Note:

 

 

 

 

 

Constant Bright Blue

Indicates the audio signal is clipping. Reduce volume level to help

 

 

 

When the main power transformer temperature

exceeds 100˚C:

 

 

The temperature of the individual amplifier heatsink is above 95˚C. If this

All Channels Flashing

The temperature of the chassis is above 58˚C, and the amplifier will no

FAQ

What do the constant blue LEDs indicate?

The constant blue LEDs indicate normal operation of the amplifier.

What does flashing blue LED indicate?

Flashing blue LED indicates that the channel will not pass audio due to high temperature, but will resume normal operation once the temperature returns to normal.

How do I troubleshoot if all channels are flashing blue?

If all channels are flashing blue, it means the chassis temperature is above 58C. Once the chassis temperature returns to normal, all the channel status LEDs will return to constant blue and the amplifier will resume normal operation.
