让我们知道AB是如何出现的。“PIMPED”版本将为您带来更多的净空，并理论上较低的失真，但不确定如何听到它。我仍然与overs overs overs的争论参加了.001％的失真，一个是.00001％抱歉，你听不到...

I think they do. I'm not sure. I ordered mine in a quantity of 20 so I could do multiple builds. Then I ordered another set and they were cheaper because they had already done he validation etc. I'm not making anything on these it's just production cost. PCBWays is quite inexpensive and does small runs cheap.

谢谢！他们是伟大的麦克风。我知道国际订单等。希望PCB途中有盎司覆盖。1月我在那里，很高兴我们在Covid之前制作。将回归oist covid。我试图获得多级经销商。它们在台湾，发明了（或RediD LOL）大隔膜驻极体胶囊。你可以做焊接....享受，让我们知道它是怎么出来的！朱尔斯

Absolutely. The SSM2019's draw at the most 10ma each and the OPA2134's about the same so all in 80ma all in so you are easily covering that with 850ma

You can try contacting then directly to see if they have a European distributor. https://www.transound.com/enus/index/Additionally there are 25mm electrets on sale on ebay. I cant vouch for them though

Thanks Andrzej, There were trees in front of us and a gazebo type building to "stage right" for lack of a better term. I mixed this in Reaper with a bit of effects on her guitar, some overall compression on voice and guitar. We have a second song with different dynamics that I have to wait on posting as it is getting released on her label in November. (The song, not my specific recording of it.) I'm loving my mics and what they can do!Jules

I used a 4amp bridge in mine. The one above should be at least 1amp and 100V.

是的，这将是一个更好的词哈哈！谢谢！

除非组装整个东西，否则嗡嗡声将在那里，这提供完整的屏蔽。邻接没有连接到FET的胶囊的偏置。这将摆脱60Hz嗡嗡声。

Yea, that FET has a reverse diode built in that acts as the 1Gig resistor. Excellent!

FET是否正确连接？那个woudl赌注。

确保FET引脚排列为正确。我之前错误地焊接了它们。在一个正面票据上，我没有损坏FET。朱尔斯

这是一个缩放F6，六个输入字段记录器。它记录32位浮点数的音频。它是以原始格式拍摄图片的音频版本。https://www.zoom-na.com/products/field-video-recording/field-recording/zoom-f6-multitrack-field-recorder#specs.

绝对它与这个https://www.jlielectronics.com/microphone-cappaules/jli-165a-t/有很好的工作

Thank you

是的，恒定电流从等式中取出电源电压。MOSFET将增加其功耗

I do not have an updated design but if you keep the total impedance close i.e 6 ohms vs eight you should be fine. The current design is matched to the characteristics of the little Dayton NEO tweeters so there is more than just the impedance to think of.

The FET is acting as phase splitter. it isn't providing gain and we are pulling signals off of both "legs" of the FET. IN this case a bypass capacitor is not needed and would actually be detrimental to the circuit. The basic design here goes way back to the first solid state Schoeps microphones.

22nf用于RF干扰。在20kHz时，它们的阻抗约为350欧姆。这是在音频频率和RF的真正大的效果。470pf在20kHz时为17kohms。这些真正使电路稳定和子弹证明在嘈杂的环境中。

该问题的答案取决于您使用的LED。我用进入管道的人，密封它.jules

There are several equivalent FET's THey are getting harder to find. the P-301 and its family will work. And yes you can use a 1W 1Gig resistor. It is just larger.

丝带胶囊实际上与冷凝器胶囊相反！换句话说，冷凝器具有非常高的阻抗输出并在隔膜移动时产生电压变化。丝带是非常薄的金属片，其在磁场中移动（由于声波）。它产生了一个非常低的电压输出，需要使用大量放大。通常，它们在麦克风体中使用升压变压器作为电压增益的第一阶段。请参阅这里更多：http：//www.bumblebeepro.com/ribbon-microphone/ribb ...与之通过设计，完美图8麦克风。其中两个，你有一个blumlein对。它们也不需要幻影力量。我不确定是否有人试图在没有变压器的情况下制作活性电子带麦克风。我怀疑工作是......

If my Russian is any good (Thanks Google Translate!) My circuit is very quiet. It can be used for nature recording. My orchestra recordings easily picked up the HVAC system in the building.

