Error Messages
Troubleshooting
• No Sound
→ Is the power cord properly connected to the device?
→ Is the volume turned up on the instrument connected to the INPUT jack?
→ Are the INPUT LEVEL, GAIN, MASTER, OUTPUT control knobs set to “0”?
→ Check the Effect Loop’s BLEND setting (Compressor Mode: TREBLE control knob). Unless an external effector is connected
to the device, raising the BLEND control will result in lowering the original sound. If the BLEND control is set to “100”, the
original sound will not be produced.
• Sound output is low
→ Is the volume turned up on the instrument connected to the INPUT jack?
→ Are the INPUT LEVEL, GAIN, MASTER, OUTPUT control knobs turned up?
→ Check the Effect Loop’s BLEND setting (Compressor Mode: TREBLE control knob). Unless an external effector is connected
to the device, raising the BLEND control will result in lowering the original sound. If the BLEND control is set to “100”, the
original sound will not be produced.
→ Check the Compressor setting. A low Threshold setting or a high Ratio setting will result in a lowered the output signal level.
Also, a long release setting or low Compressor Gain setting will result in a lowered output signal level.
