Troubleshooting Frequently asked questions are posted on the Yamaha Pro Audio website: http://www.yamahaproaudio.com/ Power does not turn on; panel LEDs and the LCD display do not light. ❍ 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 correctly? 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, external 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? Troubleshooting ❍ 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? Owner's Manual 53
