    Sering kita temukan pengatur volume pd radio n Amplifier n dll.. dg Potensio sbg pengatur'y (penghambat)
    Kekurangan dr Potensio ini, klo sering diputar2 kan cepat aus dan Noise xg dihasilkan juga gede.
    Seiring dg usia potensio, output audio kan makin byk noise.

    Utk itu, bisa diganti dg jenis digital xg cukup simple.!!!

    Keterangan n component2 dr skema tsb:
    C1 = Capasitor keramik xg pipih 0.1uf
    U1 = DS1669 Digital Port IC
    S1/S2 = Swicth pengatur volume up or down
    Perangkat tambahan lain:
    Board PCB
    Socket IC DS1669

    *.Signal audio xg didukung IC DS1669 minimal 0.2Volt
    Utk lbh jelas karekteristis IC ini, liat attachment ;)..

    IC tsb tersedia di pasaran
    catu daya yg dibutuhkan, sesuai schematicnya dibutuhkan 5 Volt. Gunakan IC Regulator 7805 utk membuat 5 Volt Power Supply Regulated
    urutan kaki IC ... ya layaknya IC atuh! titik pada IC menandakan kaki no1
    utk potensio stereo, berarti Anda harus membuat rangkaian tsb 2bh

    Schematic dari Bos Orion Udah Jelas Qo :blah:
