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