Velocity PAD Check
Display: OK/NG
Devices related to the test: Panel:IC1
1. Strike each of the sixteen velocity pads to check the sensitivity.
2. The small rectangle detects a soft strike, and the large rectangle detects a
strong strike.
3. If both were detected, the rectangle will turn black.
Drive Check
FDD Check
Devices related to the test: Main:IC49,63,64, X5
* This test requires a formatted 2DD floppy disk.
Set the write protect tab of the blank 2DD floppy disk in the “ON” position,
insert it into the FDD, and press the [FD (2DD)](F5) button. The 2DD floppy
disk will be detected, and a Write Protect test will be performed.
CD-R/RW Drive Check
* This test requires a blank CD-R disc or a CD-RW disc.
1. Insert the blank CD-R disc or the CD-RW disc into the CD-RW drive, and
press the [BURN T-CD](F2) button. A test CD-R (or CD-RW) will be
created.
2. Then press [CD READ](F4) to perform a Read test on the test CD-R (or
CD-RW) that was created by [BURN T-CD].
3. If the CD could be read correctly, the “OK” result will appear.
FootSw Check
Display: OK/--
Devices related to the test: Main:IC38
* This test requires a foot switch such as the FS-5U or DP-2.
When the “ON” and “OFF” positions of the foot switch have been detected,
the “OK” result will appear.
Sound Check
Devices related to the test: Main:IC30,32,50,51,52,53,54,55,56,Q9,10,13,14
* This test requires an audio output device such as a CD player, and monitoring
equipment such as speakers or headphones.
1. Routing A: The sound that is input from ANALOG INPUT will be output
from MASTER, PHONES, and DIGITAL OUT without being affected by
anything other than SENS.
2. To switch between MIC/LINE and PHONO, insert or remove the plug
from the MIC/LINE jacks.
3. Input an audio signal into ANALOG INPUT, and use your headphones
or speakers to monitor the output from each OUTPUT.
Mute Check
Devices related to the test: Main:IC6, Q3, Q4, Q6, Q7, Q8, Q11, Q12, Q15, Q16,
D7
1. Each time you press the [MUTE SW] button, the Mute status will
alternate “ON” ---> “OFF” --> “ON” --> “OFF”.
2. Verify that sound ceases to be output from OUTPUT when “MUTE ON.”
It takes several seconds from when you switch “MUTE ON” --> “OFF”
until audio will be output.
USB Connect Check
Devices related to the test: Main:IC61, IC66
* This test requires a computer with a USB connector and a USB cable.
1. Use the USB cable to connect the MV-8000 to your computer, and press
the [Connect] (F4) button.
2. After the computer has detected the MV-8000 and connection, break the
connection from your computer.
3. When you then press either the [GOTO TOP], [PREV], or [NEXT] button
to exit this test, the MV-8000 will break the connection.
MV8-OP Check
* This test requires the MV8-OP1, an audio output device such as a CD player,
monitoring equipment such as speakers or headphones, an R-BUS device such as
the VS-2400CD, and various audio cables.
Routing G: The input from Digital In, R-BUS In, or Analog In will be output to
all channels of MULTI OUTPUT 1 - 6 and R-BUS Out.
Mute Check
Devices related to the test: MV8-OP1:IC1 - IC18, IC12 - IC18, IC21 - IC25, IC32 -
IC34
Press the [MUTE SW] (F4) button, and verify that the sound from MULTI
OUTPUT 1 - 6 is muted.
Input Check
Devices related to the test: MV8-OP1:IC11, IC19 - IC29
1. Connect cables to the OPT/COAX/R-BUS digital input and to the analog
input, and input audio data.
2. In the screen, successively select [COAX], [OPT], [R-BUS], and [Analog],
and verify that the same sound as the input is being output from MULTI
OUTPUT 1 - 6 or R-BUS Out.
3. When you select R-BUS, the Slave Mode will also be checked, so set the
word clock of your R-BUS device to “INT.”
PLL Lock Check
Devices related to the test: MV8-OP1:IC21, IC25
1. Connect an R-BUS cable to your R-BUS device, and start up the R-BUS
device.
2. Set the word clock of the R-BUS device to “INT,” and verify that the MV-
8000’s display changes from “Unlock” --> “Lock.”
Error Status Check
Devices related to the test: MV8-OP1:IC11, IC26, IC28, X1
1. Use a coaxial cable to connect a device that provides a digital output, and
then unplug that cable.
2. Verify that the MV-8000’s display changes from “Unlock” --> “Lock.”
R-BUS U-ART Check
Devices related to the test: MV8-OP1:IC18, IC21
Use a copper wire etc. to short TX (pin 14) and RX (pin 25) of the R-BUS, and
check the conductivity.
MV8-OP2 Detect
Display: OK/NG
Devices related to the test: Main:IC1, Panel:IC1, MV8-VGA
If the MV8-VGA is connected, the display will indicate “OK.”
PS/2 Mouse Detect
Display: OK/NG
Devices related to the test: Panel:IC1, MV8-VGA
The MV-8000 will detect whether a PS/2 mouse is connected. If a mouse is
detected, the display will indicate “OK.”
