ADJUSTMENT

1. Tape Speed Adjustment Settings : • Test tape : TTA - 100 (TAPE CENTER)

• Test point : PHONES JACK (J1)

• Adjustment location : SFR 51

• Volume : NON-CLIP (MAX - 10dB DOWN)

Method : Play back the test tape and adjust SFR 51 so that the

frequency is 3000 Hz ± 10 Hz. Then confirm WOW is less than 0.50%.

2. Head Azimuth Adjustment Settings : • Test tape : TTA - 330 / 420 (TAPE CENTER)

• Test point : PHONES JACK (J1)

• Adjustment location : Head Azimuth Adjustment Screw

• Volume : NON-CLIP (MAX - 10dB DOWN) Method : Play back the test tape and adjust the screw so that

the output becomes maximum and same phase.
