Recomandare pentru 2 boxe 75W

Recommended Posts

Guest erwyn

Sall all am 2 boxe de 75W pe 8 ohm. As vrea o recomandare de amplificator pentru ele. Amplificatoru as vrea sa fie cat mai simplu si sa nu fie alimentat cu tref de peste 15V. E as zice un amplif de 40W miar ajunge dar nu am nici o schema simpla. As dori sa postati niste scheme de aplificatoare simpla si sa si duca boxele de 75W. :smt003

 

Da si era sa uit sam postati si cablaj ca sa nu ma chinui sal proiectez io! Multumesc!!! :partyman: :supz: :prayer:

 

Te rog sa nu mai deschizi posturi unu dupa altu, daca ai uitat sa adaugi ceva, ai la dispozitie butonul edit(modificare). EDIT sorteh.

OK am inteles si scuze

daca vrei sa folosesti un transformator de 12V atunci iti recomand TDA1562 care scoate 50w pe 4 ohmi fara distorsiuni, dar pe 8 ohmi puterea e mai mica.TDA7294 si LM3886 au nevoie de tensiune de alimentare mare. +/-30V DC.

nu ai cum sa scoti 40W pe 8 Ohm alimentat la 15V....din motive ca P=U*U/R deci la tine da 15*15/8=28W, dar daca mai punem tensiunea de saturatie a amplif...vreo 20 si cativa W ies...Oricum, LM3886 alimentat la +/- 16V e ok, am testat eu.
