SP-303
fig.fig1
(200 mV/DIV, 1.00 ms/DIV)
Rotate the VOLUME handle “all the way to the right” -> ”all the way to the left”
-> “all the way to the right” and check that the amplitude of the waveform
changes from maximum -> minimum (without amplitude) -> maximum.
In the same way, check that the above waveform is output by connecting the
oscillator and oscilloscope to INPUT R and R channel side of the PHONE
terminal and if the amplitude changes with the function of the VOLUME handle.
Pressing the blinking [REC] botton proceeds to the next test.
7. MIC CHECK
“MiC” appears.
Check the function of the signal input to MIC IN at the time of output from
OUTPUT L and R .
7.1 MIC LEVEL CHECK
Set the oscillator to rectangular “200 Hz and 15m Vp-p” wave and input to MIC IN.
Rotate the VOLUME handle “all the way to the right.”
Rotate the MIC VOLUME handle “all the way to the right.”
Connect OUTPUT L to the oscilloscope and check that the following
rectangular wave is output.
fig.fig2
(200 mV/DIV, 1.00 ms/DIV)
Rotate the VOLUME handle “all the way to the right” -> ”all the way to the left”
-> “all the way to the right” and check that the amplitude of the waveform
changes from maximum -> minimum (without amplitude) -> maximum.
Rotate the MIC VOLUME handle “all the way to the right” -> ”all the way to the
left” -> “all the way to the right”, and check if the amplitude of the waveform
changes from maximum -> minimum (without amplitude) -> maximum.
In the same way, check if the above waveform is outputted by connecting the
oscilloscope to OUTPUT R, and if the amplitude changes with the function of
the VOLUME and MIC VOLUME handles.
8. CARD CHECK
“Crd” appears.
Check the loading and writing function of the SmartMedia.
When executing this test, always use the SmartMedia initialized in the
[Initializing SmartMedia.] procedure.
Insert initialized but not write protected SmartMedia.
“Wr” appears and the dot blinks, and writing test is executed automatically.
“rd” appears and the dot blinks, and loading test is executed automatically.
When stopping with “Err” display, press the [CANCEL] button and execute
the test again.
When the test is completed without any problems, “End” is displayed.
Turn off the power and end the test mode.
Remove the SmartMedia and execute the following test after turning the
power on as usual.
9. MUTE CHECK
Check that the MUTE function is functioning
Connect a headphone to the PHONE terminal.
Rotate the VOLUME handle “all the way to the right.”
Turn on the power while listening to the headphone sound.
At this time, check if no sounds are produced after hearing a “snap” from the
headphone.
10. NOISE CHECK
Check that noise from the wiring is not heard from the headphone.
Connect a headphone to the PHONE terminal.
Turn on the power.
While listening to the headphone sound, check if no [clicking] noise is heard
form the headphone when rotating the VOLUME handle to 9, 12 and 3 o’
clock to the right sequentially.
*
When a noise is heard, shape the wiring with [Shaping the wiring] and execute
the test again.
11. EFFECT CHECK
Check if the Effect function is functioning
Turn on the power.
After "303" and dot of a display disappears, keep pressing the NUMBER SW
[1] button.
At this time, if in a factory shipment condition, the sample sound of the drum
playbacks in loop.
Press the [MFX] button
Rotate CTL1, CTL2 and CTL3 “all to the left” and then “all to the right.”
Check if sample sounds have reverberation.
12. MIDI CHECK
Check the function of the MIDI note data at the time of input.
Connect the MIDI OUT of machine (PC-200 etc) which can output MIDI note
data and MIDI IN of SP-303.
Set the MIDI channel of the connected machine to “1 ch.”
*
When all test mode ends, SP-303 is set to “1ch.”
Turn on the power.
When sending the note number (C2-G2, D#3) from the connected machine,
check that the SP-303 pad (BANK A, 1-BANK A, 8, BANK B, 8) rings.
*
Receiving a note number of pad with no sample sound will produce no sound.
13. PROTECT CHECK
Check the SmartMedia protect function.
Attach a write protect seal to the SmartMedia used in [8. Card Check].
Insert the card when the power of the SP-303 is turned off.
Turn on the power.
Press the BANK [C] button
Press the [REC] button
At this time, check that “Prt” appears.
All tests are now completed.
