Conrad seen XLR - jack. Does it make sense to have the appropriate adapter between the Micro and camcorder a 10m-connect XLR cables, ie the positive properties are preserved?
Thanks and greetings, Stefan
Antwort von srone:
if you use this adapter or not does not matter, symmetrical signal transmission takes place only if both participants microphone and microphone input are constructed symmetrically, otherwise very susceptible to failure unbalanced transmission.

Moin, I have a similar cable of Thomann
(http://www.thomann.de/de/cae_20035_kamerakabel.htm?sid=ca406494f91bc3d068e396eb5bc8e5db) and can only speak good of them. I used it, inter alia, for a video interview and was synonymous with this cable wonderful sound!
And if you to use the XLR adapter cable, you will remain synonymous, the positive qualities of a XLR cable!

And if you to use the XLR adapter cable, you will remain synonymous, the positive qualities of a XLR cable! What are the positive characteristics of a XLR cable do you think, this applies to balanced signal transmission characteristics which held that same positive only if both the sender when the recipient is synonymous symmetrically, what the microphone input of an fx-definitely not 1000 (!) is, and Thus, the whole transfer system is entirely unbalanced with all its disadvantages.
synonymous, see here:
Antwort von Räuber:
Hello SRON, had feared that the quality is not better to respect well, but then just the normal cable and synonymous interference and eliminate them, if necessary.
THANK YOU!

Antwort von srone:
the basic quality is not bad but synonymous with unsymmetrical transmission (under ideal conditions, ie without external disturbances of). symmetrical only significantly troublefree, outside under what conditions is not to assess a significant advantage.

Antwort von mov:
The crucial part of Balanced transmission, usually the receiver is either a transformer or an OP AMP, which compares the two signals with each other and only the differences in outputs, perturbations beidne wires are then erased. The signal itself need not be symmetrical, with only two wires to the source take place, as interference still be included s.beiden veins, and can thus be removed from the receiver.
In this case, it is the other way, the source is symmetrical, but the builtin can not do anything. Therefore, using XLR cables that nothing, except that it is more stable than a consumer mini-jack cable.
If the microphone has an XLR output, then it is definitely useful.
Betting On Set Of The fact that in Friedrichshafen has such a cable marked perturbations of the fluorescent lamp decoration added. The XLR cable had a good 10-15m length. In quieter environments, most perturbations, however, came of bad communications and rickety mini-jack plugs.
Antwort von srone:
@ Mov
please you read through the above posted wikipedia Supplement, in order to really understand the balanced signal transmission, it is imperative that the sender sent a symmetrical signal, since otherwise the interference elimination does not work.

Antwort von domain:
It depends on whether the signal is designed to jack cable to the short yet really developed and symmetrical. Only such an adapter, make sense, but are about 10 times more expensive than conventional adapter.

Antwort von Alf_300:
Certainly something like gibts da Isolation Transformers
Antwort von mov:
No, it is technically necessary only that the impedance is symmetrical. Whether that signal lies on one or two cores plays no role in the CMMR that acts only on the output level.
For example, if 1V + ln (equivalent signal) and 0V to-ln (equivalent concern no signal), it follows that an output signal of 1V. However, if on each ln + ln and-answer 1V, the output voltage is 0V.
That is, if the 1st Added case is still on both cores of an interfering signal is 0.7V, the output is still 1V.
See: basics of OP AMP.
The following transformer of Neutrik s.der Camera would realize a symmetrical signal transmission.

Of the only link you posted refers to a balanced configuration cable, stereo klinken laicité not unusual in the large (6.3 mm), not as a stereo, rather than symmetrical (also 3-pole [pos, neg, ground]) use a adapter is not.

it just the two cores have to be guided to the source, since interference still be included s.beiden veins, and can thus be removed from the receiver.

SRON not flat, it is enough that is placed directly in front of the line to Quellgeraet the cold mass to all noise, the hide will be absorbed by the cable.
Back relating to: How a cable, I would always accompany you in your camera bag, only if noise is too high (EMC), is an isolation transformer is advisable. As a rule, but the room, the mess Akoustik stronger than the cable.
Attention, the mini-jack cable is wired properly, however. If everyone simply pin XLR on the respective pins of the mini-jack is used, takes the camera when connected to a real symmetric signal (eg, dynamic micro XLR) on the left channel signal from the Phaseninvertierte right signal, ie Monoschaltung leaves only the noise And a faint, s chlechtes signal uebrig. (Yes, by inverting the sum and one channel can be compressed in the editing program, the same effect making top, like a transformer)
Correctly, the adapter cable must be wired as follows:
XLR pin 1 and 3 to ground, and Ring 2 on top of the mini plug. Thus, the signal of the microphones is recorded on two mono channels.

http://lvptools.blogspot.com/2008/04/new-juicedlink-cx211-xlr-adapter.html 'Only' is not entirely true, a Audiouebertrager (Neutrik NA2F-J-TX) converts the unbalanced input of the camera in a symmetrical (s.dem transformer, of course). More is not required here.
The Juicedlink is a very good preamplifier (use THAT) 1512 preamplifier IC with very high Stoergeraeuschrejektions, but is more than just a Balanced Receiver.
The Juicedlink has the decisive advantage that by its relatively high output signal from the preamplifier is not usually bad the camera have to be turned up so high and therefore the background noise is low, especially for very faint sources.

SRON In Soundtrack Pro, there is an option to "Invert". I have not tried it yet, but would take it demnaechst once.

For the purpose of synonymous ideal of "ART USB Dual Pre," only just significantly cheaper than juicedlink or Beachtek.
The only drawback is that there is no tripod mount is available.
