Troubleshooting
If you suspect a malfunction, please check the following points first. If this
does not resolve the problem, please contact your dealer or KORG Distributor.
Problem Possible remedy
The instrument
will not turn on
Check that the AC cable is not damaged, and it is correctly connected
to the piano and the outlet.
No sound 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:
• Pre-FX Comp: Intensity = 0
• Pre-FX Boost: Intensity = 0
• Amp Models: Drive = 0
Something
missing
If you are using the XLR outputs, make sure you have connected both
outputs. Mono output is not possible with the XLR jacks.
Weak sound 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.
Noisy audio 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.
