does not resolve the problem, please contact your dealer or KORG Distributor.
Problem
The instrument
will not turn on
No sound
Something
missing
Weak sound
Noisy audio
Possible remedy
Check that the AC cable is not damaged, and it is correctly connected
to the piano and the outlet.
Make sure that the volume is not set on 0. If it is, bring it up to an
adequate level.
Make sure the volume/expression pedal is not set to minimum.
In the models with speakers: Check if the SPEAKER switch is turned
on; check if there is a jack inserted in the PHONES connector.
Make sure that the Local Off function is not turned on. If it is, turn it
off.
If you are listening in headphones, make sure the jack is correctly
plugged into the HEADPHONES connector.
Make sure there isn't one of the following control settings:
• PreFX Comp: Intensity = 0
• PreFX Boost: Intensity = 0
• Amp Models: Drive = 0
If you are using the XLR outputs, make sure you have connected both
outputs. Mono output is not possible with the XLR jacks.
If the sound is weak when using the Amp section, the valve may be ex
hausted. Please refer to the nearest KORG Authorized Service Center
for replacement.
Cables may be too long, or get interference from other devices on the
stage. Use the XLR connectors instead.
If the AMPLIFIER is turned on, you might be listening to the natural
noise of the amp's valve circuitry.
