Troubleshooting
The power doesn’t come on.
❍ Is the guitar or keyboard connected correctly
to the INPUT A (MONO) jack?
→ Check the connections again (p. 4–p. 6).
* When running off batteries, the unit won’t switch
on unless there’s something plugged into the
INPUT jack. This helps conserve the batteries.
❍ Is the plug connected to the INPUT B jack?
→ When using battery power, connect the plug to
the INPUT A (MONO) jack.
❍ Have the batteries run down?
→ Replace with fresh batteries (p. 3).
❍ Is the specified AC adaptor (PSA-series sold
separately) connected correctly?
→ Check the connections again (p. 5–p. 6).
There is no sound.
❍ Is the other equipment connected correctly?
→ Check the connections again (p. 5–p. 6).
❍ Is the volume turned down on the connected
guitar/keyboard, effects processor, or other
device?
→ Check the settings on the connected equipment
(p. 4–p. 6).
❍ Is the effect level (EFFECT LEVEL knob) set to
minimum?
→ Operate the EFFECT LEVEL knob to adjust the
effect level (p. 8).
Sound is distorted.
❍ Are the EFFECT LEVEL knob and DIRECT
LEVEL knob positioned correctly?
→ Sounds may become distorted with the knob at
certain settings. Turn down the EFFECT LEVEL
knob and DIRECT LEVEL knob to 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 INPUT jack is too low.
❍ Could you be using a connection cable that
contains a resistor?
→ Use a connection cable that does not contain a
resistor.
