Rf filter audio recorder (Techniek Radio/TV)
Probeer het simpel te houden. Heeft de recorder ook last van het probleem als er op de ingang geen kabel zit?
Zonee, probeer dan eerst het volgende.
Van de cinch chassisdelen de aardhuls aarden met een keramisch condensatortje (kerco) van 10 of 22nF direct aan het frame, als deze aardhuls daarmee nog geen directe verbinding heeft. Een rechtstreekse aarde kan een aardlus veroorzaken, daarom de kerco.
De signaalader losmaken van het chassisdeel en daartussen een weerstandje , iets van 1K Ohm. Het knooppunt van de signaalader en het weerstandje via een kerco verbinden met het chassis. Deze kerco niet groter maken dan strikt nodig, i.v.m. hoge tonen verlies bij hoge waardes (470pF...2,2nF)
De onderdeeltjes zo kort mogelijk monteren.
Lukt het op deze manier niet, kun je de weerstandjes nog vervangen door RF chokes.
Blijft het probleem, dan is mogelijk een ingreep nodig in de voorversterkers.
