TROUBLE SHOOTING
The SY85 is a very versatile instrument with many features and functions that affect operation. In
many cases, what appears to be a fault with the SY85 can actually be traced to an improperly set param-
eter or, at the most fundamental level, to something as simple as a bad connection.
Here’s how to determine if the problem is internal (e.g. parameter settings) or external (e.g. connec-
tions, amplifier, etc.):
● Listen Via Headphones.
Plug a pair of headphones into the SY85 and play. If the headphone sound is OK, then the problem
is most likely in the amplifier or mixer you are using, or the audio connection cables.
● Check the Sound In the Voice, Performance, and Song Modes.
If the problem only occurs in one mode or one voice/performance/song, then the cause is most likely
a parameter setting related to that mode or voice/performance/song. If the problem occurs in all modes,
then the cause may be a utility parameter or other parameter that affects all modes.
The following are some common problems and probable causes:
● Amplifier, Mixer, Connection Problems
Symptom Possible Cause
No Sound
Distorted sound
• Is the amplifier/mixer power turned on?
• Is the amplifier/mixer volume set to an appropriate level?
• Are the SY85 outputs properly connected to the amplifier/mixer inputs?
• Are the connection cables shorted, open, or otherwise faulty?
• Is the SY85 connected to a high-sensitivity microphone or instrument input
on your amplifier or mixer? Try turning the SY85 OUTPUT controls down to
avoid overloading the amplifier/mixer inputs.
● Performance Mode Problems
Symptom Possible Cause
No Sound
Wrong pitch.
• Are voices properly assigned to the performance layers (page 14)?
• Are the voice volume parameters set high enough (page 15)?
• Is the total performance level set high enough (page 24)?
• Are the voice note and velocity parameters set to appropriate values (page
18 through 21)?
• If a foot volume pedal is connected or a controller is assigned to volume
control, is the controller set to produce a high enough volume level (page
31)?
• Are the note shift parameters for each voice set to appropriate values
(page 17)?.
