sonorizare biserica


Recommended Posts

se pricepe cineva la sistemele de sonorizare din biserici ?


n-am reusit sa fac poze dar sistemul cuprindea : o chestie patratoasa cu multe leduri si potentiometre in care se infigea si microfonul

 de asta se laga doua chestii mai mici,gen ups-uri casnice ,pe unul scria Interior ,pe altul Exterior,fiecare avea cate o iesire de boxe

in care erau legate in paralele toate boxele (boxe plate la interior,lungi si de table la exterior)


cineva a legat niste boxe clasice,luate de la o combina,legate pe Interior,acestea se aud bine,dar cele originale de pe pereti nu se mai aud deloc..

Dupa cum povestesti ca se comporta as zice ca sint nicte amplificatoare de linie cu iesire de 100V.

Boxele au trafuri adaptoare de impedanta inauntru si posibil si amplificatoarele dar conectate invers (ridicatoare de tensiune nu coboritoare ca la cele din boxe.).

Deconectati boxele 4-8 ohmi, si porniti amplificatorul. Daca boxele cu transformator functioneaza, nu s-a defectat nimic. Daca nu functioneaza, trebuie verificat amplificatorul(electronica, transformator iesire, etc).Boxele 4-8 ohmi pot fi cuplate la acest amplificator, numai prin intermediul unui transformator coborator.