你好，谢谢阅读。您可以使用相同的电路100W LED我正在使用的电路。（我已经完成了）你必须做两件事：最重要的是散热MOSFET。我正在使用T220一个，那部分应该很容易。我使用了不同的散热器比100W LED（没有真正的原因，我是如何做到的）。其次，改变了对100W LED的当前抽取的感测电阻。这些是同一基板上100W LED的阵列。他们需要3.3pmps来完成100W。然后我们的检测电阻变为.7V / 3.3安培或.212Ohms。我使用了.22，因为它们很容易获得。 OK, Now if we put 3.3 amps through a .22Ohm resistor it will dissipate about 2.5W of heat. So you need a 3W or higher .22Ohm resistor. Something like this will work: https://www.digikey.com/product-detail/en/pana…

我试着翻译这个并遇到了困难。你能用英语再问吗？

You can plug the stereo on straight into a zoom recorder. Make sure "PIP" power is on for the 1/8" inputs (Called Ext Mic on my ZoomH4N)

Sounds very nice! Thank you for posting this.

它可能是但需要更多的工作。每6英寸每6英寸为400 60W LED，如果它们是RGB，那么每个LED为3个驱动器，所以1200驱动电路和75个驱动器IC

You can use the BM700. I have built four of these using the http://www.jlielectronics.com/microphone-capsules/jli-165a-t/ capsule. And the pimped Alice circuit. That would be my recommendation.

让我听这个，我会给你带来nack。

太棒了！我想建立一个ambisonic麦克风。首先使用TSB165然后TSB-2555B感谢分享，真的很欣赏它

Well now, that sounds like a project I need to do! The simplest means would be to use an external FET and 1gig resistor and then it "becomes" an internal FET capsule. A little more complicated than that. I am in process of moving and all my stuff is not here yet. I will work on this one!Jules

感谢您的客气话。这不是构建插入3.5mm麦克风插孔的麦克风的最佳起点。这些供应5V称为PIP电源此MIC胶囊为HTTPS：//micbooster.com/primo-microphone-capsules/1 ...查看更多：https://en.wikipedia.org/wiki/elelectret_microphonejules

Absolutely that will work! All you need is clean +/- 15vdc

好的！我是SSM2019的粉丝。如果您“按照地面规则”哈哈，它确实提供了它。很高兴知道这篇文章仍然被记住！朱尔斯

Thanks for asking, That 10uF cap acts as a filter for the internal supply voltage in the original Alice circuit. In my circuit the filter is formed by the capacitors and associated resistors on either "side" of the zener.

最优秀。我很高兴听到你的成功。我喜欢这些麦克风。对你付出的东西如此好。感谢您分享您的构建.jules

Yes! The capsule I am using the TSB2555B is the sister to this one: http://www.jlielectronics.com/microphone-capsules/...Which is the one you mention. (I think) I have built a matched pair of the TSB25A

谢谢，我使用Homero的董事会。有很多关于组件的想法，但这是我的答案，基于许多工程经验和多年的建筑物。组件不需要仔细匹配。有了这一说，我会使用那些订购的人。例如，对于它们周围的PNP输出晶体管和电路;如果您订购10或来自Digikey或Mouser的100个晶体管，您将发现它们最有可能来自同一制造批次。这意味着它们在公差中彼此更靠近。我之前测量了几个批次的组件，同时它们在其公差范围内，来自相同批量（制造运行）的组件彼此相互较近。即使是我们在做什么时我们正在做的事情......

And even that won't drastically affect the microphone due to its low impedance output. The mic preamp input circuitry tolerances are more important for that. Short answer: Buy new decent quality components and you will be fine. Don't pull from your junk drawer.Good Luck!Jules

Thank you. I have not sorted out the body yet for the "Ambisonic Alice" I do have a3D printed saddle for the capsules. The body is next. It is my #1 project to get done now.

You can make it either 110 or 220VAC by selecting the transformer for the Power Supply. Just get one that is 110 or 220 for the primary and 24VAC center tapped for the secondary.Jules

通过PM接触我，我会看看我是否可以提供帮助

不客气！It is feedback like that yours that makes it all worth it. Best,Jules

That would be a great project. I used what I had when I built mine. I have some other 3" drivers that I bought I bought bulk that have been waiting to go into a line array... I need to finish that one!Please build your design and share.Jules

您希望将电压拆分为宿舍，因此如果现实世界是11.3伏，则要调整11.3除以4（或乘以1/4），为“A”和11.3次3/4次“B”。欢迎您参考。这些麦克风很棒，我只是有机会录制爵士乐合奏。将很快发布.Jules.Jules.

