Troubleshooting
If the PX4D does not operate as you expect,
please check the following points first. If this does
not resolve the problem, contact your dealer.
1. Power does not turn on.
• Are batteries installed? Alternatively, is the
correct AC adapter connected to an AC out-
let?
2. No sound
• Are your guitar or bass, amp and/or head-
phones connected to the correct jacks?
• Is your amp turned on and set correctly?
• Are any cables broken?
• Is the master level of the PX4D set to “0” or
to a low level?
• The VOLUME control knob may have been
turned down.
• Is the PX4D muted?
Be aware that if all effects are off, the chain
display will disappear, and it will not be pos-
sible to distinguish Bypass or Mute from the
LCD display.
• Is the volume of your guitar turned down?
3. The volume from the device connected to
the AUX jack is too loud or too soft, or can-
not be heard.
• Adjust the output level of the connected de-
vice.
Make connections to the headphone jack of
the device, instead of to its line output.
• Are you in Phrase Trainer mode?
Exit Phrase Trainer mode.
• Are you using a connection cable with a built-
in resistor?
4. Effects do not apply
• Is the PX4D bypassed? (the effect chain will
be blinking)
• Are the effects used in the program turned
on?
5. Tuner does not work.
• Is the PX4D bypassed or muted?
