MT8XII—Owner’s Manual
Demagnetizing the Record–Play Head
As the tape passes over the record–play head, it imparts a tiny amount of magnetism to the head.
During normal use, this magnetism can build up to the point where audio performance is
affected. Therefore, you should demagnetize the record–play head at regular intervals using a
commercially available tape head demagnetizer. These are available at most audio and electron-
ics shops. A hand-held demagnetizer is preferable to the cassette-type demagnetizers.
It’s recommended that you demagnetize the record–play head before each new recording session
or after 25 hours of use, whichever comes first.
The demagnetizer should be turned on away from the MT8XII, passed slowly across the face of
the record–play head, and then drawn away slowly from the MT8XII and turned off.
Caution: Turn off the MT8XII before demagnetizing the record–play head.
Caution: Read the directions on the demagnetizer carefully. Misuse can damage the
record–play head. Also, do not place the demagnetizer close to magnetic storage media, such
as audio tapes and floppy disks. The demagnetizer emits a strong magnetic field and can erase
all information stored on such media.
