6. Tape Speed Adjustment
Settings : • Test tape : TTA–100 (Tape center)

• Test point : PHONES JACK (J1)

• Volume : NON-CLIP (MAX-10dB)

• Function : TAPE

• Adjustment location : SFR51

Method : Play back the test tape and adjust SFR51 so that

the frequency becomes 3000Hz ± 10Hz(FWD).
Then confirm WOW is less than 0.50%.

7. Head Azimuth Adjustment
Settings : • Test tape : TTA–330/TTA–420

• Test point : PHONES JACK (J1)

• Volume : M AX

• Function : TAPE

• S-BASS : OFF

• Adjustment location : Head azimuth
adjustment screw

Method : Play back the 8kHz signal of the test tape and

adjust the screw so that the output becomes
maximum.
