JLI-3412

 

has anyone tried the JLI-3412 yet?

If so how does it compare to the 2555B or other well known capsules?
 

I suspect most of the FETless electrets of this type of construction are simply variations of the Chinese ones like this:?
which are often actually quite good. Usually a bit noisier than 34mm? non electret? LDC capsules, but not too bad.

The JLI data sheets don't help much, they're just mostly 'copy and paste' nonsense? ?(2k2ohm 'impedance' for a FETless electret?? )
Some electrets with that kind of backplate structure have grills across the front - some not.? Those that I've had from Aliexpress don't sound too bad.
Certainly very good value for money.....

The 3412 is bigger than those brass 25mm capsules.

I have some of the brass ones and they do sound reasonably good (especially for ?3), but they have quite a pronounced peak around 10k - so there's a fizzy zingy sort of edge to the otherwise balanced tone.

The 2555B is well liked on this list (I don't have one) and by all accounts better than those ubiquitous brass 25mm capsules.

I am hoping the 3412 has a balanced tone similar to the 2555b rather than the zingy tone of the generic brass ones.

I have tried it. It does not have a pronounced peak. I actually like the TSB2555B better as an all around go to mic.

I hadn't noticed that the 3412? was a 34mm capsule -- my mistake - sorry about that.
I hadn't thought about trying one. They are more expensive than the 34mm LDC I'm using at present ( ) which I've found to be pretty good.
Those are certainly less noisy, and have a better overall frequency response than any of the electrets I've tried so far.

I can see how the 16mm or 25mm electrets might be more suitable where it is not feasible to include 34mm capsules -- in multi capsule mics for example.
And there is of course a voltage multiplier to find room for, with externally polarised condenser mics..... Again, not always a sensible option.

As for EQ adjustments, I'm not a fan of adding passive EQ into the mic itself, to try and overcome the peaks and 'zing' of some of these capsules.
I prefer to either add any required EQ in post - for recordings - or do it at line level in my channel strip for real time live requirements. Better options to apply any EQ more precisely.
(Some notes on that project? ).

I have quite a few edge terminated externally polarised dual diaphragm capsules of various flavours, chinese and otherwise, including one that may be the same as in your link (though I haven't tried that one yet).

All the chinese edge terminated LDC capsules mostly tend to being rather bright, but they also vary a lot between sellers/manufacturers, while looking almost the same externally.

I'm interested in a single diaphragm large capsule like the 3412 as I haven't got any of those and they may respond differently from the ones that have a skin both sides, especially in the bass.

As far as frequency response goes a decent 6mm electret is usually flatter than any chinese LDC - but of course that's not the only criteria.

The chinese LDCs mostly seem to roll off fairly rapidly below 60hz or even higher.

There's no reason I know of why an electret should be noisier than an externally polarised capsule if they are the same size. Since the electret polarisation tends to be more extreme than usually applied externally they may even work out quieter.

Thanks, Do you have any other impressions? How does it differ in sound from the 2555B?

Does it have more bass extension?

The 3412 has more bass and/or more proximity than the TSB-2555; the 2555 is actually somewhat thin on the bottom end as compared to LDCs. The 3412 flatter on top than the 2555, but the response falls aggressively above 10kHz. There’s no “air.” My initial impression is that it would be better suited to a voice/announcement mic than to music.?

As you say, no intrinsic reason for an electret to be noisier than a 'standard' condenser... I think I may have confused the issue by comparing? a 25mm electret with a 34mm LDC.
Slight case of my comparing 'apples with oranges' there - sorry about that!
 

Agree with Matt... to my ears, 3412 sounds darker, kind?of similar to some K47 style capsules.

Kind regards

Agree with Matt as well. Also more sensitive to plosives but that’s an edge terminated thing. It’s the falling off at 10k that deterred me.?

thanks for the description Matt!

sounds quite interesting - could be good for kick drum front head micing if it can handle the level /air movement.

lack of air in the top would be a problem for general use, but might actually complement other mics I have if the bass can do things they can't.

Hmmm ... perhaps it would be more useful in some limited, specialized applications, such as voice over narrations, audio books, computer speech recognition, paging, and other voice-only applications where a full frequency range is neither necessary nor advised? Consider, perhaps, ham radio transceivers which employ a quite limited (200 - 3000Hz) frequency range - a mere portion of the human speech frequency spectrum. In such cases, the limited response curve serves as an ersatz brick wall low pass filter of sorts. Shure makes the Model 522 communications microphone with a limited frequency range "tailored for speech communications" and it is especially intended for noisy environments such as dispatch centers, restaurant and other public venue paging, ham radio, and similar noisy venues. In other words, one way to minimize noise in your application is to use a microphone that cannot capture it in the first instance. After all, microphones are used in a great variety of situations, not just recording studios.

Any traction? JHR
