❍ Is the CL's POWER switch turned on?
❍ Is the power cable connected to a proper AC outlet?
❍ Is the power cable plug inserted all the way — has it
clicked and locked in securely?
➥ If the power still does not turn on, contact your Yamaha
dealer.
The unit is not receiving an input signal.
❍ Did you correctly set the UNIT ID and the DIP
switches on the I/O rack connected to the CL before
turning on the power to the devices?
❍ Are the settings in the DANTE SETUP screen on the
unit specified correctly?
❍ Is a signal being input from an external device?
❍ Is the SIG indicator on the I/O rack lit?
❍ If a phantom-powered microphone is connected to the
CL unit, are the I/O rack's the [+48 MASTER] switch,
CL's [+48V MASTER] switch, and [+48V] button of
each channel set to on?
❍ Is the GAIN of the internal head amp, external head
amp, or I/O rack set to an appropriate level?
❍ Is the input port patched to an input channel?
❍ Is the [ON] key indicator of the input channel lit?
❍ Is the fader of the input channel raised?
❍ Is the EQ attenuator raised?
❍ Could the insert be turned on even though it has not
been specified correctly?
❍ If you are using an optional I/O card, is it installed cor-
rectly?
Sound is not output from headphones or the
MONITOR OUT jacks.
❍ Is the [PHONES] knob or [MONITOR LEVEL] knob
set to an appropriate volume?
❍ Is the monitor fader set to an appropriate level?
❍ Has the monitoring source been selected?
❍ Could the DIMMER be applied to the signal?
➥ Press the MONITOR button, then check the MONITOR
area on the display.
The sound level is too low.
❍ Is the GAIN or digital gain on the head amplifier, exter-
nal head amp device or I/O rack set to an appropriate
level?
❍ Are the input channel faders raised?
❍ Could the EQ gain be turned down excessively?
❍ Are EQ's attenuators raised?
❍ Could the GATE/COMP threshold or ratio setting be
set to an extreme value?
❍ Are the output channel faders raised?
❍ Check the level in the corresponding METER function
screens.
❍ Is the channel fader assigned to a DCA group raised?
❍ Could MUTE MASTER be turned on for the channel
assigned to a MUTE group?
Sound is distorted.
❍ Is the word clock set correctly?
❍ Is the GAIN of the internal head amp, external head
amp, or I/O rack set to an appropriate level?
❍ Could the analog gain have been too low while the Gain
Compensation is turned on?
❍ Could the digital gain be set to an extremely high set-
ting?
❍ Could the input channel fader be raised too high?
❍ Could the STEREO channel fader be raised too high?
❍ Could the EQ gain be set to an extremely high setting?
❍ Could the latency have been too low in the DANTE
SETUP screen?
Sound is output even though it is not patched to
an output channel.
❍ Could you have assigned an input channel to direct
out?
❍ Could you have assigned an output channel as the
insert out?
The volume of a specific channel rises and falls.
❍ Could DYNAMICS1/2 be set to ducking or to an
extreme parameter value?
Operating a fader does not control the level as
you expect.
❍ Could the function access area indicate MIX/MTRX
ON FADER? And could SENDS ON FADER mode be
engaged?
Only the sound of a specific channel is heard from
the MONITOR OUT or PHONES jack.
❍ Could a [CUE] key be on?
Noise occurs from an externally connected
recorder or other device.
❍ Is the word clock set correctly?
❍ Could the input signal be unsynchronized?
❍ Could the oscillator or talkback be turned on?
High frequency range is attenuated.
❍ Could emphasis be applied? This problem will occur if
the input signal status does not match the emphasis
data.
❍ Could EQ be applied?
