Why is the bridge LED lit on my Crown Amplifier?
- BBryan HartAug 14, 2025
If the Bridge LED is lit, it indicates that the amplifier is in bridge-mono mode. Verify if the amplifier should be in bridge-mono mode.

If the Bridge LED is lit, it indicates that the amplifier is in bridge-mono mode. Verify if the amplifier should be in bridge-mono mode.
Why is my Crown Amplifier sound distorted?
Distorted sound from your Crown Amplifier can occur if the load is wired incorrectly, the Stereo/Bridge mode switch is set incorrectly, or the input is overloaded by a signal level that is too high. Check the wiring and the Stereo/Bridge mode switch. If the input signal is too high, turn down your amplifier level controls, or turn down the input signal until the clip light goes out.
What to do if my Crown Amplifier has no sound but the power LED is on?
If your Crown Amplifier has power, the Power LED is on but there's no sound, and the signal indicator is flashing, it could be due to several reasons: the speakers are not connected, there is an open circuit due to speaker failure, or the channel has been set to Sleep mode via the Aux port or Power Save mode. Connect the speakers, check for speaker failure, and change the Aux port or Power Save mode settings.
How to fix a Crown DCi 8|300 when both power and mains indicators are off?
If both the power and mains indicators are off on your Crown Amplifier, it could be due to a few reasons. The power supply fuse may have tripped, the amplifier may have lost AC power, or the amplifier might not be plugged into the power receptacle. Replace the power supply fuse, check the power source, and ensure the amplifier is plugged into the power receptacle.
What to do if the thermal indicator is on in my Crown DCi 8|300?
If the thermal indicator is on, the amplifier is becoming too hot for safe operation. Allow the amplifier to cool down. Check for loads less than 2 ohms and for excessive input levels. Also, check for proper ventilation and the proper mode-switch setting.
Why is the fault indicator flashing on my Crown DCi 8|300?
The Fault indicator flashes when the temperature is above 98C, DC/LF protection is engaged, HF detect, or an output short circuit is detected. Check all conditions that might cause the Fault indicator to flash and resolve them before sending the amp for service.
Why is the power indicator flashing on my Crown DCi 8|300 Amplifier?
A flashing power indicator on your Crown Amplifier can mean that the AC line voltage has dropped below or risen above 10% of the nominal line voltage of the power supply, or the amp is in sleep mode as set on the aux port. Check and stabilize the AC line voltage. You can also change the settings on the Aux port to wake up the amp.
How to turn on Crown Amplifier if the power indicator is off but the mains indicator is on?
If the power indicator is off but the mains indicator is on, it means that the amplifier’s Power switch is off. Turn on the amplifier’s Power switch.
What to do if my Crown Amplifier has no input signal?
If there is no input signal and the signal indicator is not flashing, even though audio is applied and the channel is ready, the input signal level may be very low. Increase the input signal level.
