Troubleshooting - Yamaha DME64N Owner's Manual

Troubleshooting

Symptom
The DME64N/24N power won't
turn on.
No communication between the
DME64N/24N and the DME
Designer application software.
Cannot recall a scene.
The 96kHz/88.2kHz/48kHz/
44.1kHz indicators flash red.
No audio output.
When an external device is
being used as the word clock
master and the word clock
source is changed, noise
appears at the analog outputs.
The selected scene changes
unexpectedly.
User-defined parameter
settings change unexpectedly.
Possible Causes
The power cord is not plugged into an
appropriate AC outlet.
The POWER switch is turned OFF.
There is a fault in the DME64N/24N.
The DME64N/24N power is not turned on.
The DME Designer application is not running.
The connection cable is not connected properly.
The computer's USB port is not functioning
properly (in the case of USB connection).
The computer's Ethernet port is not functioning
properly (in the case of Ethernet connection).
Appropriate scene data has not been stored in
the DME64N/24N.
The DME64N/24N is not synchronized to the
selected word clock.
The [WORD CLOCK IN] connector cable is
disconnected. Select the [WORD CLOCK IN]
connector as the word clock source.
An I/O card is not properly installed.
No audio input is present.
There is no scene data.
The current scene is not properly wired to
produce audio output.
The mute function is engaged.
The output level is set too low.
The DME64N/24N is not synchronized to the
selected word clock.
You are attempting to run a scene that is not
compatible with 88.2/96 kHz operation at 88.2/
96 kHz.
This is normal, and can occur when an MY8-AT
I/O card is being used.
Scenes can be recalled via MIDI Program
Change message received from external
equipment if scene numbers are assigned to the
appropriate MIDI Program Change messages.
This is not a malfunction.
Scenes can be recalled via trigger signals
received from external controllers connected to
the GPI interface if scene recall is assigned as a
GPI function.
This can happen if multiple user-defined
parameters are assigned to the same
parameter.
The parameter(s) may have been edited from
another DME64N/24N in the same zone.
The parameter may be assigned to a MIDI
Control Change message via which it can be
edited from an external device.
The parameter may be assigned to GPI control
from an external controller connected to the GPI
interface.
Possible Solutions
Make sure that the power cord is plugged into an
appropriate AC outlet. Refer to "Preparation" on page 20.
Make sure that the POWER switch is turned ON. Refer to
"Preparation" on page 20.
Contact your Yamaha service center or representative.
Turn power to the DME64N/24N ON.
Launch the DME Designer application.
Make sure that the connection cable is properly
connected.
Refer to the DME Designer Installation Guide.
Refer to the DME Designer Installation Guide.
Set up and store an appropriate scene in the DME64N/
24N. Use the DME Designer for scene setup.
Select a different word clock source. Refer to the "WCLK
Page" section on page 51.
Connect the cable.
Make sure that an appropriate I/O card is inserted in an
I/O slot and that its screws are securely tightened. Refer
to "I/O Card Installation" on page 22 for details.
Make sure that an audio input signal is present.
Store appropriate scene data in the DME64N/24N scene
memory. Use the DME Designer application for scene
setup.
Redesign the scene to allow the desired audio output.
Disengage the mute function. Refer to "Mute Switching"
on page 42 for details.
Increase the output level. Refer to "Output Level Control"
on page 42 for details.
Select a different word clock source. Refer to the "WCLK
Page" section on page 51.
Set the word clock to 44.1/48 kHz.
Reduce the volume level of the power amplifier(s) to
prevent possible speaker damage, or make sure that the
DME64N/24N is off beforehand.
Use the DME Designer to check the MIDI Program
Change assignments.
Use the DME Designer application to check the GPI
input assignments.
If it is likely to cause confusion, it may be better not to
assign more than one user-defined parameter to the
same parameter. User-defined parameter assignments
can be changed via the DME Designer application.
Use the Panel Lock function (described on page 39) to
prevent unwanted operation from specific DME64N/24N
units or ICP1 control panels.
Use the DME Designer application to check the MIDI
Control Change assignments.
Use the DME Designer application to check the GPI
input assignments.
