Buna seara, am cumparat doua module de 4 canale, doresc sa leg pc la el, am legat intrarile cu cablu ecranat pe direct, volumul il reglez din calculator, indiferent de volum la anumite frecvente medii baraie, nu doresc sa folosesc potetiometre, daca pun pe fiecare plus de pe intrare o rezistenta de 10k sau 20k se rezolva oare ? Volumul la pc este la 30 la suta si este foarte tare, se poate reduce din semnal linistit.TDA 8571J4x40wU intrare 500mVU intrare maxim 1Vvvimpedanta intrare 30kohmiMultumesc

Doresc sa lipesc pe plusul fiecarei intrari o rezistenta (10k, 20k, 50k) sa-mi mai scada din semnal. Volumul din pc este la 25 %. Multumesc.

Pana la urma nu am mai suportat si am legat potentiometre de 50k. Am redus volumul din ele la 75 % si ghici ce ? Baraie oricum la sunete de voce mai joase. Probabil atata poate integratul. Multumesc frumos pentru solutii !
