Yamaha MT3X - Manual (Page 27)

MAINTENANCE
The MT3X 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 deck. 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 cleaning alchohol. Also clean the pinch roller at the same time as the
heads.
