Check that the power of that device is turned on.  No sound is output.  Are external instruments (including microphones) and speakers connected correctly?  Are your cables shorted?  Are the [GAIN] knobs for each channel, [LEVEL] knobs, [STEREO LEVEL] knob adjusted to appropriate levels?  Are the[LINE  The sound is low, distorted, or noisy. /USB ] switch set appropriately?  Is the microphone connected to a [MIC/LINE] jack?  When using a condenser microphone, is the [PHANTOM +48V] switch turned on?  Is the [PAD] switch on? Turn this switch off for sources with low output levels, such as microphones.  Is the output signal level for the instrument connected to the mixer appropriate?  When connecting an instrument with an output level of +4 dBu, either turn on the [PAD] switch on a mono input channel or use a stereo input channel.  Where an input channel provides both a XLR input jack and a phone input jack, or a phone input jack and an RCA pin jack, are there connections made at both jacks? Use only one of these jacks.  Are the [GAIN] knobs for each channel, [LEVEL] knobs, [STEREO LEVEL] knob adjusted to appropriate levels?  Are effect or compressor levels too high? Use the [FX] knobs, [FX RTN LEVEL] knob, and [COMP] knobs to lower their levels.  Effects are not applied.  Are the [FX] knobs for each channel adjusted to appropriate levels?  Is the [FX ON] button for [FX RTN] turned on?  Are the [PARAMETER] knob and [FX RTN LEVEL] knob adjusted to appropriate levels?  Speaking voices are not clear.  Is the [HPF] switch turned on?  Is the equalizer ([HIGH]/[MID]/[LOW]) adjusted appropriately?  No mixer monitor signal is output.  Are powered speakers connected to the [MONITOR OUT] jacks? Use the [MONITOR/PHONES] knob to adjust the signal output from the [MONITOR OUT] jacks.  Left and right levels are different for a stereo signal input.  Is [PAN] set to the center? If panned to the center, try reversing the left and right input connections. If, after switching the left and right connections, the side with the low volume level also switches, check the instrument or device that is the source of the signal.  Are you using the same type of cable to connect both the left and right input signals? Cables with built-in resistors will attenuate the signal.  The sound level is unstable and inconsistent.  Is the compressor level set too high? Use the [COMP] knob to lower the level.  The volume of audio play-back from a computer need to be adjusted.  Use the “Attenuator Function”. For details, see page 16.