Yes it would...Jules

To get to 30hz you would need to use larger drivers that I used here. A friend of mine built a great line array using 8 inch drivers for the main array and one inch silk dome tweeters. And... he used Purple Heart for the cabinet. I don't have his design but the concept it the same as what I am doing.Jules

Excellent. I'm glad all is well. And yes, you can get quite good results with MS mic'ing. I cant wait till my kids orchestra starts up again. I think I might try some ambient location recording with it too.Jules

实际上，22nf上限会假设它是RF / EMI。这些应该很安静。您是否使用指示的组件？即PNP和FET？那些是关键的.jules

尝试：原理图板jules

是的，我会！我不得不尝试opamp的事情，我很高兴我做了。但是，我将使用MS Alice电路并将两对胶囊与90度彼此对准。嗯....时间突破烙铁......朱尔斯

其他两个二极管用于保护PNP晶体管。我选择不使用它们，但是设计董事会（Homero Leal）的人如果您想使用它们，请将它们放在那里。朱尔斯

It is so funny you asked that... That is just what I built this weekend. I have the mics built but need to do setup and testing, record a few things and finish up the instructable! Give me a week or two.Jules

The type of zener should not matter. You need one rated for 1/2W or better but they get larger as power rating goes up.Jules

我没有使用这两个齐纳，并且有很多关于他们对PNP晶体管保护的需要。我对此的看法是原始的Schoeps电路使用它们。如果你想成为子弹证明，请做。通过原始电路，他们没有使用我使用的47-49欧姆输入电阻，它们使用了铁氧体和无电阻。我也没有用多次热插拔我的麦克风滥用我的麦克风，但我有两次没有效果。还有许多电路变体（原始Alice等，请勿使用它们）我的原型悬挂或浮动的1GIG电阻器和FET的栅极引线。我没有使用电路板版本的问题。我使用水溶性助焊剂的焊料，然后用肥皂水和牙刷清洁良好。最后清洁异丙基a ...

No issues. Good luck and please share the KiCad drawing! Jules

听起来它是可调整的，麦克风工作，这很好！调整的目标在这里是分开电压，使FET能够处理它可以的最大理论信号。如果您可以在下腿上和6-12上升至6-12，您可以调整此问题。我可能会误解您的描述。请阅读这一点，看看它有助于：https：//www.dropbox.com/s/kqqx2fc2z3i46eo/fetbias.doc？dl = 0jules

你可以贴一些照片。这听起来像是锅中maybe open or something. the 12VDC and 0VDC indicates that there is no adjustment going on at all. One other possibility its the FET is not connected correctly. I did that a few times (rather embarrassingly...) but the pin outs do change between manufacturers also.Jules

不客气！是的，单个TSB-165代替TSB2555B。我有四个我内置于BM-700尸体中。它们是非常漂亮的小隔膜冷凝器。如果您构建了MS Alice，请订购另一个读者设计的3D印刷胶囊架。我买了三个，他们很快就会进入BM-800尸体。所有的Jules都是最好的

我刚订购了三个。将让每个人都知道他们是如何解决的。

不需要匹配组件。I used 1% resistors and 5% capacitors. Usually the actual values are much closer than their tolerance level would suggest. Jules

胶囊将产生巨大的改善。Micparts很棒。现有电子器件将有一点剩余噪音，但不可避免.jules

这次真是万分感谢！伟大的马鞍.jules.jules.

Awesome build! Thank you for the feedback too. I have a couple other projects brewing here using four capsules.Jules

我很乐意这样做。我不幸的是，没有空闲时间可以这样做。谢谢，朱尔斯

谢谢！Jules

优秀的！谢谢你分享这个.jules

Unfortunately USB supplies 5VDC so this won't work without additional electronics. It will work with a USB audio interface that supplies phantom power. Jules

谢谢！Jules

Yes you can! a shotgun mic uses a tube with slits or holes to cause interference patterns thus a more directional sound. See this patent for more details. Or, just look at any commercially available one. Jules

Those are great ideas and I think comercial line arrays vary the power to each zone. I am planning on building a bigger set of these and redoing the tweeter array. commercial ones are set up as an backwards "J" with the bottom curve facing down. Just am crunched for spare time these days!Jules
