Infoseite // Why camera spark gap is 5-10 times more than stationary equipment?



Frage von ArnAuge:


Good morning,

have no experience in the field, unfortunately, synonymous in the forum and have found nothing. So sorry if I play the fool ask:

is a wireless system with lavalier microphone, bodypack transmitter and 9.5 "receiver's 100-net already in euros.

Why are the plants with a mobile receiver for the Camera 5-cost 10 times as much? Depends only together with the number of units sold? Is it possible and useful to convert a low inpatient facility on mobile?

For scenic work from the Tripod should anyway but nothing to the contrary, the box (evt with power supply) to mount the cam - or is it?

Antwort von MUK:

Good question - the same question I've already made synonymous.
I have to answer Ne unfortunately not synonymous.

've ever ELV of a small spark gap with purchased two mobile (transmitter / receiver - Lav-Micro test for the 40 euro to the.

Funtioniert synonymous somewhat. However, p.5 m distance, the whole becomes susceptible to breakdown. through walls is nothing.

Antwort von ArnAuge:

Stationary plants are actually meant for the stage, so in an environment with particularly many potential interferences (amplifier systems, lights, hydraulic cranes, etc.)

A mobile radio link must still work in such an environment synonymous nor fail-safe, but that applies equally synonymous for the cheap stationary.

Perhaps there is still someone who has an answer.

Your EFT facility was a kit?

Antwort von MUK:

No, the ELV - was not part of a kit. However, the transmitter-receiver cheapest plastic housing and the antennas are pure käbelchen thin.

Antwort von beiti:

As everywhere, there are synonymous in the field of radio links different quality classes. There are facilities for 100 euros and those around 1000 euros or more.
In a 100-euro plant may be set then neither reach nor s.die s.die equipment (such as frequency selection) nor s.die special reliability requirements. Who extensive stage technology with potential sources of interference will have to buy not even a cheap system. For single non-critical applications (such as solo in the nursing home, etc.) but it may suffice.

Comparing high-quality sites (eg of Sennheiser), are those designed for stationary use and those designed for mobile use at a similar price level.
The same applies in principle to Billiganlagen, however, be more facilities for stage purposes in demand, so that here the offer s.Billiggeräten greater.

Antwort von ArnAuge:

I imagine now the question again the other way: Is this price difference justified only marketingmäßig or are there for solid technical reasons? Has possibly with the frequencies used to do?

Thanks in advance!
Arno

Beiti Hello, thank you! Now you are come to me before :-)

After the argument would have to be even cheaper mobile equipment ...

Mobile systems also need a Battery. In addition, these radio sets are used mostly of professionals, so high quality products are built to be fast expensive.

And on stage? Yes, but since everyone uses a small club cheap radio system from China without imposing requirements s.die quality. And if it then rustles, there is no preference synonymous, because the music usually is not as good synonymous ;-)

Unfortunately I have such cheap versions for cameras (also mobile with Battery) is not known.

Greetings!

Antwort von ArnAuge:

Thank you, so it gets even clearer. In my particular case, ity's perhaps a simpler solution (the actor says in the wild in the country interesting facts about horticulture). But in the long term is surely worth an investment in higher value what.

I have the right in an earlier post to understand that generally the G3 / E-tape is future proof?

Antwort von beiti:

Besides the above ELV system, there was a time of Samson (with a very small receiver that could be put on the hot shoe). but both have disappeared from the market, that has to do perhaps with the new spectrum policies in Europe.

In the U.S. there are still some, but its operation would be banned very likely with us.

Did you this? http://www.bhphotovideo.com/c/buy/Wireless-Systems/ci/15419/N/4291086004

Here's systems for $ 149 and the optical do not approve impression. Can we use here, but probably not? - Really annoying!

Now the Yanks have been in the software always the price advantage ...

Ahem, perhaps you should take care that no BGS helicopter is near ;-) (because of the BGS VIP frequency that is probably as synonymous still in there)

Antwort von Paul*Berlin:

So what is speaking against the use of a stationary system, is that somewhere you of current need. Whether this is a battery-pack, your car battery or an extension of is the closest house to me is no preference. Only you need something like this, It could not be otherwise. :)
But then it goes. Only then one is always bound s.Strom.

I have considered the following (but not to "research"): When use the transmitter for Stationary equipment and the receiver for wireless in-ear monitoring the same frequency range, you could theoretically collect it and use something, right? I am but at times that the bands are different in order to avoid feedback, etc. ...

Antwort von thos-berlin:

Same Frequntbereich, but "InEarMonitoring sends stereo. What do you want with the remaining two stationary devices?

Space


Antwort von Paul*Berlin:

I know, there are synonymous mono-in-Earing plants. Can I say pretty sure because I have ever thought to get to concerts and events to such a device, then the sound directly into the action and have me still can freely move of wires. But since my budget is limited, I had to realize that the best versions are mono. For concert or transport possible but I would just like to use stereo. The man could then use to use it.

And the remaining stationary devices I would use s.aufheben and if necessary, if no spark of "on battery" to "on battery" is necessary. When you're at an event, you could press so as the speaker wireless microphone in hand (if there are no radio mics), this signal is sent to nem stationary mixer, there with atmosphere or other mics mixed, and of there again by radio to the camera (then you only have to set another frequency ne: D) or b) try to sell the parts. Perhaps even time someone broke something like that, and need something. But is rather unlikely:) but that is rather a variant).

If you need the sound is not live, synonymous a separate sound recording would be considered, that is a small mobile recorder in combination with a lavalier microphone.

Antwort von WoWu:

Paul @ * Berlin

With the 2x mono 1 = stereo you have to be careful, because can have different latencies of the individual devices. The Falls at 2x not use Mono, but if you want to do MS stereo so that, already rich tiny variations, to shift the phase so that you have in Monobild almost nothing more.
This is wrong in some circumstances.

Space


Antwort von Paul*Berlin:

Hello Wolfgang,
I understand only station to be honest!
post them with the idea of two monoses s.einen stereo receiver, I have honestly never played (Okay, yes, but only 5 seconds). Either can send a monoses s.einen Monoempfänger (for "on battery") or the stationary s.den stereo stereo receiver "on battery".

And if you only need mono from a micro, but you can theoretically synonymous record only on L or R and drag it into the postproduction on beie channels, right?

Best regards,
Paul

Antwort von Blackeagle123:

ne car and buy yourself using one of these Billigteile for stages. Then only need a cheap adapter for AC, which you get for under 50 ¬ for the cigarette lighter, 150 Watt maximum. Can synonymous abandon the car and put the receiver in your car check-(but that your car anspringt after that ;-))

So you have a huge home-Battery ... Is of course nothing for EB-shoots, which should properly be mobile. But ne for such an exception alternative.

But I would rather invest more and sell the adapter, then ... (For example s.mich ;-))

Greetings

Antwort von WoWu:

Paul, sorry, had I understood this wrong.
Sure, you can easily Stereofeed the move to Mono ... and just lay on both synonymous 1xmono Stereokanöle.
I had only understood that you wanted to add two (independent) monoses in the camera as a stereo signal. That would be difficult. But if it is not it, all right, all wrong.
Greetings to Berlin
