inlocuire potentiometre corector de ton


Recommended Posts

As avea o intrebare si de data asta: La corectoarele de ton TCA5500 si TDA1524 sau schemele compuse din A723si A724 deci care au controlul volumului si al tonului comandat in tensiune c.c.se pot inlocui acele potentiometre sau creata o mica interfata de la acele fire pt a pune doua butoane cu "+"si"-" ?Eventual mai apoi sa pot controla printr-o telecomanda?Daca da,cum?Astept sugestii.

potentiometrele le poti inlocui cu succes cu un circuit integrat seria MMC40192/3 (numarator reversibil bla bla) si un CD 4066 (nu am stat sa caut echivalenta dar probabil este "foarte" echivalent cu MMC4066) acesta din urma fiind un switch (intrerupator digital) . pentru a nu avea batai de cap cu comanda numaratorului up/down (+/-) este bine sa folosesti un generator de semnal (cu frecventa reglabila - ca sa nu ai surprize)daca te intereseaza si te pasioneaza cu adevarat , eu chiar lucram la un proiect asemanator doar ca m-am lovit de problema telecomenzi - am idei practice de realizare doar ca .. am prea multe idei :))
