Infoseite // Microphones and / or directional microphone ... but how?



Frage von Ayhan79:


Hi Folks,

I am just beginning to realize some projects and I would like to acquire the necessary know-how from a technical point of view. It would be kind of scary to you, if you could possibly give me some tips.

It's like this:

) In our TV Project (for a Turkish channel will be comedy sketches and turning. This will take place primarily in closed spaces. We shoot with the VX2100E so would ensure miss a good picture.

The only question now arises as to how it is with the sound. I have thought to include the sound possibly with a directional microphone (Sennheiser MKE 300 or HAMA RMZ-10) s.der Angel. But if there were microphones might be the better choice? What do you think?

Next problem: The directional microphone is plugged s.The Cam. That's good times and easy. But what's with the microphones? How to do this technically? Where do I connect it? Transmitter and receiver ... which is then stored the sound?

At this point, I need your advice Thank you in advance ....

Greeting

Ayhan

Antwort von mdb:

Whether it can be fished, of course, depends on the rotation. The sound man has to stop getting a chance with his Micro dranzukommen without being in the picture too. In accordance with pre-planned productions, which are rotated in different takes and s.festen places that should be possible.

If you want to use several badges, one has a corresponding number of wireless equipment and have a mixer for mixing. And of course again the sound engineer who mixes. And you just always have the badge in the Picture.

Antwort von Axel:

Hi Ayhan,
do you want to catch the sound, other mics are better because of the long pathway, namely those with XLR connectors. Again, this can be - or do not result mixer - via adapter to the mic in your VX. Approximately XLR> 6.3 jack> 3.5 jack. This direction is straightforward, while you have to reckon with Störbrummen if the reverse is inserted.
Ansteckmikros - they can hide, depending on the size - and the best receiver you can rent. There are cheap, such as of Shure, and less favorable, as Sennheiser. With 30 ¬ a day you have to count on each case.
At a depth of 300 reporting situations, the MKE all. When fishing or plug in game scenes were better. It is advisable to entrust the sounds to a sound engineer and aufzuzeichen him then possibly external, such as:

http://www.m-audio.de/microtrack.htm

A truly optimal starting position did you play only for scenes where you can record all sound sources separately. This will be difficult for many budgets. In any case, dialogue sources should not interfere with background noise. Sooner or later, would be synonymous to the purchase or consider yourself one XLR adapter for your Cam. At this point I wanted to give you a link to a DIY guide, but even find it anymore. Can someone help out us?

A simple cable adapter of XLR (balanced) by Jack (unbalanced) makes the entire signal path unbalanced, so synonymous the XLR cable. It does not matter in what direction are adapted XLR and TRS. ;-)

I would recommend synonymous XLR microphones to go beginning of electromagnetic interference from the road. Which may allow any addition to the sound synonymous to spoil the whole mood. ;-)

Yes, sorry, that was misleading. But it is not better in practice to bridge a longer route via an XLR cable, synonymous only if s.Schluss mic stands in an unregulated input (???) available? Do you mean with "A simple cable adapter" that there are more sophisticated synonymous, which account for an asymmetric a symmetric mono-stereo connection?

In another article focuses on the use of a stereo jack as a symmetric time:

"Forrest" wrote: You can * easily * XLR to stereo jack convert. XLR is three-wire, stereo plugs synonymous. There's also schonmal no problem at all.

But why is there no regular mono microphone with mini-jack? Do these adapter boxes actually symmetrical two mono signals through a standard stereo mic in?

http://www.beachtek.com/dxa4.html

...- No preference for how clean the signal was leaving the box (through the short stretch of asymmetric line?) It would be so exposed to all the problems, if it really did not matter whether the pathway used to be symmetrical, as long as he s.Schluß but it is asymmetrical. There was this adapter a very detailed and explicit instruction manual, which was linked on this forum. Unfortunately, I find it no longer ...

I am not lesefaul, very begrifsstutzig in electronic things. Probably I am not the only one who would take advantage of a clarification. That times have you in advance.

Antwort von Ayhan79:

Hello mdb, Axel, and Mark again Axel,

I thank you very much for the explanation and the tips!

Well, with all probability I shall sound, at first take, with a directional microphone. For this I have decided for the Hama RMZ-10. It is convenient, and besides, I have about this microphone as far heard nothing negative or read.

The alternative via microphone, mixers, etc., at the moment, probably even more complicated and calls for a sound specialist. It still is beyond my capabilities.

However: In a post - I think it was one of Axel - I've read about the possibility of microphones set up on the best way:

Lavalier + MD portable audio recorder (or other audio recorder?)

I guess that would be very economical, but high synonymous? What should I look? Can you tell me something about this variant? What kind of cheap devices can I use? What is more important for the quality: lavalier or handheld recorder?

Thanks ....

Greeting

Ayhan

Hello Ayhan.
It was like this: A friend of me had two for about ten years old Sennheiser microphones without any accessories. He thought nachzukaufen over time on ebay. But either it was too expensive or available only in the set, so he sold the mics themselves recently. The problem is that you have during the scene in MD recorders have no control (if hidden in the pocket like a radio micro-transmitter can disqualify) and synonymous only a very general and imprecise, leaving me those things only use for archiving. The M audio portion and the idea with the XLR adapter is therefore my future plans. I'm in the same period of orientation as you

That is correct. You transmit audio signals (microphone / line) is symmetric, then electromagnetic interference to be physically eliminated. How exactly this will work on Movie-Collegewww.2sound.de (DI-Box - a mystery?) Is described.

"Axel" wrote: Do you mean with "A simple cable adapter" that there are more sophisticated synonymous ,...?
Yes, there is such a clever adapter. You receive the balanced signal and convert it into an unbalanced, without the benefit of symmterischen signal range would be destroyed. You have with Beachtek (so called) is already a potential supplier of such adapter. ;-)

The transmission reliability of the 3.5 mm jack does not meet the demands of professional users. Put a time in a 3.5mm headphones jack and move (turn) the easy times. Immediately you hear a clear crackle and pops. This happens with the 6.3 mm jack with XLR and had significantly less at all.

In addition, the 3.5 mm jack provides for ordinary and not locking the connection would hardly be able to keep synonymous only one meter microphone cable (for example, if a cable without additional mounting hangs down from the microphone stand). The times would slip even at low load easily from the socket. ;-)

"Axel" wrote: ...- No preference for how clean the signal was leaving the box (through the short stretch of asymmetric line?) It would be so exposed to all the problems ...
That is correct, but does the influence of electromagnetic interference with the cable length dramatically. Holding the unbalanced signal line briefly, then keep the disturbances synonymous within narrow limits (usually inaudible).

Antwort von Axel:

Hello Mark!
Thanks for the detailed answer. I now believe that the acquisition offers such an adapter to an audio disk recorder as a real alternative, not only because of the lower price.
