OLD MIC "МКЭ-3" TEST

Микрофон МКЭ-3 (МКЗ-3) 1986,
Ierunis (mikrafons) MKZ-3 1986,
Microphone MKZ-3 1986 = MIC
4-20mV/PA
50Hz-15kHz
Sensitivity=30dB
U=4,5V +/-30%  (3...6V)
18 minūšu video:


Papildināts 21.03.2017:

Mēģināju ierakstīt uz citām iekārtām, un secinājums ir nožēlojams, žēl patērētā laika
- pārāk trokšņaini mikrafoni (S/N) -30dB!!!

Piemēram, teicaman mikrafonam WM-61A ir S/N ap -62dB, 10db = 3, 20dB ir 10 reizes, 30dB ir 30 reizes mazāks trokņu līmenis.
