Hi everybody!
Once in this forum the vexatious issue constantly circulates and Microphone phantom power, I would like once more to all seeking post here as I have resolved the matter:
I work with the
Canon XL1s and the
MA-100 adapter (2x XLR large). Said adapter has
no built-in phantom power, so I needed an external. And I think I've found a solution that fits in the price-performance ratio:
At AKG, there is a
two 9V blocks operated with 48V phantom power for a microphone. That should suffice as a rule, for example, if you like me a (mono-) shotgun microphone used. The beauty s.der Solution: You're here with 100 euros and the brand with high quality components!
The aforesaid is called phantom power
AKG B 18 and is about
103 euros www.musik-produktiv.s.um available.
Incidentally, I use the Thomann T. BONE EM9900, which provides for only 99 euros very good quality. (Www.thomann.de) - So all together with an indicative micro with 48V phantom power for $ 200! - I find really OK!
Edit by voller_mond: The AKG B 18 supplies only 18 volts and not 48 volts!
Maybe I've helped one or another Canon XL1 / XL1s - Users with my short, of course, as all others who use a camera with XLR connectors, but with no phantom power.

is that the adapter only supplies 18 volt phantom power. For some microphones which no preference, but some will rush a little more. There are synonymous microphones that absolutely need 48 Volts.
Does anybody know how the example in the Pro versions of Sony's camcorder? Provide genuine 48 volt or synonymous as a compromise?
Antwort von ruessel:
Sonybenutzt in its XLR cameras such as the A1, the IC-voltage transformation .... thus becomes of the low camera battery voltage 48 volts but true .... only with a few mA to straining, but reaches nearly every modern condenser microphone.
Antwort von beiti:
What is s.einem castes such as the B 18 in fact technically true? Phantom power is needed for an expensive electronics, or you could cobble together such an adapter synonymous yourself?
I was thinking, for example s.eine variant with 5 9-V block, which would then deliver without major transformation of a stable 45 volts.

Hello!
Next s.Beiti Thanks to its correction, in fact, the AKG B 18, only 18 volts, that was my mistake.
The topic "What is phantom power s.einer really true?" I would say: Not much! Essentially, two capacitors and two resistors, although of course it is synonymous a question of quality of the components themselves - if you're an experienced hobbyist or radio Schuster You ought to have no problems Gober.
In the Appendix I have added a circuit diagram of a phantom power. This is the cheapest of phantom power of www.thomann.de.

Antwort von beiti:
Thanks for the schematic, if the synonymous disclose itself to me not right (not to mention the fact that no value data are available for the components). I'm not an electronics engineer, but when the two parts will be up resistors, then I do not understand the technical end.
The use of capacitors sense to me (isolated), but the problem is likely to be synonymous, because depending on the quality of those things certainly have influence on the sound quality.
But I do not come due to your left is a completely different idea: Since the unit of Thomann working with DC and is very cheap, we could perhaps take apart and rebuild to battery.

But I do not come due to your left is a completely different idea: Since the unit of Thomann working with DC and is very cheap, we could perhaps take apart and rebuild to battery. Yes, I have brought you synonymous with the exchange something I ordered the unit from Thomann already, because it has an external power supply and is powered by 12 volts DC of the outside! Then I came to a very similar idea as you! I do not need only 8 pieces 1.5 Volt AA Batteries in series and had to depend on 12 volts! And if I do I do with Batteries can operate the device so long synonymous!
... And I Schwups synonymous with a 48-volt phantom power! :) ... how it will work we'll see - this means it now and wait to try! :)

I'm curious to your experiences!
Antwort von voller_mond:
Hi!
Late but still, here is a small report on the experience of self-made phantom power: I have hung ten o'clock in series with 1.2-volt batteries instead of a power supply my phantom power (thomann.de, supplies 35 euros). The whole I carry in a small waist bag with me and it works just fine - with a convenient alternative to the security XL1s equip with a phantom power.

Good to know. ;)
Have you been synonymous Erfahrunswerte, considers how long a battery charge?

Have you been synonymous Erfahrunswerte, considers how long a battery charge? In short, FOREVER!
The power consumption is so minimal and I dine s.with 10 in the series hangers 2300mAh 1.2V Batteries ... on the battery you need when you do not worry, because you go before the 10 DV tapes you made in your case with you wearing? ;)
