Troubleshooting
Check the following items before contacting a Yamaha dealer. 
If the symptoms are not improved, contact your nearest Yamaha dealer.

Power does not come on.
Did you firmly and securely connect the power cord?

Power shuts down suddenly.
Are the vents of the mixer blocked?
Since inadequate ventilation can result in overheating the mixer, the power may be turned off automatically to prevent overheating. Ensure proper ventilation for cooling, and then turn on the power again.

No sound is heard.
Did you connect the mixer's [SPEAKERS L/R] jacks and the speakers' input jacks using the proper speaker cables?
Did you firmly and securely connect the speaker cables?
Is the [POWER] LED flashing at intervals?
There may be a short in the speaker cable or the connection may be faulty. Check that the speaker cable is not scratched and is connected properly to the mixer, and then turn the power on again.
For channels 7/8, are both phone and RCA-pin jacks connected at the same time? Or, for channels 9/10, are both phone and stereo-mini jacks connected at the same time?
The phone jack has priority for channels 7/8 and the stereo-mini jack has priority for channels 9/10.
Is the [POWER] LED flashing continuously?
If the internal power amplifier section is excessively overloaded, the amplifier will be muted for protection. The mixer will automatically reset itself after a while.

Sound is distorted or noise is produced.
Are the [LEVEL] controls of all relevant channels and/or the [MASTER LEVEL] control set too high?
Is the [(OFF) MIC/(ON) LINE] switch of the corresponding channel set to "(OFF) MIC"?
If the input level from the source is high, setting the [(OFF) MIC/(ON) LINE] switch to "(OFF) MIC" may result in distorted sound. Set the switch to the "(ON) LINE" position.
Is the volume of the device connected to the mixer too high?
Lower the volume of the external device.
Is the speaker cable or power cord located near the input cables?
Please keep speaker cables and the power cord away from the input cables.

Sound is not loud enough.
Are the [LEVEL] controls of all relevant channels and/or the [MASTER LEVEL] control set too low?
Is the [(OFF) MIC/(ON) LINE] switch of the corresponding channel set to "(ON) LINE"?
Turn the [LEVEL] control to the minimum (zero). Next, set the switch to the "(OFF) MIC" position, and then slowly raise the [LEVEL] control.
Is the volume of the device connected to the mixer too low?
Raise the volume of the external device.
Is the [PHANTOM (CH1/2)] switch set to on when using a microphone that requires phantom power?

The high sounds and low sounds are unbalanced.
Are the equalizer controls raised or lowered too much?
Set the equalizer controls to the center position.
