12.9. Troubleshooting
The Yamaha Pro Audio website provides a FAQ (frequently asked questions and answers).
https://www.yamahaproaudio.com/
| Symptom | Cause | Possible Solution |
|---|---|---|
|
The power won’t turn on. The [POWER] indicator does not light. |
The power cable is connected improperly. |
Connect the power cable properly (see the AC IN connector section in “ Names and Functions ”). |
|
The unit is not receiving an input signal. |
The cables are not connected properly. |
Connect the cables properly. |
|
The internal head amplifier gain is not set to an appropriate level. |
Set the internal head amplifier gain to an appropriate level. |
|
|
START UP mode is set to REFRESH with MUTE, but the supported device has not started up. |
Start the supported device to send the settings to this product. |
|
|
The input level is too low. |
A condenser microphone is connected. |
Turn phantom power for the corresponding channel(s) ON. |
|
The internal head amplifier gain is not set to an appropriate level. |
Set the internal head amplifier gain to an appropriate level. |
|
|
No sound is heard. |
The cables are not connected properly. |
Connect the cables properly. |
|
START UP mode is set to REFRESH with MUTE, but the supported device has not started up. |
Start the supported device to send the settings to this product. |
|
|
The Dante settings for this product are not synchronized with those for the supported device. |
If you are using a supported digital mixer, set CONSOLE ID to #1 to synchronize the settings. If you are using other supported devices, use Dante Controller to synchronize the settings. |
|
|
The head amp cannot be controlled. |
This product has not been mounted on the RACK of the supported device. |
Mount this product on the RACK of the supported device. |
|
Adjusting the internal head amp gain does not change the audio level. |
GC (Gain Compensation) is turned on. |
If you are not using GC (Gain Compensation), turn it off. |
|
Dante Controller does not recognize this product. |
An incorrect value has been assigned to the IP address for Dante. |
Initialize this product. |
|
R Remote does not recognize this product. |
The UNIT ID setting conflicts with another R series unit. |
Specify a unique UNIT ID for each device. |
|
The IP address setting is incorrect. Alternatively, the network is connected incorrectly. |
Review the network settings. Make sure that they are set to the same subnet.
|
|
|
The [POWER] indicator is lit, but nothing appears in the display. |
A malfunction may have occurred. |
Contact your Yamaha dealer. |
|
Keys, switches, or encoder operations do not work. |
Panel Lock is enabled. |
Defeat Panel Lock. |
