❑ Is the SOLO/CUT switch set to CUT?
❑ Is the GAIN knob raised to an appropriate level?
❑ After connecting a device to an input jack, did you as-
sign it correctly to the mixer channel?

source into each mixer channel.
❑ Make sure that audio is being input.

Excessive noise or distortion
❑ Is the GAIN knob set appropriately? The sound will be
distorted if the TRIM knob is set too high, and there will
be excessive noise if it is set too low.
→ To obtain the best sound quality, the GAIN knobs for
the GUITAR, MIC, and INPUT 1–INPUT 8 jacks should
be adjusted as high as possible without allowing the
level meter to light red.
❑ Are you be using an effect?
→ Some of the effects intentionally add distortion or noise.
Check whether distortion or noise occurs even if you're
not using an effect.
❑ If the sound is distorting at the EQ, make the following
adjustment.
→ Adjust the gain value of the EQ.
Channel effect is not applied
❑ Have you assigned the channel effect to the correct
mixer channel?
→ Check the channel to which you assigned the effect.
Send effect is not applied
❑ Is the send level for ZERO FX SEND set to 0 or near 0?
→ Raise the send level.
❑ Is the return level for ZERO FX SEND set to 0 or near 0?
→ Raise the return level.
