Troubleshooting

Sound and keyboard

When I connect to an external device, noise is generated.

When connecting an external device (PC, Audio interface, Mixer, etc.), noise may be generated if it is wired in a loop. This phenomenon is called "ground loop noise" and not a failure of musical instruments. Noise may be improved by changing the connection method or by using a commercially available "USB Isolator" or "Ground Loop Isolator for Audio".

The sounds from headphones are distorted or too small, but it correctly sounds on speakers.

The multi-pole plug for smartphones is not available. Please use the headphones with three-pole stereo plug. If the sounds from headphones are small even if the volume is maximum, please confirm the impedance of your headphones. High impedance headphones may reduce the volume of sound.

It does not cut off the sound of speaker even when I connect the headphone.

Some models can sound with headphone and speaker at the same time. Check whether the speaker output is OFF position when connecting PHONE jack.

No sound is produced from the built-in speaker

Please check the following items: -Is there any headphones or an adapter plug in the PHONES jacks? -Is the power switched on? -Check whether the sound volume is the minimum position. - If there is the speaker ON/OFF function, check whether the speaker is ON position. If you can not solve this problem, contact us about repair.

I can hear sound from the speaker even when the volume is minimized. Is this a malfunction?

There are some models that leak a little sound when the volume is turned down to the minimum position, but this is not a malfunction.

The Left Side of my Keyboard is not working. How can I fix it?

Turn off the "Fingered Chord" setting. With Fingered chord, keyboards make sounds only when playing the chord properly. The area of chord keyboard is the left of the split point (refer to the user's manual).

I can only hear a sound from one side of my headphone.

-Ensure that the headphone jack has been inserted all the way into the PHONE jack of the instrument. -Do not use the headphone with Multi-pole plug connectors such as dedicated for iPhone or smartphone. - When connecting the headphone with 3.5mm stereo mini-plug to the instrument with 6.3mm stereo standard jack, please use the adaptor of 6.3 mm stereo plug from 3.5 mm stereo jack. -When the output of your conversion plug was monaural (MONO), please use the stereo conversion plug. Monaural: One black line at the end of the plug Stereo: Two black lines at the end of the plug
