    A small number of models of tuners and receivers were offered with the necessary decoder built in. In addition, a few cassette deck models appeared that allowed the deck's internal Dolby B decoder to be put in the line level pass-through path, permitting its use with Dolby FM broadcasts. The system was not successful and was on the decline by 1974.
