To Next PageTo Next PageWhy is the sound distorted on my Crown Amplifier?
If the sound from your Crown Amplifier is distorted, it might be due to incorrect loading settings or a wrongly set Stereo/Bridge mode switch. Verify that both the loading and mode switch are properly configured. Alternatively, the input signal might be too high, causing an overload. In this case, reduce the amplifier level controls or the input signal until the clip light turns off.
What to do if the power indicator is off and mains indicator is off on Crown DCi 4|300N Amplifier?
If the power and mains indicators are off on your Crown Amplifier, it could be due to several reasons. First, the power supply fuse might have tripped, requiring you to check and replace it. Second, the amplifier might have lost AC power, so verify the AC power source. Lastly, ensure the amplifier is properly plugged into the power receptacle.
Why is the thermal indicator on my Crown DCi 4|300N Amplifier?
If the thermal indicator is on, it means your Crown Amplifier is overheating and is becoming too hot for safe operation. Allow the amplifier to cool down. Then, check for loads less than 2 ohms and excessive input levels. Also, ensure that there is proper ventilation and the mode-switch is correctly set.
What to do if my Crown DCi 4|300N has power but no sound?
If your Crown Amplifier has power, the power LED is on, the amp is receiving a signal, and the signal indicator is flashing, but there is no sound, consider these possibilities: * Speakers might not be connected: Connect the speakers. * There may be an open circuit due to speaker failure: Check the speaker for failure. * The channel might be set to Sleep mode or Power Save mode: Disable Sleep mode or Power Save mode.
What does it mean if the fault indicator is flashing on my Crown DCi 4|300N?
If the fault indicator is flashing on your Crown Amplifier, it indicates a problem such as a temperature above 98C, DC/LF protection engaged, HF detect, or an output short circuit detected. Check these conditions and attempt to resolve them before sending the amp for service.
Why is the power indicator flashing on my Crown DCi 4|300N Amplifier?
If the power indicator is flashing on your Crown Amplifier, it means the AC line voltage has dropped below 10% or risen above 10% of the nominal line voltage of the power supply. Stabilize the AC line voltage to resolve this issue.
What to do if there is no input signal on Crown Amplifier?
If the signal indicator is not flashing on your Crown Amplifier, even though audio is applied and the channel is ready, it may be because the input signal level is very low. Try increasing the input signal level.
How to turn on Crown DCi 4|300N Amplifier if the power indicator is off?
If the power indicator is off, but the mains indicator is on for your Crown Amplifier, the amplifier’s power switch is likely turned off. Turn the amplifier’s power switch on.
Why is the bridge LED lit on my Crown DCi 4|300N?
If the Bridge LED is lit on your Crown Amplifier, the amplifier is in bridge-mono mode. Verify that the amplifier is intentionally set to bridge-mono mode.
