A
Power/Standby LED — A single LED that lights green when the unit is on and active,
and lights amber when:
• The unit is in standby mode, which turns off all outputs from the amplifier although
the amplifier still receives power.
• The unit will not come out of standby when DC voltage is detected. The amplifier
only comes out of standby mode by either resetting the device or powering it down.
NOTE:
Power indicator LED may stay lit amber for a short time after removing the AC
Power Supply. This is normal.
B
Over Temp Indicator — A single LED that lights red when the amplifier has exceeded
the maximum recommended operating temperature. The amplifier recovers once the
unit has cooled down to below the maximum recommended operating temperature.
Power limiting may occur, but it depends on the unit’s temperature.
