2. Channel Status LEDs
Indicate the status of each channel as follows:
• Constant blue indicates normal operation.
• Constant bright blue indicates a ≥1% distortion present in
the audio signal. Reduce volume level to help eliminate
potentially damaging audio signals from reaching the
speakers.
• Flashing red indicates that the temperature of the
individual amplifier card is too high. When this occurs, the
channel will not output audio. The LED will light blue
when the temperature returns to normal, and the channel
will automatically resume outputting audio. See Section 3
for troubleshooting information.
• Constant red indicates a fault in the channel. See Section 3
for troubleshooting information.
Note:
When the main power transformer temperature
exceeds 110˚C, the transformer will deactivate, all
channel status LEDs will no longer be lit, and the
standby LED will flash rapidly.
