amplier section and the standby button LED will glow BLUE indicating that the DD-8 is powered on.
NOTE: When the status of the DD-8 changes or is powered up from standby mode, there

NOTE: If the trigger input is used on the DD-8, it will override the standby button operation.

problem related to that channel. (See the troubleshooting section for more information.)
