Troubleshooting■Power doesn’t come
on.
❑
Be sure that you are using the supplied power cord, and that it is correctly
connected to the AC IN connector and plugged into a working power out-
let.
■Power suddenly went
off.
❑Check whether the vents at the front and rear of the unit are blocked.
The EMX unit may overheat if the vents are blocked. If the unit overheats,
the power may automatically go off. Wait for the unit to cool down, and
then turn the power back on.
■Sound suddenly
stopped.
❑
Check whether the vents at the front and rear of the unit are blocked.
The EMX unit may overheat if the vents are blocked. If the unit overheats,
it may cut off the output to the internal amp until things cool down.
■No sound. ❑
Are microphones, external devices, and speakers connected correctly?
❑
Are the GAIN controls, channel faders, ST master fader, and AUX1/2 fad-
ers set to appropriate levels?
❑Is the POWER AMP switch set correctly? When outputting a stereo sig-
nal, set it to the L/R position.
❑Check that the speaker cables are not shorted.
❑If the above checks do not identify the problem, call Yamaha for service.
(Refer to the end of this manual for a list of Yamaha dealers.)
■Sound is faint, dis-
torted, or noisy.
❑
Are the GAIN controls, channel faders, ST master fader, and AUX1/2 fad-
ers set to appropriate levels?
❑
Check that the [26 dB] switches on channels 1 to 8 are set correctly.
❑
On channels 1 to 8, be sure that you have not connected to both INPUT A
and INPUT B. (On each of these channels you may use one input or the
other, but not both.)
❑
Is the input signal from the connected device set to an appropriate level?
❑You may be applying excessive digital effect. Check your effect settings.
■No effect is applied. ❑
Check that the EFF1/2 knob on each channel is correctly adjusted.
❑Be sure that the internal effector’s ON switch is turned on.
❑
Check that the EFF1/2 RTN fader is correctly adjusted.
■The sound from the
speakers seems dull.
I want a more forceful
sound.
❑Try turning on the YS Processing switch.
❑Try turning on the MAXIMIZE ON switch.
❑
Adjust the equalizers (HIGH, MID, and LOW knobs) on each channel.
❑Adjust the graphic equalizers.
■I want spoken words
to be heard more
clearly.
❑Check that the switches (high pass filters) for the relevant channels
are turned ON as appropriate.
❑
Be sure that the YS Processing switch is turned off.
❑
Adjusting the equalizers (HIGH, MID, and LOW knobs) on each channel.
❑
Adjusting the graphic equalizers.
■I want to output a mon-
itor signal through
speakers.
❑
Connect a powered speaker to the AUX1/2 jacks. Then adjust the
AUX1/2 signal by adjusting the channel AUX1/2 controls and the AUX1
and AUX2 faders.
❑
If you want to send the monitor signal to SPEAKERS A jack, set the
POWER AMP switch to the AUX1/MONO position. (Note that in this case
the A jack will output the monitor signal, and the B jack will output a mix of
the stereo L and R signals.)
■I want to initialize the
GEQ and digital effect
settings.
❑
Turning on the power while holding the GEQ ON switch and MAXIMIZE
ON switch restores the initial factory settings for GEQ, Effects, Feedback
Suppressor, and MAXIMIZE.
