Labdien,
esmu iegādājies savu pirmo FPV:
https://www.hobbyking.com/hobbyking/sto ... duct=66474
Izrādās transmiterī nav iebūvēta mic. Saslēdzot transmiteri, kameru un bateriju, paliek pāri viens konektors, kas manuālī abzīmēts kā "audio in". Pieliku tur parastu mic un , protams, skaņas nav. Kādu mic man jāpievieno? Ir tādi ar iebūvētu pastiprinātāju? Uz konektora ir 0 Volti.

roljan, Vai tu mikrofonam padevi arī strāvu V+ ?
lai mikrofons strādātu, vajag: Volus GND un Audio signāla vadu.

Nepadevu gan. Varu ņemt strāvu arī no kameras un paralēli pievienot mic + konektoram?

viss atkarīgs no tā, ar kādu voltāžu darbojas mikrofons.
ja vtx darbojas ar 12V (3S) un mikrofons arī, tad jā, vari likt paralēli.

Darbojas uz 3S, bet mic droši ka nav 12V, jo izrauts no Logitech austiņām :)
Šāds derētu?

Gan jau ka derētu, tik nez kas videotransmiteram ir teikt par parametru: Output signal amplitude: 2.5 Vpp / - 25 db
Gan jau ka nekas nav teikts, jo nevienam šis parametrs nav baigi aktuāls.
Reku var iečekot šo piemēru Vismaz te teikts par Audio input (10K Ohm)` > 1Vpp typical

Vadi visiem ir 3 . GND, Mic OUT. V+ Štekeri jau vienalga cik tur salodēti , tāpat jāgriež nost.

...un vai vispār tas motors vēl strādā . Un ja kaut kur gadās nokrist , tad var dzirdēt ko cilvēki par tevi runā un domā
un cik rupji lamājas .

Jap, gribu dzirdēt motoru un apgriezienus. Visvairāk raustos, ka varētu pazust uztveramība pultij. Ar mic vismaz dzirdēšu notiekošo :)
