6. Tape Speed Adjustment Settings : · MSP : Classic · Tape/radio : Tape · Tape select : NORM · Volume : Non­clip (Max­10dB) · Test tape : TTA­100 (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 · Tape select : NORM · Volume : MAX · Test tape : TTA­330/TTA­420 Method : Play back the 8KHz sigual of the test tape and adjust screw so that the output becomes maximum.
