Frage von WWJD:
Hi sound crew
I recently got myself a good Field - Mixer - Mirkrofon equipment for captured video. purchased, see above.
But unfortunately I'm now a few bad experience with specific recording situation. Specifically gesgt at musical performances on stage.
The recordings are always slightly distorted, although the mixer and s.der Cam (Canon HV20/30) max. -15db was leveled.
What do I do just wrong, I'm s.Ende Latin. When read by a spokesman for his musical performance text, the sound is absolutely fine, just distorted by the whole music. Do I need another maybe a microphone, and if so which one?
Am very grateful for your help.
Best regards
Jack
Antwort von ruessel:
Maximum sound pressure exceeded? Enough phantom power?
Antwort von WWJD:
I now always with the Micro uses a 1.5 V battery, not with phantom power. Is it possibly that?
Where can I set the max. Sound pressure one, and which settings are to make the blender?
Antwort von ruessel:
Is it possibly that? 100% YES.
Antwort von WWJD:
Okay ruessel that it would try it.
Thank you .........

@ Ruessel:
Can you explain that? Supposed to mean that the micro with a 1.5 volt battery works differently with 48V of a mixer?
Thanks and regards,
nahmo

At the limit, clearly YES.
For the normal output, it is completely no preference, you take what operating voltage within the predetermined normal values. Bandwidth and distortion of them are almost independent. But the maximum achievable. Output voltage of the microphone and some synonymous changes the impedance, ie, for maximum volume I need synonymous max. Supply voltage, otherwise the signal peaks are no longer rich and are just flat ....... then it drags.
In my example, can be mapped with catchy 1.2V normal road noise well, with 9-10V has a lance stretcher with faulty exhaust .... without which it pulls.
Antwort von domain:
Normally and in good mics the 1.5 V AA-Baterie but are not used as phantom power, but before that brought by a voltage converter to substantially higher values, such as 48V.
The quality of the generated DC voltage beeinfusst but significantly the quality of the output signal.

Antwort von domain:
Quote from the website:
"Battery power:
In the non-or semi-professional, such as using unbalanced inputs of a mobile recorder, an usually battery-operated powering into the microphone cable to be connected to the power supply, if the condenser microphone such powering integrated in the handle itself has not. This bias is the with a voltage converter from the 1.5 volts of a commercial battery won. The quality of the obtained DC voltage has a direct effect on the microphone signal quality. As the power needs of a condenser microphone is very small, battery holds a lot of hours before. " This is true only for microphones, which are generally dependent on phantom power.
Antwort von ruessel:
Such a voltage converter I have ever seen, they usually run only s.ca. 4V going on. Also, all the microphones I've opened so far, had not synonymous no voltage converter, the Rode. Only my Sennheiser wireless transmitter makes it s.der microphone jack and runs synonymous with more batteries.
This is true only for microphones, which are generally dependent on phantom power. Right, like I went out ....

In other words, with the 9V my RODE STEREO RODVIDEOMIC s.der HV-20 as I lie on the secure page, such as with the XH-A1 connected s.Phantomspannung the Sennheiser ME66 with K6?
but not with the operation of the Sennheiser s.meiner HV-20 and then with battery operated 1.5 V?
Antwort von ruessel:
In other words, with the 9V my RODE STEREO RODVIDEOMIC s.der HV-20 as I lie on the secure page, such as with the XH-A1 connected s.Phantomspannung the Sennheiser ME66 with K6? Non-auto. Tonkapsel with a 48V can scratch if it is good nothing. Supposedly synonymous age, the conventional electret microphones, you can hear that, the Sennheiser (ME) from the 70/80er years already strongly diminished in the sound.
Antwort von nicecam:
Then I'd best hope then that my (used) has not only andenes ME66 many years under their belts. 70/80er years may not be so, then it could have a lower number, I suppose.
I read once synonymous, that the connection between the power supply modules and the microphone part is critical in aging. That would speak so again for a Rode NTG, which represents both a unity.
Antwort von ruessel:
I have the NTG3. However, I hear little difference to NTG1 / 2 out ..... synonymous, the signal quality is not the same (noise), only the levels.
Antwort von domain:
Today's conventional electret condenser microphones need because of the permanent electrostatic polarization due to no more phantom power, synonymous if they can run on one. But they need at least 1.5 V for other adjustments electronics, such as an impedance converter or a FET amplifier, both already integrated into the Mikrokfonkapsel.
In the case of course no longer up voltage conversion to be carried out in the direction of phantom power.
One can therefore speak of in these cases no longer a need phantom power as such.
Antwort von WWJD:
Ohlala because my thread has caused what.
Your shop talk me now a little confused people.
What is now in my case?
Microphone battery out and only work with phantom power?
However, thank you for your input ;-)
Antwort von ruessel:
Microphone battery out and only work with phantom power?
when it is noisy, yes ....
Antwort von thos-berlin:
There is still the possibility that the maximum sound pressure (Russel see first post) was exceeded.
If initiated by the loud recording situation, the membranes s.ihre mechanical limits, sounds synonymous with down regulated audio control distorts the signal. This has nothing to do with dan the supply voltage, since not change the mechanical limits.
Perhaps you will help
this thread
in noisy environments, a dynamic microphone avoid Maybe.
Antwort von domain:
I would say synonymous, but in theory it should make no difference electret. If it is the music on stage but to act very loud amp music, then I'd bet more on noise levels that the micro simply overwhelming, especially if then the softer language sounds normal again.
levels in the case, namely you can with what you like the music, synonymous to -20 DB and will not notice any improvement.
Antwort von nahmo:
I thank synonymous for now.
Greetings,

Antwort von ruessel:
If initiated by the loud recording situation, the membranes s.ihre mechanical limits Rode NTG2 = 131dB
Antwort von thos-berlin:
Rode NTG2 = 131dB To permanent damage to or distortion?
Antwort von ruessel:
SPL = 131 dB (decibels sound pressure level) SPL at microphone NTG2 measured distance of 1 meter at 1 kHz - THD is s.dem of greater than 0.5%.
Antwort von nicecam:
Permanent damage to ... Those are the fears that get all the one.
Did all times just google urgently need now:
maximaler Schalldruck and die Möglichkeit of BeschädigungIch positionierte mal (in meinem immer noch währenden jugendlichen Leichtsinn) mein ME66 - sagen wir mal 1m vor einem Bühnenlautsprecher and hörte Music über Headphones ab. Au, Au - Aua,
THAT was loud. I was down to levels close to 0 - was still distorted. Then I tried it with my micro dynamic, that was then.
Now nicecam help but to thos-berlin and out of their misery is because now my damaged ME66? : '- (
Oh, I do not think times. Still takes decent altogether. : '-)
Antwort von mbwkrause:
After my experience, the NTG-2 sensitive, especially in the bass regions and tend to overload there earlier. For live music, it is plain and simply wrong Micro, for everything else there is in the price range (almost) none.
