Troubleshooting
No sound? Wrong sound? When a problem like this occurs, please check the following points before assuming that the
product is faulty. Many problems can be solved by executing the Factory Set operation (page 15), after backing up your
data to an USB flash memory (page 36). If the problem persists, consult your Yamaha dealer.
No Sound.
Is this instrument properly connected to related external equipment (e.g., amplifier, speaker, headphone) via audio cables?
Since this instrument has no built-in speakers, you will need an external audio system or a set of stereo headphones to properly monitor it
(page 13*).
Is the power of this synthesizer and any external equipment connected to it turned on?
Have you made all the appropriate level settings—including the Master Volume on this instrument and the volume settings on any
connected external equipment?
If a Foot Controller is connected to the [FOOT CONTROLLER] jack, operate the Foot Controller and check the sound volume.
Check the Local Control parameter in the Utility display.
When this instrument is used by itself and this parameter is set to off, no sound is produced even if you play the keyboard.
Check the Direct Monitor Switch parameter in the Utility display.
When this instrument is used by itself and this parameter is set to off, no sound is produced even if you play the keyboard.
Are the MIDI volume or MIDI expression settings too low when using an external controller?
Are the effect and filter settings appropriate?
If you are using the filter, try changing the cutoff frequency. Some cutoff settings may filter out all of the sound.
Are the volume or expression settings too low?
No sound from the [AUX IN] jack.
Is the volume of the connected audio device set to a value other than “0”?
Cannot play audio data.
Is the volume for the audio data set to a value other than “0”?
