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.
If SECONDARY PORT is set to REDUNDANT, check whether the unit is connected via the Dante [PRIMARY] connector.

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.
