    Default DIGI la...MAX

    Am probleme la volum! (nu e de la Tuborg, cârcotashilor!)...
    Coserva minunata Digi, când e la MAXim shi vrei sa o reduci spre tacere, reactzioneaza, auzibil, doar de pe la 30-25-20%, in jos...
    Numai la mine?...

    PS 1. Din cele 7 recivere uzitate de mine, nici unul nu s-a comportat ashishderea. E mai mult decat deranjant...
    2. De altfel: Traiasca Digi-Fanta-Mirosat!

    Tehnic ... ala este potentiometru de volum logaritmic. De la 0 - 5 cresterile si scaderile de volum de la o gradatie la alta sunt mai rapide, fata de 5 - 10, unde variatia de volum abia daca este sesizata. Dar aceste potentiometre se folosesc la sculele profesionale, mixere radio, tv, studiouri de inregistrare, asta pentru ca DJ-ul sa poate controla mai finutz interventiile voice-over, fara caderi si urcusuri brushte de fond muzical. La receivere, potentiometrul de volum (in cazul nostru digital - soft) ar trebui sa fie liniar. Ciudat

    In teorie toate potentiometrele de volum, fie ele digitale fie analogice, trebuie sa aiba scara logaritmica.
    Asta pentru ca asa lucreaza urechea umana: percepe scara logaritmica drept liniara.
    Daca folosesti un pot liniar pt volum constati ca stai o vesnicie cu degetul pe VOL+ pina ajungi la volumul dorit.

    @marius, sterila ta egzsplicatzie m-a bagat complect in ceatza... Unde mama ei de ureche o fi liniaritatea aia, daca nu merje?...
