Maintenance - Yamaha MT8X Operation Manual

MAINTENANCE

If the recorder is used for a long period of time, the heads, pinch roller and capstan will become dirty and the heads will
become magnetized. These can cause any of the following problems to occur.
• Recording, playback and erasure are not possible
• Sound level becomes low
• Fluctuating sound or signal dropout
• Excessive noise
• A drop in level at high frequencies
If these symptoms are observed, first try cleaning the recorder.
To make sure the head is always kept clean, it should be cleaned after every ten hours of use.
*Always clean the recorder before doing any important overdubbing and mixing.
Cleaning the Recorder
Apply a few drops of head cleaning fluid or pure alcohol to the cotton swabs included with the recorder, or to any
cotton swabs available on the market, and wipe the head, capstan, and pinch rollers.
Demagnetizing the Heads
When the recorder is used over a long period of time, metallic sections and head sections which come in contact
with the tape become magnetized, and this can cause deterioration of the characteristics. The head should be
demagnetized using a head eraser (a demagnetizing unit) after every 20 to 30 hours of use.
To do this, please refer to the instruction manual that comes with the head eraser.
Raising the Head
While holding down the PLAY button and REC SELECT switch 1, turn on the POWER switch and press the PLAY
button again. The head can be lifted up even when there is no tape in the recorder and the REMAIN indicator
flashes. The head should be in this position while being cleaned.
After the head has been cleaned, always press the STOP button and turn off the power supply to return the head to
its original position. If the recorder is used with the head in the raised position, the button operations may not match
the corresponding displays.
