PIP power already has the resistor and capacitor internally. You don't need to add them, just plug it in to the Sony and you should be good. Jules <dampfus.hansus@...> wrote: --

Hi all, I'd like to build a first order ambisonic 9V electret microphone, that I can travel with. Balanced outputs is important since I will need cable lengths of 6m and longer. What are the

Hello fellow mic builders, I've soldered some cables to the EM272 capsules, with + to signal and GND to GND. My Sony PCM M10 provides 3V of PiP. Should I also solder in the circuit from the data

Hey! Sorry I saw your message now. Yes I would love to trade, which primo capsules you have? I'm mostly interested in large diagram condenser ones, but I'm open to possibilities. How many capsules do

EM272 and EM273 appear to be exactly the same element with a different wiring. The 2-wire version has higher sensitivity, because of the gain of the FET in common-source mode, when the lower

EM273 is a 3-terminal version of EM272.? ie it is EM272 modified as on page 12 of SimpleP48.pdf dtd 29sep24 for use in SimpleP48RCA. This, with EM273 has MUCH better overload performance and should

The Primo EM273 is similar to the EM272 but with higher SPL handling (135 dB vs 119 dB). Also, the simpleP48 doc has a few ideas about increasing the SPL headroom of some capsules. The LOM basicUcho

I asked Jonas about these PCBs a while back, they are proprietary information. He will supply them to you, so may be worth asking if he can do some custom circuits on the same board for

Hi all, I have a pair of Lom basic Ucho mics, but sadly they clip if I use them on my piano. So I wanna try myself with capsules that have higher SPL and wanna get the best sound possible out of it

It's true for sounds that are radiated in the pruimary directivity lobe. When capsules are spaced less than one quarter-wave, that is verified.

Thanks! So you're saying the parallel capsule (case of two capsules) does in fact increase SNR by 3dB (in ideal mathematical conditions)? -c

sqrt 2=>3dB, not 1.4. 1.414 =sqrt 2.

Yeah other members here (Joules and Jerry Lee, not sure who I'm quoting here) have said "The concept is that the audio signal from the capsules is correlated and the def noise is not.? The math part

Thanks so much for the reply Casey - this is most helpful. I'd figured there shouldn't be any harm in doing #3 (apart from increased parts cost and space for components), but wanted to be sure there

Others will correct me if wrong, but based on what I've read here about this: With Simplest P48 (capsule + resistor + capacitor) you can indeed parallel the capsules. You use a single

Hi all, First post on here - I've done a search through the group but couldn't find a definitive answer. I've been mucking around lately with aom5024 capsules to go along with the clippy mics that I

The MA1 circuit is a blatant rip-off of the Triton Fethead version 2, which is marginally less bad than the version 1.

Isn't the cascode an inverter?

The schematic is in error. XLR1 Pin 3 goes to XLR 2 Pin 2. XLR1 Pin 2 goes to XLR 2 Pin 3. This implies that we get a polarity shift. Very bad design indeed. Is this really the original schematic or a
