PB Sensitivity Adjustment (DECK1, DECK2)
Settings :
• Test tape :
TTA–200
• Test point :
TP1 (Rch), TP2 (Lch)
• Adjustment location : SFR301 (DECK1, Lch)
SFR302 (DECK1, Rch)
SFR303 (DECK2, Lch)
SFR304 (DECK2, Rch)
Method :
Play back the test tape and adjust SFRs so that
the output level of the test point becomes
245mV (DECK2), 260mV (DECK1).
5. PB Frequency Response Check (DECK1, DECK2)
Settings :
• Test tape :
TTA–300
• Test point :
TP1 (Rch), TP2 (Lch)
Method :
Play back the 315Hz and 10kHz signals of the
test tape and check that the output ratio of the
10kHz signal with respect to that of the 315Hz
signal is 0dB .
Next, check that the Lch and Rch difference
level of 10kHz signal is less than 2dB.

1. Tape Normal Speed Adjustment
Settings :
• Test tape :
TTA–100 (Tape center)
Play back the test tape and adjust SFR1 so that
the test point becomes 3000Hz
±
5Hz(FWD)
Then check REV speed is 3000Hz
±
45Hz.
After normal speed adjustment, play back
(High speed) the test tape. Then check tape
speed is 6000Hz
3. Head Azimuth Adjustment
Settings :
• Test tape :
TTA–300
• Test point :
TP1(Rch), TP2 (Lch)
• Adjustment location : Head azimuth
adjustment screw
Method :
Play back the 10kHz signal of the test tape and
adjust screw so that the output becomes
maximum.Next, perform on each FWD PLAY
and REV PLAY mode.
