If the power indicator is off but the power switch is illuminated, it means that the amplifier’s power switch is off. Turn on the power switch to resolve this issue.
What to do if the Crown I-Tech Amplifier power indicator is off and power switch is not illuminated?
If the power indicator and power switch are not illuminated, it indicates a loss of AC power or that the amplifier isn't properly connected. Here's what you should do: 1. Check the power source to ensure it is active. 2. Verify that the amplifier is correctly plugged into the power receptacle. 3. Check the rear-panel breaker and turn it on, if it is off.
Why is the Crown Amplifier power indicator flashing?
A flashing power indicator means the AC line voltage is outside the acceptable range. Check the AC line voltage to ensure it's within 15% of the rated range.
