12. Tape Speed Adjustment (DECK 2)
Settings : • Test tape : TTA–100
• Test point : TP5(Lch), TP6(Rch)
• Adjustment location : SFR1
Method : Play back the test tape and adjust SFR1 so that the
frequency counter reads 3000Hz
±
5Hz and
±
45Hz
(REV) with respect to forward speed.
13. Head Azimuth Adjustment (DECK 1, DECK 2)
Settings : • Test tape : TTA–330
• Test point : TP5(Lch), TP6(Rch)
• Adjustment location : Head azimuth
adjustment screw
Method : Play back (FWD) the 8kHz signal of the test tape and
adjust screw so that the output becomes maximum.
Next, perform on REV PLAY mode.
14. PB Frequency Response Check (DECK 1, DECK 2)
Settings : • Test tape : TTA–330
• Test point :TP5(Lch), TP6(Rch)
Method : Play back the 315Hz and 8kHz signals of the test tape
and check that the output ratio of the 8kHz signal with
respect to that of the 315Hz signal is within 5dB.
15. PB Sensitivity Check (DECK 1, DECK 2)
Settings : • Test tape : TTA–200
• Test point : TP5(Lch), TP6(Rch)
Method : Play back the test tape and check that the output level of
the test point is 230mV
±
3dB.
16. REC/PB Frequency Response Adjustment (DECK 2)
Settings : • Test tape : TTA–602
• Test point : TP5(Lch), TP6(Rch)
• Input signal : 1kHz / 8kHz (LINE IN)
• Adjustment location : SFR351 (Lch)
SFR352 (Rch)
Method : Apply a 1kHz signal and REC mode. Then adjust
OSC attenuator so that the output level at the TP5,
TP6 becomes -20VU (16mV). Record and play back the
1kHz and 8kHz signals and adjust SFRs so that the
output of the 8kHz signals becomes 0dB
±
0.5dB with
respect to that of the 1kHz signal.
17. REC/PB Sensitivity Check (DECK 2)
Settings : • Test tape : TTA–602
• Test point : TP5(Lch), TP6(Rch)
• Input signal : 1kHz (LINE IN)
Method : Apply a 1kHz signal and REC mode. Then adjust
OSC attenuator so that the output level at TP5, TP6
becomes 0VU (160mV). Record and play back the 1kHz
signals and check that the output is 0dB
±
3.5dB.

µ
-CON OSC Adjustment
Settings : • Test point : TP7 (O-KSCAN)
• Adjustment location : L101
Method : Insert AC plug while pressing TUNER function key.
Adjust L101 so that the frequency at the test point is
208.80Hz
±
0.21Hz.
