8. Tape speed Adjustment
Condition: • Test tape: TTA-100
• Test point: PHONES JACK
• Adjustment location: SFR of deck motor
Method: Play back the test tape and adjust so that the
5
output frequency is 3000Hz.
9. Azimuth Adjustment
Condition: • Test tape: TTA-320
• Test point: PHONES JACK
TC1
• Adjustment location:Azimuth adjustment
L108
TC2
Method: Play back the test tape and adjust so that the
output is maximum.
L107
10. AC Bias Adjustment
Condition: • Test tape: TTA-630
• Test point: TP1
• Adjustment location: L301
Method: Set up the recording mode. Adjust L301 so that
the TP1 becomes 70kHz.
