• Is the power cable connected properly? (page 6)
• Is the [POWER] switch properly engaged? (page 7)
• If you've checked all possible causes and the power still won't come on, refer the
problem to your Yamaha dealer.
• Are the input cables properly connected?
• Are the source devices delivering an appropriate signal? Check the SIG indicators
on the appropriate channels.
• Have you executed the Quick Setup function? Did you change any patch settings via
the AVS-ESMonitor application after executing the Quick Setup function?
• Are the AVS-ESMonitor patch settings appropriate (Net Patch or I/O Patch page)?
• Is the head amplifier gain set to an appropriate level?
• If a condenser microphone is being used, is the [+48V MASTER] switch ON?
• If a condenser microphone is being used, is phantom power for the corresponding
channel(s) turned ON?
• Is the head amplifier gain set to an appropriate level?
• Are the output cables properly connected?
• Have you executed the Quick Setup function? Did you change any patch settings via
the AVS-ESMonitor application after executing the Quick Setup function?
• Are the AVS-ESMonitor patch settings appropriate (Net Patch or I/O Patch page)?
• Is output muted at the digital mixing console?
• Refer to page 17 for information on error messages that might be displayed during
execution of the AVS-ESMonitor Quick Setup function.
• Did you make the appropriate Head Amp Controller setting when executing the
Quick Setup function? Did you change the Serial Communication Mode setting after
executing the Quick Setup function?
• Is the AVS-ESMonitor Serial Communication Mode set properly? (page 16)
• If you will be controlling the head amplifiers via the 9-pin D-sub REMOTE connector
on a digital mixing console, is the mixing console's REMOTE connector properly
connected to the HA REMOTE connector on the MY16-ES64 card (Primary Mas-
ter)? (page 14)
• If you will be controlling the head amplifiers via a mixing console expansion slot, is
the EXTERNAL HA display COMM PORT parameter set appropriately? (page 14)
• Set up the digital mixing console input patching in sequential 8-channel groups for
the slot inputs (CH1–8, CH9–16, etc.). This makes it easy to select input channels
on the external SB168-ES units for remote head amplifier control.
