PiP capsule hum
Hey all -- I have a project I'm working on that involves a raspberry pi, a cheap USB audio interface <https://www.amazon.com/dp/B01N905VOY>, and a small electret capsule (JLI-61A

I need a pukka XP machine to run the software I wrote myself in da last Millenium.

Re: PCB for ambisonic mic with 9V power supply
Yes - sorry about the typo!? The ones I used are definitely the JLI-140A-T.

Re: PCB for ambisonic mic with 9V power supply
Do you mean JLI-140A-T capsules? I have a few of those. They're nice.
Thanks for sharing your circuit.

Re: PCB for ambisonic mic with 9V power supply
See the attached ZIP (KiCAD 8 project with schematic and board layout, Gerbers, and a PDF of the schematic).? It might be suitable for you to use, either as-is or as a starting point for changes.

Hi
Everything is fine with + capsule on + jack and ground capsule on ground jack.
The assembly of the technical sheet is already inside the recorder

Re: PCB for ambisonic mic with 9V power supply
No need to duplicate requests.
SimpleP48 is adequate for balanced lines of less than 20 meters. Does not require PCB's.

Re: Circuit for PiP EM272
The Sony PCM10, as well as all other products that provide PIP, include the protection capacitor and resistor.
Addding them would not have any benefit.

Re: Circuit for PiP EM272
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.

PCB for ambisonic mic with 9V power supply
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

Circuit for PiP EM272
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

Re: TSB2590 alternative?
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

Re: Lom usi circuit vs simple P48
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

Re: Lom usi circuit vs simple P48
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

Re: Lom usi circuit vs simple P48
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.

Re: Lom usi circuit vs simple P48
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
