6. Tape Speed Adjustment
Settings: • MSP : Classic
•Tape/radio: Tape
• Tape select : NORM
•Volume: Non–clip (Max–10dB)
• 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 becomes 3000Hz±10Hz.
Then confirm WOW is less than 0.50%.
7. Azimuth adjustment
Setting: • Test point : Phones Jack (J1)
• MSP : Classic
•Tape/radio: Tape
•Tapeselect: NORM
• Volume : MAX
• Test tape : TTA–330/TTA–420
Method : Play back the 8KHz sigual of the test tape and
adjust screw so that the output becomes maximum.
