[Test content]
For attenuation switches IN01 ~ IN16, add looped
signals from PHONES on the left-hand side (ON and
upper side of JK board) and check that the inputted
signals are being inputted into the CPU at correct gain
and correct attenuation level . Also check that no signals
are missing for other inputs.
[Test method]
Put all attenuation switches at H side (ON and lower
side of JK board) and maximize PHONES VR. Put in a
looped cable in order from IN01 to IN16.
[Check item]
Check LCD test results.
[Indication of OK]
If the above is displayed, connect a cable to IN02
(TOM1). (Go on to the next test.) Repeat in order until
IN16 is reached and confirmed.
[Indication of NG]
XXXXXX indicates too High, too Lo, XtalkIN 2, BAD
curve, etc.
[Indication of judgment result]
None
[Content of FAIL judgment]
No further step will take place.
[Completing the test]
Pressing the [ENTER/ YES] key proceeds to the next
test.
C- 84. OUTPUT L 1 kHz
[Initial indication]
[Test content]
Check that correct signals are being outputted from
OUTPUT (L/MONO).
[Test method]
Insert the standard (stereo) phone plug into both
OUTPUTs (L/MONO, R) and measure the output
waveform. Set the MAINOUT, AUX IN volume to
MAX. Check that no plug is inserted into AUX IN.
(Input voltage must be – 90 dBm or less.)
[Check item]
OUTPUT(L/MONO): When -5.1 +/- 2 dBm (load of 10
K
Ω
) OUTPUT (R) plug is pulled out
OUTPUT (L/MONO): -10.8 +/- 2 dBm (load of 10 K
Ω
)
