Double Dolby means that, on a tape deck with separate record
and playback heads, a separate cDolby processor is available
to decode Dolby on the playback head while the other
Dolby processor is being used to encode the recorded signal.
Some less expensive decks do not have this, and the
momitored signal therefore is not Dolby decoded. In the
playback mode the same Dolby processor is used as for
the recording. This of course is what always happens in
decks with a combinde record/play head.

The Dolby circuit can be B or C. If neither

is indicated, it generally is B.
