Activates and deactivates standby mode when the DD-8 amplifier is connected to AC power.
When the DD-8 is connected to AC power, the standby button LED will glow RED indicating that the
unit is in the standby mode. In this state, the power amplifier section is not activated and the unit
consumes minimal AC power. Pressing the standby button from this state will activate the power
amplifier section and the standby button LED will glow BLUE indicating that the DD-8 is powered on.
2. Channel Status Indicator LED's
Indicates the status of each of the eight amplifier channels when the DD-8 is active.
When a channel is active, its LED indicator will glow BLUE. If the channel is in standby, the LED will be
off. If a channel has a fault, the LED will blink BLUE indicating the presence of a short or some other
problem related to that channel. (See the troubleshooting section for more information.)
