Low Sound Hi, The sound on my keyboard is barely audible. I've tried it both with the adaptor & batteries. The volume is up to its full extent. Can you suggest anything? Thanks Patrick

Go to the menu and the settings, language & Keyboard Touch Input. Text Input under an other setting make sure that you have the sound feedback checked. If that is checked and its still not working try restarting your device. Sound feedback is checked; no sound for keyboard or menu/app selections.
When no sound is output even though the power is turned on, check the following points. Make sure that the master volume is not set too low. Set it to an appropriate level using the slider or knob. Make sure that nothing is connected to the headphone jack on the keyboard.

new or used,?
its not a computers it is a kids toy piano/organ keyboard
a crude musical instrument.
take it back to the store, try a 2nd one.
it's no good.

sound dead
sound weak
sound distorted
the knob has no effect at all on level of sound "volume"
or what?

"to work"means not much sorry....

did you read the manual first? have one? get one,.
we are in USA, I seem this thing sold in UK not here.

Hi
In terms of no electrical power it could be either a faulty power adaptor, broken socket. However the feedback with batteries could indicate a more serious fault. If the batteries are know to be good try a reset. Hold down the highest sounding key while turning the keyboard on. Release once you have lights or a display on screen. Has the noise stopped? If so then try electrical connection again, if still no power ensure you are using the correct power adaptor and see if it works if you wobble the connector - they break away causing an intermittent fault. Report back and maybe I can offer more advice depending on how you progress with the above.

On organ mode, in general, almost all brands of the modern keyboard, velocity setting is not enabled. Setting velocity is used to determine how much the level of the sound that follows how strongly you press the keys. It is really just to imitate the sound of vintage organs, which in the past, electronic organ technologi not use the velocity on the keys. So, how strong / slow we press the keys, the sound level will remain the same.
At the Piano mode,modern keyboard using setting velocity. This also to imitate an acoustic piano, which, if we press the keys slowly, the sound level will be slow as well, and vice versa.
So, in your case,at the same volume slider, try to play on the organ modes, note level. Moving to the piano mode and press the keys securely powered (full power). Then the sound level should be equal to the organ mode.
On modern keyboards, also included organ sound that added velocity setting. Usually found on the user bank.

Hi!
At this point, I would just take it to a tech rather than poke around in it. It sounds like the power section is the problem as you have guessed, but without the technical knowledge you'd be shooting in the dark. That particular amp is right on the line of being expensive enough that would be worth repairing, but you might do just as wel to check Ebay for another used one.
Good Luck!

Hello.
I have a similar problem, I guess.
Do you have a "rusty" or fluffy sond out, too?

1. Try the volume

2. Your adapter may not be the proper voltage/amperage. If the adapter has ratings listed, make sure they match the keyboards ratings.

3. Try it with the headphones. If they work and the speakers don't, you've narrowed down your problem. There may be some damage or wiring problem within where the board meets the speakers, and/or before processing.

4. Try it with batteries. If that works, you need a new adapter.

Hi,
Since your keyboard works fine with the PC. That means the problem is with the keyboard's Speaker. Either your speaker cable or speaker itself is not working... you have to identify that whether the problem is of speaker wire or speaker.... see that whether the service manual of your gadget is available or not.. if available then purchase the same. It will help you a lot for while repairing
Hope this has helped you....
Thanks...

It might be that the contacts for the headphone jack is very dirty. Try using a cotton swab with a wd-40 on it to clean the inside contacts on the jack.
