Troubleshooting

If you experience problems, read this chapter first/ It contains tips for solving most problems.

Is the AC adaptor connected correctly?

Check the connections, and make sure that the AC adaptor plug is inserted firmly into the DC IN jack.

Are the batteries installed correctly?

Make sure that the batteries are installed correctly. Check that they are oriented correctly, and that they have 
not popped up out of their place.

Could the batteries be exhausted?

Install fresh batteries.

If the battery indication in the level meter screen shows

(little capacity remaining), replace the batteries 

as soon as possible.

Is the AC adaptor connected to the DC IN jack?

If the AC adaptor’s plug is connected to the DC IN jack, the M-10DX cannot operate on batteries even if 
batteries are installed. Unplug the AC adaptor if you want use batteries.

Could the input volume be too high?

The sound may be crackly or distorted if the input volume (level) is too high. If you’re inputting audio from 
an input jack, adjust the M-10DX’s input volume (level).

“Basic use” (p. 17)

Are you mixing multiple channels?

Even if the input volume (level) of a single channel is appropriate, the sound may be louder when you mix 
several channels, possibly causing crackling or distortion. Please re-adjust the input level of each channel.

Are the equalizer levels appropriate?

If you turn an EQ knob (HI/MID/LO) too far toward the right, the sound may be crackly or distorted. Use the 
EQ knobs (HI/MID/LO) of each channel to re-adjust the equalizer levels.

Are the insert effect, finalize, room acoustic control, and FX 
settings appropriate?

Depending on the settings of each effect, the level may increase, causing the sound to be crackly or distorted. 
Check these settings and re-adjust them if necessary.

Power does not turn on (when using the AC adaptor)

Power does not turn on (when using batteries)

Sound is crackly or distorted
