ADJUSTMENT <DECK>
1. Tape Speed Adjustment
Settings : • Test tape : TTA–100(TAPE CENTER)
• Test point : PHONES JACK (J1)
• Adjustment location : SFR1
Method : Play back the test tape and adjust SFR1 so that
the frequency is 3000Hz±10Hz.
2. Head Azimuth Adjustment
Settings : • Test tape : TTA–300
• Test point : PHONES JACK (J1)
• Adjustment location : Head azimuth
adjustment screw
Method : Play back the test tape and adjust the screw
so that the output becomes maximum and
same phase
