Troubleshooting
Power doesn’t come on
❍ Is the guitar or keyboard connected correctly
to the INPUT R/MONO jack?
→ Check the connections again (p. 7–p.9).
* The power will not turn on without a plug connected to
the INPUT R/MONO jack.
❍ Have the batteries run down?
→ Replace them with new batteries (p. 6).
* The batteries included with the SL-20 are meant only to
confirm that the unit is functional at the factory.
* To reduce batteries consumption, be sure to disconnect
the plug connected to the INPUT R/MONO jack
whenever the unit is not in use.
❍ Is the specified AC adaptor (PSA series;
optional) connected correctly?
→ Check the connections again (p. 7–p.9).
Never use any AC adaptor other than the
adaptor specified.
No sound/volume is low
❍ Is the other equipment connected correctly?
→ Check the connections again (p. 7–p.9).
❍ Is the volume turned down on the connected
guitar, keyboard, effects processor, or other
device?
→ Check the settings on the connected equipment
(p. 7–p.9).
❍ Could the ATTACK knob or DUTY knob be
turned down?
→ Use the ATTACK knob or DUTY knob to adjust
the level.
❍ Could the connected expression pedal be in
the raised position?
→ When the expression pedal's function is set to
Direct Level, Effect Level, or Output Level the
effect sound is not output unless the pedal toe
is pressed down completely (p. 15).
❍ Have the batteries run down?
→ Replace them with new batteries (p. 6).
* The batteries included with the SL-20 are meant only to
confirm that the unit is functional at the factory.
The POWER indicator has gone dim
❍ Is the specified adaptor (PSA series; optional)
properly connected?
→ Check the connection once more (p. 7–p.9).
* Never use any AC adaptor other than one specified for use
with the SL-20.
❍ Have the batteries run down?
→ Replace them with new batteries (p. 6).
* When the indicator goes dim or no longer lights
while the effect is on, it means that the batteries
must be replaced.
* The batteries included with the SL-20 are meant only to
confirm that the unit is functional at the factory.
Sound is distorted
❍ Are the EFFECT LEVEL knob, DIRECT LEVEL
knob, and ATTACK knob positioned correctly?
→ Sounds may become distorted when the knobs are
at certain settings. Turn down the EFFECT LEVEL
knob, DIRECT LEVEL knob, and ATTACK knob to
an appropriate level. If in spite of these measures
the sound is still distorted, lower the output level of
the device connected to the INPUT jacks.
The volume level of the
instrument connected to the
INPUT jacks is too low
❍ Could you be using a connection cable that
contains a resistor?
→ Use a connection cable that does not contain a resistor.
Cannot save recorded slice sound
→ Recorded slice sounds cannot be saved in the
SL-20’s internal memory.
Unable to overdub
→ You cannot overdub during recording.
Sounds input in stereo are output
in mono
→ In order to apply effects suitable for the pattern,
some slice patterns mix the input, then output
this in mono.
Unable to switch output mode
→ The output mode setting is fixed at MONO
when the output is connected in mono.
