Frage von ChristianR:
I have tried to use the G2 Sennheiser SKP 500 (with 48V phantom power) with one Rode NTG-3.
But, unfortunately, ever comes out no signal. At SKP 500, it can not lie, this works. Have synonymous output current and output voltage measured with phantom power switched on and everything was in order.
Did any idea what's the problem? The NTG-3 is brand new, but I have no phantom power, to try out there somewhere. But I assume that it should work. Perhaps there is another problem that lies at hand, but I do not see.
So if someone has an idea, I would be grateful.
Antwort von TobiasD:
The SKP-500 may not seem to provide enough electricity for the NTG-3. It probably takes more than some other shotgun. This statement I once found in an English-speaking forum. To be found with the first entry in Google under the term "ntg-3 skp500.
Antwort von ChristianR:
... I thought synonymous (as it did in English reading. Forum), but this is not apparently so.
Indicate is that the SKP 500 2mA supply, but the NTG-3 requires a minimum of 4.3 mA.
But I have measured the current at SKP: it delivers just 5mA. There must be somewhere else in it. Why SKP delivers significantly more power than is given to me but synonymous not clear.
The Forum was synonymous, that (the NTG-3 with the lower stream of really is not so low), not so hot "is". But for me at all is no signal. I do not understand. Perhaps the brand new Micro broken? If there is no other explanation, then I probably make me the mike on.
Antwort von TobiasD:
Have you measured the voltage while synonymous? Maybe yes, then the breaks too much.
Antwort von hofnarr:
in bedienungsanleitung to skp 500, with 48v phantom power from 2 milli amps is specified. perhaps the plug-on with the coming of rode ntg-3 milli amps handle 5 is not needed, but then some others with microscopic capacitor should also not work. precaution you should ask when sennheiser whether the SKP 500 actually only 2 milli ampere current providing dining ...

Antwort von ChristianR:
From what we can say that the tension is broken too?
Here is what I have now measured by the opening of the microphone s.den inputs: the voltage is approximately 4mA at 31V about now.
If this is a critical value, the functionality of the microphone is too restrictive (that is actually no signal)?
Antwort von hofnarr:
31 volts could be used for a "real" micro-capacitor as the ntg-3 be too little. rode there in the data sheet for 44-52 volt. I was with the ntg-3 but never problems with various phantom power sources, a skp 500 was not yet among them.
edit: you run the plug-on with normal batteries or with rechargeable batteries? when (not original) rechargeable batteries behave the sender sennheiser sometimes strange ...
Antwort von ChristianR:
I think that the problem has now been narrowed down pretty well, if not synonymous with absolute certainty that no statement can be made.
First of all, many, many thanks s.euch for the rapid and very helpful tips, without which my troubleshooting certainly would have gone nowhere.
For the time being can reasonably suppose that the SKP is overwhelmed with the Rode NTG-3.
What are my alternatives? The new Lectrosonics plug-in transmitter is more 'power' have, but it is much more expensive. The new Sennheiser SKP 2000, according to the same values (if synonymous me by the technical department of Sennheiser else was said, so in that respect here probably still a question mark).
An alternative seems to me a modification of the SKP 500 to be, what should not be too expensive, but will certainly go much at the expense of duration of use.
But I will up front the NTG-3 s.eine other 48V phantom power must dranhängen, so I can be sure that the error is not there to find, but just 500th in the combination with the SKP
Amazing that to this day still find little or no information about this set of problems on the network. Then it was high time indeed, and could help those who are faced with a corresponding purchase.
