AKG 414 question |
|
|
how good is the null in figure-8 setting on this mic?
is there another mic in this price/quality range other than a ribbon
mic that has a better null?

Its pretty complete. Another one to consider is the KM120, which has
excellent sound and null. |

Do not forget the wonderful figure-of-eight
microphone of Schoeps
http://www.sonicsense.com/schoeps.htm
Look at CMC-6 body and MK-8
figure-of-eight capsule.
Super null and extraordinary sound.

Which mike? There are three different capsules used in the 414 series.
The 414B/ULS has an excellent null. I do not know about the TLII, or
about the older EB.

Any well-made large dual-diaphragm condenser will tend to have a good
null, though it depends on how carefully the two diaphragms are tensioned
to be identical. The U87 is another popular thing.

What exactly does "null" mean wheb referring to mics?

It's the side of the mic that is least sensitive to sound. On a cardiod
mic, the null is 180 degrees from the front. On a hypercardiod, there
are 2 nulls, closer to 150 degrees. A bidirectional mic has it's nulls
at 90 degrees from the front and back. And an omni doesn't have nulls.

Albert, that's a nice explanation. Just one note: In a classic
hypercardioid pattern (0.25 + 0.75 cos theta) the null is actually 110
degrees in any direction from the main axis--three-dimensional, of
course--while with a classic supercardioid (ca. 0.37 + 0.63 cos theta)
the null would be around 126 degrees, except that no manufacturer today
to my knowledge actually makes such a microphone or capsule.
Even most condenser microphones that are called "hypercardioid" and the
"hypercardioid" settings of most multi-pattern condensers are somewhere
between hypercardioid and supercardioid, with their nulls at around 120
degrees. This includes the Schoeps MK 41 capsule and, if I'm not
mistaken, all Neumann condensers.
A generation or more ago the Schoeps MK 41 was closer to a
hypercardioid, but they made some adjustments in the mid-1970s around
the time the Colette series was introduced, bringing it across the
mid-line. The U.S. distributor started calling it a supercardioid and
Schoeps decided that they agreed with him, so they changed the
designation. But it was never really either of the "classic" patterns
exactly--it's what sounds best and works best for the customers.

It's null and void. |

So any 414B or TL or TL2 can be off as much as 1/2 volt which balances
the voltage presented to each half of the capsule.

Hi Jim,
What's the story on the 414EB P48? I know that the circuit was changed
a lot from the 414EB. But there were claims from AKG that it was
a quieter mic. But then I know some people believe that they actually
took out the DC-DC converter (since it has to have 48VDC and not
the old range of 9-50VDC). This would mean that the polarising
voltage is only 48V so I would think that would lead to a noisier
mic.
Any insights?

Before the FET, it's a shunt cap.

Oops, yes I meant microphone preamps.

about that, go ahead...). He sees building a 62V phantom supply that
feeds
the capsule (and output electronics) directly is a way to eliminate the
blocking caps and everythings gets a little better. Basically, now, it
means that your 414EB P48s (P62s!) now have their own power supply, much
like tube microphones or B&Ks.

How about a great transformer at the preamp input stage, like a Jensen?
Of course, an external power rail is always better than a Phantom or (yuk)
T-Power arrangement, but I don't think that the change will take place
anytime soon.

Right.
| Quote: | But you do lose out since there must be
a number of condensor mics that would perform a lot better if they just
came with their own power supplies with 5 conductor cables. I know it
comes down to a major pricing difference. If you have to buy a mic with
a separate power supply instead of phantom, you are going to pay at least
another $500 for it. Now who's going to pay $575 for an Apex mic?!
