Troubleshooting

1. The power supply cannot be switched ON.
• Check that the power cable has been connected correctly.
• Try plugging it into a different power supply socket and see if the
same problem occurs.
2. The power supply can be turned ON, but no sound is
produced.
• Check that the guitar and microphone have been connected cor-
rectly.
• Remove the effects between the guitar and the amplifier and check
to see if no sound is produced.
• Replace the shielded cable and check to see if no sound is pro-
duced.
• Check to see if the volume on the guitar is set to "0".
• Check to see if the microphone switch has been turned ON.
• Check to see if there are batteries in the guitar. If there are, check
that they are OK.
• Use a different guitar and see if no sound is produced.
• Check to see if the volume on the amp is set to "0".
3. Noise occurs
• Check to see if anything in the immediate vicinity is resonating or
banging against the amplifier to produce the noise.
• Check to see if the plug cover on the shielded cable is loose.
• Check that the string action (distance between strings and frets) is
correctly adjusted (not too low).
• Check to see if the guitar batteries are depleted.
• Is the microphone used as unbalanced? If so, noise occurs easily.
• Use another guitar, microphone, effects and cable to see if the same
noise is produced.
