6. REC/PB Sensitivity Adjustment (DECK2)
Settings :
• Test tape :
TTA–602 (NORMAL)
• Test point :
TP1 (Rch), TP2 (Lch)
• Input signal :
1kHz (LINE IN)
• Adjustment location : SFR305 (Lch)
SFR306 (Rch)
Method :
Apply a 1kHz signal and REC mode. Then adjust
OSC attenuator so that the output level at the
TP1, TP2 becomes 0dB (17mV). Record and
play back the 1kHz signals and adjust SFRs so
that the output is 0dB
±
0.5dB.
7. REC/PB Frequency Response Adjustment (DECK2)
Settings :
• Test tape :
TTA–602 (NORMAL)
• Test point :
TP2 (Lch), TP1 (Rch)
• Input signal :
1kHz / 10kHz
(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
TP1, TP2 becomes 0dB (17mV). Record and
play back the 1kHz and 10kHz signals and adjust
SFRs so that the output level of the 10kHz
signals becomes 0dB
±
0.5dB with respect to
that of the 1kHz signal.
8. REC/PB Frequency Response Check (DECK2)
Settings :
• Test tape :
TTA–615 (CrO2)
• Test point :
TP2 (Lch), TP1 (Rch)
• Input signal :
1kHz
Method :
Apply a 1kHz signal and REC mode. Then adjust
OSC attenuator so that the output level at the
TP1, TP2 becomes 0dB (17mV). Record and
play back the 1kHz signal and check that the output is
0dB
±
2.0dB.
9. REC/PB Sensitivity Check (DECK2)
Settings :
• Test tape :
TTA–615 (CrO2)
• Test point :
TP2 (Lch), TP1 (Rch)
• Input signal :
1kHz (LINE OUT)
Method :
Apply a 1kHz signal and REC mode. Then adjust
OSC attenuator so that the output level at the
TP1, TP2 becomes 170mV. Record and
play back the 1kHz signal and check that the output is
0dB
±
2.0dB.
