Normal Operation
Constant Bright Blue
Indicates the audio signal is clipping. Reduce volume level to help
eliminate potentially damaging audio signals from reaching the speakers.
Flashing Blue
The temperature of the individual amplifier heatsink is above 95˚C. If this
occurs, the channel will not pass audio. The channel status LED will return
to constant blue when the temperature of the amplifier card returns to
normal. Then the channel will automatically resume passing audio.
All Channels Flashing
Blue
The temperature of the chassis is above 58˚C, and the amplifier will no
longer pass audio. After the chassis temperature returns to normal, all the
channel status LEDs will return to constant blue and the amplifier will
resume normal operation.
