Re: capsule suggestion needed for loud environment recording
That capsule had a max SPL of 110dB. If you go straight to a condenser without built in FET you can pad it with a capacitor. I¡¯ve used the 2555B with a 220pF capacitor as a drum mic. It handles a

capsule suggestion needed for loud environment recording
Hello Folks,
I'm finally trying to get back to completing my SASS project using the? PUI 5024 capsules.
The SASS with the 5024's is intended for use in quiet, natural ambient recordings.

I think they're looking for a Switchcraft A5M, which is a whole plug - but the insert is what you find. Or copies of that design.

Where can I find a 5 pin connector for my dual true condenser Alice?
Like on of these, the one that mount inside the chassis with a screw. Can't find them anywhere!

You have a right to toot that horn a bit. https://audioimprov.com/AudioImprov/Mics/Entries/2015/4/23_Basic_FET_Microphone_Circuits.html was the post that got me started with this whole crazy obsession

Not to toot my own horn, but schematics of many mics I've tinkered with are on audioimprov.com. Not well organized, but there is a list of topics.

Re: True Condenser OPA High Impedance Stage

Ah! That all makes a lot of sense. I love that I learned a lot today. I realized that the TSB-2555 has a fixed static charge on the diaphragm and takes the signal from the backplate, similar to what

Thanks, Henry. This makes perfect sense. I figured that the second resistor was related to the signal coming from the backplate but you've explained why. I am interested in your comment about a

Re: True Condenser OPA High Impedance Stage

Here's why some have two 1G resistors, some have one. It comes down to capsule mounting and designer choices.
The capsule needs to have a polarizing voltage between diaphragm and backplate. Call it

Re: True Condenser OPA High Impedance Stage

Great question. The bias voltage is applied to the backplate. Then the diaphragm is connected to the virtual ground via the 1G resistor. That resistor ¡°develops¡± the signal via the voltage change

Beginner here.
I've been looking over the instructable for the True Condenser OPA and there are 2 things that I'm not completely understanding yet. I suspect they are related though. In other mics

Re: Dismantling LDC to use capsules as ORTF in a blimp
Headbaskets are intentionally moved to the front (not centered width wise) to minimise sound reflections from the top of the body.

I made rough drafts (xlr connectors and "headbaskets" are to scale), top and side view, to facilitate imaging.
