Troubleshooting

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

❏

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-16DX’s input volume (level).

➝

“Basic use” (p. 21)

❏

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.

❏

Is there a problem with the level indications in the level meter?

If the sound is crackly or distorted even though there is no problem with the level indications in the level
meter, the output volume is appropriate but the input volume is too high. Please adjust the M-16DX’s input
volume (level).

➝

“Basic use” (p. 21)

❏

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.

❏

Is the [USB] button lit?

❏

Could the channel 13/14 LEVEL knob be set to “-

∞

”?

Audio signals from the computer are input to channels 13/14. Use the channel LEVEL knob to adjust the
volume.
