Spreadsheet updated. A lot of "unknowns" with Roon and Audiolense Convolver because I was unable to glean the information from the...

I'm late. Some measurements of Earthworks 1022 mic pre. If not, please tell me.

Actually, he's explaining the same I'm trying to explain. And his bargraphs are similar to my sensitivity graphs, except he's just...

They making multimeters now? ;)

For audio interfaces with Mic preamp, low level / high gain noise is a key performance parameter. I therefore always measure EIN when...

AFAIK there is no 'norm'*, but EIN is indeed typically given with A-weighting, as the value then is about 2.5 dB higher (better) than...

It's also good if Pro standards are moving towards less legends and more actual objective performance. Improve the quality at the very...

You’ve really been cranking them out lately Amirm. Thanks for all the time you take, grateful for your generosity.

Widely used doesn't mean it makes sense to define the input noise of the PREAMP. dB(A) is also widely used to measure environmental...

The noise of an 150Ohm resistor is 0,23uVrms (20-22kHz) and 0,18uVrms A weighted. So the noise of the resistor alone would be...

I I'm not sure there actually is a norm. Personally I do 20Hz-20kHz, but that's an arbitrary choice. Most vendors give 150 ohm dBu(A)...

Good design. Shielded power supply. Isolated sections and smart component layout.

Was asking myself the same question. In any setup, be it a large recording studio, small home studio or mobile recording, you'll be...

I have been working on this project for a long time, and finally finished it. The concept is simple: a 3-way speaker with full-range...
