Other

 The power does not come on.

 No sound is output.

 The sound is low, distorted, or noisy.

 Effects are not applied.

 Speaking voices are not clear.

 No mixer monitor signal is output.

 Left and right levels are different for a stereo signal input.

 The sound level is unstable and inconsistent.

 The volume of audio play-back from a computer need to be adjusted.

 Is the mixer connected to an independent power source (generator, etc.) or a power strip with switches?

Check that the power of that device is turned on.

 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 /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?

Phone

Phone connectors are available in TRS and TS types. TRS types are used for stereo headphone jacks, insert jacks, and also for carrying balanced signals in many cases. TS types are used to carry unbalanced signals -for example, electric guitar cables.

RCA Pin

This type of unbalanced connector is most commonly found on home audio and video equipment. RCA type pin jacks are often color coded: white for left audio channel and red for right audio channel, for example.
