Схема: электретный микрофон XLR, фантомное питание, итоги и результаты

Twisted pair, shielded cable—this is the standard connection to the XLR connector. The ingenious idea of ​​an electret microphone, based on two properties of the jFET. 48-volt electret connection, phantom power. Standards for balanced connections and phantom power. Test recording of evening city sounds. Interference protection, experiments, and results on a spectrum analyzer. :: 02:00 - Demo, quasi-binaural recording 02:50 - XLR connection diagram 03:45 - Electret microphone capsule 06:02 - Connecting an electret to a 48-volt XLR 07:30 - Two connection options 08:39 - Ratings for this connection 09:23 - Balanced connection standards 10:05 - Schematic and cable for testing phantom power 11:06 - Question for experts 13:18 - Test recording with electret microphones 15:41 - Interference protection, condenser microphone 16:33 - Interference protection, electret microphones 18:36 - Question for experts 18:56 - Results 20:18 - Recording sounds of an evening city 21:20 - Balanced, symmetrical Schematics :: ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Everything for sale: list and prices https://drive.google.com/drive/folder... ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Questions/inquiries: Jürgen Maier [email protected] ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;    • jFET SENZOKU Preamp, Tube sound Saturator,...      • RIAA jFET preamp, vacuum triode sound with...   Harmotronix: https://sites.google.com/view/tubes-s... - Here's some reference and listening material. :: All my devices and circuit diagrams may be freely copied for personal use only.
