6. Tape Speed Adjustment Settings : � Test tape : TTA�100 (Tape center) � Test point : PHONES JACK (J1) � Volume : NON-CLIP (MAX - 10dB) � Tape/Radio : TAPE � Tape select : NORM � MSP : CLASSIC � 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. Azimuth Adjustment settings : � Test tape : TTA�330/TTA-420 � Test point : PHONES JACK (J1) � Volume : MAX � Tape select : NORM � MSP : CLASSIC � 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 maxi mum.
