1.ME-50B

2.Bass Amp /Stereo, Multitrack Recorder, Etc.

*Turn up the volume on amps and other equipment only after all connections are completed and the power for connected devices is turned on.

*This unit is equipped with a protection circuit. A brief interval (several seconds) after power up is required before the unit will operate normally.

Adjusting the Volume

Adjust the ME-50B’s volume with the MASTER LEVEL knob.

*Raising the MASTER LEVEL knob too much may result in sound distortion.

*When the effects are all off, input and output are at the same levels as when the MASTER LEVEL knob is at the center position.

*The setting of the MASTER LEVEL knob is stored in memory for each patch (p. 21).

If There Is No Sound/If the Volume is Low

●Are connections to other devices correctly made? Check the connections once more.

●Is the volume turned down?

Check the volume levels on any connected amp or mixer.

●Can you hear sound through the headphones when headphones are connected?

If you can hear sounds, it may be that there is a short in the cable used to connect the amp or other device, or perhaps a mistake in an external device’s settings. Check the connecting cables and external devices once more.

●Has the level been lowered with the expression pedal? Sounds are not output when the toe of the expression pedal is in the raised position while the pedal is set to function as a volume pedal (p. 18).

●Is the ME-50B in Tuner mode (p. 25)?

In Tuner mode, the bypass sound is output, and the expression pedal is used as a volume pedal.

When the expression pedal is used as a volume pedal, sound output falls as you pull the pedal back, raising the front of the pedal (p. 18).

●Is a cable containing a resistor being used to connect a CD or MD player to the AUX IN jack?

Using a cable containing a resistor may prevent sound from CD and MD players from being audible.

Turning Off the Power

1.Turn down the volume of the ME-50B and any connected device.

2.Turn off the power to Bass Amp / Stereo, Multitrack Recorder, etc.

3.Turn the ME-50B’s power off.
