Troubleshooting
1. The power supply cannot be switched on.
- Plug the power cable all the way into the AC inlet (the power connector on the back
of the amp).
- Check that there is power at the AC outlet you are using (e.g., plug in another
device and turn it on).
2. The power supply can be switched on, but no sound is heard.
- Check to see if the volume on the amplifier is set to '0'.
- Check to see if the volume on the guitar is set to '0'.
- Make sure that the output of your guitar or effect processor is connected to the
INPUT jack.
- Remove the effects between the guitar and the amplifier and check to see if no
sound is produced.
- Make sure that the shielded cable between your guitar and amp is not broken. If
you have another cable, try using it.
3. Noise is heard.
- Check to see if the plug cover on the shielded cable is loose.
- Check to see if anything in the immediate vicinity is resonating or banging against
the amplifier to produce the noise.
- If you are using any compact effect devices between your guitar and amp, try
removing all of them, and check whether the noise occurs when only the guitar and
amp are used.
9. HEADPHONES jack
The 1/4" jack headphone output socket to enable headphones to be connected.
Stereo-type headphones can be connected. If headphones are used, sound will not
be output from the built-in speaker.
Warning
You must turn the amp volume to 0 before you connect or disconnect the headphone
plug. Note that the noise and distorted sound signals produced when inserting or
removing the plug with high volume levels will not only result in damage to the
headphones, it may also result in damage to the user's hearing.
You should also be careful not to raise the volume excessively when using
headphone. Playing through headphones at a high volume for an extended period
may damage your hearing.
10. POWER switch
The switch to turn the power supply on and off. Ensure that this switch is set at OFF
when the amplifier is not in use.
Warning
Before you turn on the power of the amp, make sure that volume control is set to 0. If
you turn on the power when the volume controls are already raised, a sudden loud
noise may be produced, possibly damaging your hearing. Please use caution.
- Make sure that the shielded cable between your guitar and amp is not broken. If
you have another cable, try using it.
- Make sure that the action (string height) of your guitar is adjusted correctly. If the
action is too low, the strings may buzz against the fingerboard, producing noise.
4. No sound when you connect a CD player
- Make sure that the volume of the CD player is not turned to 0.
- Make sure that the cable is connected correctly.
5. No sound is produced in the headphones
- Make sure that you are using stereo headphones and that they are correctly
connected. In particular if you are using an adaptor plug, make sure that the
adaptor plug is stereo.
