Maintenance "Ie - Yamaha MT120S Operation Manual

MAINTENANCE
Maintenance on your MT120S basically involves keeping the tape heads in the best possible condition. This involves two considerations
— keeping them clean, and keeping them demagnetized. |
As the magnetic tape passes over the tape heads, a very small amount of magnetism stays on the heads (rather like passing a magnet
over a needle). Over time, this builds up to a point where the heads become magnetized, and as the tape passes over the heads, the
tape itself (with your precious recordings) will start to be wiped. :
То avoid this, we recommend that you use a commercially available head demagnetizer on the tape heads, after every 10 hours of playing/
recording time. This may seem extreme, but we assure you, the results are worth it.
The 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 keptimmaculately 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. ` |
ө 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 careful 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 alcohol. Also clean the pinch roller at the same time as the heads.
