Make the following preparations for DECK adjustment.
Preparations

• Measuring instruments: Audio signal oscillator/Attenuator/Wow-Flutter meter (frequency counter)/Oscilloscope/Millivoltmeter/Dummy

resistance (6

Ω

)

• Test Tape: TTA-100 / TTA-330/ TTA-200 / TTA-602 (or equivalent test tape for play/record)

1. Tape Speed Adjustment and Check

Requirements

Measuring instruments: Wow-flutter meter (frequency counter)

Test tape: TTA-100 (3 kHz)

Test point: TP8 (Rch), TP9 (Lch)

Adjustment point: MOTOR SFR

(1) Connect the TP8 and TP9 of the unit to the wow-flutter meter.

(2) Insert the test tape (TTA-100) to DECK. Playback the middle part of the tape in the FWD

direction, and adjust MOTOR SFR so that the level, 3,000 Hz

5 Hz can be obtained.

(3) Playback RVS, and check that the speed is less than

45 Hz to the speed of FWD.

2. Wow-Flutter Check

Measuring instruments: Wow-flutter meter (frequency counter)

Test tape: TTA-100 (3 kHz)

Test point: TP8 (Rch), TP9 (Lch)

(1) Connect the TP8 and TP9 of the unit to the wow-flutter meter.

(2) Switch the wow-flutter setting from INDICATOR to JIS, and from a mode to W RMS (WTD).

(3) Playback the middle part of the test tape (TTA-100), and check that the level is 0.25 % or below.

3. Head Azimuth Adjustment

Requirements

Measuring instrument: Oscilloscope

Test tape: TTA-330

Test point: TP8 (Rch), TP9 (Lch)

Adjustment point: Head azimuth adjustment screw

(1) Connect the CH1 of the oscilloscope probe to TP9 (Lch) and the CH2 to TP8 (Rch).

(2) Set the V mode of the oscilloscope to ADD.

(3) Insert the test tape (TTA-330) to DECK 1. Playback the middle part of the tape in the

FWD direction, and adjust the head azimuth adjustment screw so that the waveform

reaches maximum when 8 kHz is played.

(4) Apply the above steps to the side of RVS.

(5) After adjustment, lock the screw by bonding (1620B).

4. Playback Frequency Check

Requirements

Measuring instrument: Millivoltmeter

Test tape: TTA-330 (315 Hz / 8 kHz)

Test point: TP8 (Rch), TP9 (Lch)

(1) Connect the CH1 of millivoltmeter to TP9 (Lch) and the CH2 to TP8 (Rch).

(2) Insert the test tape (TTA-330) to DECK, and playback 315 Hz and 8 kHz.

(3) Check that the 8 kHz level is ranged within 0

5 dB compared to the output reference

level of 315 Hz.
