ELECTRICAL ADJUSTMENT -6/7

15. Playback Sensitivity Check (DECK 1 and DECK 2)

Requirements

•

Measuring instrument: Millivoltmeter

Test tape: TTA-200 (400 kHz)

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

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

2) Insert the test tape (TTA-200) to DECK 1 and play back.

3) Check that the output level is ranged within 140 mV 3 dB.

4) Apply the above steps, 2) and 3) to DECK 2.

16. Record/Playback Frequency Response Adjustment (DECK 2)

Requirements

•

Measuring instrument: Millivoltmeter, Audio signal

oscillator (low frequency

oscillator), Attenuator

Test tape: TTA-602 (NORMAL)

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

Input point: AUX (1 kHz / 8 kHz)

Adjustment points: SFR451 (Lch), SFR452 (Rch)

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

2) Connect the output of the oscillator to the attenuator, and then the attenuator to AUX of the unit.

3) Insert the test tape (TTA-602) to DECK 2, and record 1 kHz signal from AUX.

4) Adjust the attenuator so that the output levels at TP8 and TP9 are ranged at 10 mV

5) Record 1 kHz and 8 kHz alternatively.

6) Play back the tape. Adjust SFR451 (Lch) / SFR452 (Rch) so that the playback output level of 8 kHz is ranged within

0 1 dB compared to the playback output level of 1 kHz as reference.

17. Record/Playback Sensitivity Check (DECK 2)

Requirements

•

Measuring instrument: Same as the above, 16

Test tape: TTA-602 (NORMAL)

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

Input point: AUX (1 kHz)

1) Insert the test tape (TTA-602) to DECK 2, and record 1 kHz signal from AUX.

2) Adjust the attenuator so that the output levels at TP8 and TP9 are 100 mV.

3) Play back 1kHz, and check that the output level is ranged within 0 dB 2.5 dB compared

to the recording output level.
