Fault
Playback sound is muffled and high
frequencies are inaudible.
When playing back tapes recorded on
other decks, meter deflections are
greater (smaller) than when recording.
Cause
¶
A tape recorded without Dolby NR is
played back with Dolby NR on.
¶
Heads are dirty.
¶
Heads are magnetized.
¶
Basic levels are different for different
cassette decks.
Cure
¶
Playback in OFF position.
¶
Clean heads and carry out
demagnetization with head
demagnetizer.
¶
This is not a fault.
