5. Connect the AC Power Cord
The AC input connector accepts standard IEC input cables. Use a grounded cable that is
appropriate for your location. The AC input is auto ranging and may be used internationally without
changing any settings or fuse sizes. Fuses are located in a drawer at the top of the AC input
connector.

 Press the power button to turn the unit on or off.
7. Check the Status Indicators
The amplifier has the following status indicators:
 POWER - Power-status indicator, On = Normal, Flashing = Fault
 CLIP (one per channel) - Audio-clip indicator, Flash = Clip, Off = Normal, On = Fault
 TEMP (one per channel) - Over-temperature indicator, Off = Normal, On = Fault
 MUTE (one per channel) - Channel-mute indicator, Off = Normal, On = PROTECT
POWER - Power Status Indicator
 Off = Power is Off
 On = Normal Operation
 Flash = Fault Condition, Power Supply has Shut Down
CLIP - Audio Clipping Indicators
 Off = Normal
 Occasional Flash = Some Clipping is Occurring
 On = Fault Condition, Excessive Clipping has Occurred
TEMP - Over-Temperature Indicators
 Off = Normal
 Left On = Fault - Left Channel Overheated
 Right On = Fault - Right Channel Overheated
 Both On = Other Fault Conditions
MUTE - Audio Mute Indicators
 Off = Normal
 Both On During Start Up or Shut Down = Normal, Audio is Muted
 Both On = PROTECT Mode, a Fault has Occurred, Audio is Muted
Note: Audio will automatically mute on startup and shutdown to protect the speakers and eliminate
unwanted transients.
