Recommended Posts

Guest Paulbosneagu

Salutare, as dori sa realizez 3 amplificatoare cu TDA 7294 si nu imi dau seama cum as putea din semnal stereo sa duc semnal in 3 amplificatoare, chiar si in 2 amplificatoare ar fi ideal. Ma poate ajuta cineva ? Un modul ceva ? Multumesc anticipat.

Da, dar ar as fi interesat(acum m-am gandit) si de 3 amplificatoare TDA 7294 in punte, fiecare amplificator sa aiba traful lui. Cum pot din semnal stereo sa duc semnal in 3 amplificatoare mono diferite ?

Trebuie mai întâi unite cele două canale stereo printr-un sumator rezistiv într-un singur canal mono, apoi distribuit semnalul la cele trei amplificatoare mono. Uite de unde te poți inspira: https://www.google.ro/search?q=sumator+audio+schematic&client=opera&hs=57c&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwjO5u6vjKrLAhWCB5oKHSiwAFIQ7AkIRQ&biw=1366&bih=658#imgrc=_

Si in cazul amplificatoarelor stereo cum se procedeaza ? Daca as avea 3 amplificatoare stereo si as vrea sa duc semnal stereo in toate, cum procedez ?
