If the JUNO-G does not function in the way you expect, first check 
the following points. If this does not resolve the problem, consult 
your dealer or a nearby Roland Service Station.

 

The power does not turn on.

Make sure that the JUNO-G’s AC adaptor is correctly connected 

to an AC outlet and to the rear panel power connector, and that 
the adaptor itself and AC power cable are connected correctly 
(p. 14).

volume turned all the way down?

• Have connections been made correctly?

• Can you hear sound through headphones?

If there is sound in the headphones, it is possible that the 
connection cables are broken, or that your amp/mixer has 
malfunctioned. Check your cables and amp/mixer system once 
again.

• If you do not hear sound when you play the keyboard, check 

whether the Local Switch is turned OFF.

Check the various output assign settings (p. 48, p. 57, p. 65, p. 
126, p. 127).

• Is the Wave Expansion Board properly installed?

When selecting the settings that stipulate the use of EXP waves, 
Patches, or Rhythm Sets, check that the Wave Expansion Board 
is installed properly in the slot (p. 174). 

• Has the volume been lowered by pedal operations or by MIDI 

messages (volume messages or expression messages) received 
from an external MIDI device?

The sound is distorted.

Check the following points.

If the sound for a specific patch or part is distorted, lower the 
volume level on that part.

• If all sounds are distorted, use the VOLUME knob to lower the 

volume level.

• Could the Output Gain be excessively high?

In “System,” check the “Sound” parameter.

Check the following points.

• Is the tuning of the JUNO-G incorrect?

The sound is interrupted.

Sounds will be interrupted if more than 128 voices are used 

simultaneously.
