Maintenance - Yamaha MT100II Operation Manual

MAINTENANCE

The MT100II recording & playback head has been precision-constructed to extremely fine tolerances in order to make high-quality 4-
track recording possible. Optimum performance can only be achieved if the head surface is kept immaculately clean. Cleaning
should be carried out at regular intervals — at least after every 10 hours of use.
Dirty heads can cause any of, or a combination of, the following problems:
•
Recording, playback and erasure are not possible.
•
Reduced playback sound level.
•
Fluctuating and or/distorted sound.
•
Excessive noise.
•
A drop in level at the high frequencies.
If any of the above problems occur, clean the heads carefull before assuming the fault is with the recorder. Use a commercially
available head-cleaning kit (read the instructions provided with the kit), or wipe carefully with a cloth or cotton swab that has been
dampened with isopropyl alchohol. Also clean the pinch roller at the same time as the heads.
