Troubleshooting

Power won't turn on, panel LEDs or
LCD won't light
Sound is not input
Sound is not output
Sound is not output from
headphones or MONITOR OUT jacks
Insufficient volume
Sound is distorted
Sound is output even though not
patched to an output channel
Operating a fader does not change
the level as expected
Only a specific channel is heard from
the MONITOR OUT or PHONES jack
Noise is present in an externally
connected recorder or device
High-frequency range is lacking
An input signal is being input, but
there's no monitor output
Headroom is restricted, particularly
when EQ boost is applied
Signal is delayed
Can't save scene memories or library
data
Can't transmit/receive MIDI data
When a scene is recalled, some
channels/parameters do not update
When a scene is recalled, it takes time
for the faders to stop
❍ Are the LCD contrast and panel brightness set appropriately?
❍ Is the POWER switch turned on?
❍ If the power still does not turn on, contact a Yamaha service center listed at the
end of the manual.
❍ Is the optional I/O card inserted correctly? (see page 18)
❍ Is the signal from the external device being input?
❍ Is the input port patched to an input channel? (see page 29)
❍ Is the GAIN set to an appropriate level? (see page 32)
❍ Is the EQ attenuator raised? (see page 35)
❍ Is an insert turned on even though it is not assigned correctly?
❍ Is the input channel's [ON] key indicator lit?
❍ Is the input channel's fader raised?
❍ Is the optional I/O card inserted correctly? (see page 18)
❍ Is the STEREO channel's [ON] key indicator lit?
❍ Is the output channel patched to an output port? (see page 31)
❍ Is the [PHONES] knob or [LEVEL] knob set to an appropriate volume?
❍ Is the GAIN set to an appropriate level? (see page 32)
❍ Is the input channel's fader raised?
❍ Could the EQ gain be lowered excessively? (see page 35)
❍ Could the GATE/COMP threshold or ratio be set to an excessive value? (see
page 37)
❍ Is the EQ attenuator raised? (see page 35)
❍ Is the output channel's fader raised?
❍ Check the levels in each screen of the METER function. (see page 23)
❍ Is the wordclock set correctly? (see page 27)
❍ Is the GAIN set to an appropriate level? (see page 32)
❍ Could the input channel's fader be raised excessively?
❍ Could the STEREO channel's fader be raised excessively?
❍ Could the EQ or COMP gain be raised excessively?
(see pages 35–37)
❍ Could the input channel be set to direct out? (see page 33)
❍ Could insert out be assigned to the output channel?
❍ Are the correct channels selected in the LAYER section?
❍ Could the [CUE] key be on?
❍ Is the wordclock set correctly? (see page 27)
❍ Could an unsynchronized signal be input?
❍ Is the oscillator turned on? (see page 45)
❍ Could emphasis be applied? This will occur if the state of the input signal does
not match the emphasis data.
❍ Could EQ be applied? (see page 35)
❍ Could DIMMER be applied?
❍ Is the routing appropriate for the signal you want to monitor?
❍ Use the EQ's attenuator to reduce the level. (see page 35)
❍ Check whether the delay of each channel is set correctly.
❍ Could you be attempting to save a read-only scene/library memory, or a pro-
tected scene? (see page 42)
❍ Is the MIDI PORT selected correctly?
❍ Are the MODE and channel selected correctly on the transmitting and receiving
devices?
❍ Have you assigned an event to the program change?
❍ Could recall safe be specified for those channels/parameters?
❍ Could a fade time have been specified?
