Soliloqueen's k87(k67) and k47 capsules

[FetMe?FetU!]

Soliloqueen, congratulations on Arienne Audio! I am new to the forum and have to say I am just so caught up reading the thread about your journey. I have not made my way from 1 to 101, but I am more than two-thirds of the way through the forum's 101 pages (and counting) thread. I genuinely find it an interesting and exciting journey you have embarked on. It's a good read and inspiring.

I have searched the forum to see if anyone has placed a 3-pattern Flat47 in a Kingkorg-modded Perception or P 400 series microphone. Perhaps even Kingkorg has some thoughts on this? I have a KK modded P420 and an original configuration Perception 400, and I must confess I am curious what they would sound like with this new capsule swapped in.

The P420 is designed to have a K87 type capsule it it (U87 clone circuit), a K47 would sound rather dull.

... But why?

The Perception/P 2xx/4xx are designed for capsules that have a bump in the sensitivity around 10KHz, which the K47 does not. You'd probably want to mod it the other way, to roll the highs off less rather than more, or more likely, just use a mic with a circuit that has flat frequency response.

(I think I asked about whether it would work to just remove the relevant capacitor, or replace it with a lower valued one, but I now I forget what the answer was. And as for why, it's because I have several of them lying around and they have proper pad and high pass switches, which the flat-circuit mics I have lying around don't.)

So, do you think the Arienne Audio K87 is the better choice since it designed the circuit in my microphone? It would be more expensive, and it looks like I would only have one polar pattern, which AA lists as "normal," which I guess is cardioid.

I like the Kingkorg mod results with the stock capsule, so the question is, will the AA capsule be a dramatic improvement over the stock one?

no, they just have better side to side matching, so there's no need to sort them. They are all multipattern

Oh, thank you for clarifying. That makes much more sense. I'm from the video side of the business and have only recently been expanding my much-neglected audio knowledge. I'm finding microphones remarkably and disturbingly addictive. They're easily as costly as video gear—microphones, that is. Not your capsules, which appear to be quite the value for the performance they provide.

I wouldn't expect a dramatic improvement, because the Takstar capsules in the Perception/P 2xx/4xx are actually pretty good, and shockingly good for the price. (Which is why kingkorg's simple mod of a cheap mic is so awesome.)

The Arienne Audio capsules are manufactured & quality controlled to even higher standards, for sticklers for high-end components, which I'm mostly not.

I personally opted to keep the Takstar capsules in three of my Perceptions, and they seem fine. I'm told that there are no similarly cheap but good-quality K47 type capsules, comparable the K67/K87s from Takstar and Beijing 797 Audio. (Apparently most copies out there are a bit screwed up because people don't understand what they're supposed to be copying, as Arienne does.) So I bought an Arienne Audio flat 47, and plan to buy a vintage accurate 47 as well.

 

[soliloqueen]

most of the remaining differences in a p420 are acoustic tbh. I don't think buying one of my capsules would provide a massive improvement. Minor maybe.

 

[FetMe?FetU!]

I appreciate your honest assessment. I will look for a PCB or a donor microphone that works best with a Flat47 and go from there. Thanks, soliloqueen and everyone who replied.

 

[FetMe?FetU!]

I will be ordering a Flat47. I just have to move a few investments around to free up some capital. Sell some blood or spinal fluid.
