Vreau sa atasez acest mixer pe intrare la TDA 2030 dar vreau sa stiu mixerul la iesire cati mV scoate , daca sunt suficienti pentru intrarea in ampliful TDA 2030 , folosesc schema cu alimentare NESIMETRICA doar +22V si dupa cacule cu alimentarea de +22v am nevoie la intrare un semnal cu o tensiune de 0,33V.

Lista Componenta 3 Chanel Mixer de circuit Transistor
P1 = 5K P2 = 5K P3 = 5K R1 = 180K R2 = 2M2 R3 = 750R R4 = 1K R5 = 15K
R6 = 220R R7 = 1.5K R8 = 820R R9 = 150R R10 = 100K R11 = 180K R12 = 2,2 M
R13 = 750R R14 = 1K R15 = 180K R16 = 2M2 R17 = 750R R18 = 1K C1 = 1µF-63V
C2 = 100µF-25V C3 = 220µF-25V C4 = 100µF-25V C5 = 220µF-25V C6 = 1µF-63V
C7 = 100µF-25V C8 = 1µF-63V C9 = 100µF-25V Q1 = BC550C Q2 = BC547 Q3 = BC557
Q4 = BC550C Q5 = BC550C B1 = 9V J1, J2, J3 = 3mm Mono Jack SW1, 2,3,4 = Comutare SPST
