Why is the thermal indicator on my Crown CTs 1200 Amplifier?
If the Crown Amplifier is overheating, allow it to cool down. Make sure that the loads are not less than 2 ohms, and that the input levels aren't excessive. Also, verify that the ventilation is sufficient and the mode-switch setting is correct.
What to do if my Crown CTs 1200 Amplifier has distorted sound?
If your Crown Amplifier's sound is distorted, check if the load is wired correctly and that the Stereo/Mono mode switch is set correctly. Also, if the input is overloaded by a signal level that is too high, turn down your amplifier level controls, or turn down the input signal, until the clip light goes out.
How to fix a Crown CTs 1200 Amplifier when the power indicator is off?
If the power indicator is off on your Crown Amplifier, it could be due to several reasons. The amplifier might have lost AC power, or the Power switch might be off. Ensure the amplifier is properly plugged into the power receptacle. If the amplifier output level is too high, allow the unit to cool, turn down the Level controls, and press the Reset Switch on the back panel.
What to do if Crown CTs 1200 has no sound but has power?
If there is no sound from your Crown Amplifier, even though it has power, the Power LED is on without flashing, and the amp is receiving an input signal while the Signal indicator is flashing, check the speaker connections. The speakers may not be connected, or there may be an open circuit due to speaker failure. Also, check for a short on the amplifier output by disconnecting your speakers from the affected channel(s) one by one to determine if one of the loads is shorted.
Why is the power indicator flashing on my Crown CTs 1200 Amplifier?
If the power indicator on your Crown Amplifier is flashing, it means that the AC line voltage has dropped below 20% or has risen above 10% of the nominal line voltage of the power supply.
What to do if Crown CTs 1200 Amplifier has no input signal?
If your Crown Amplifier has no input signal and the signal indicator isn't flashing even though audio is applied and the channel is ready, it could be because the input signal level is very low, or the level controls are turned down.
What does it mean if the fault indicator is flashing on my Crown Amplifier?
If the Fault indicator is flashing on your Crown Amplifier, the amplifier channel has stopped operating. Refer the unit to an authorized Crown Service Center.
Why is the data indicator not flashing on my Crown CTs 1200?
If the Data indicator is not flashing on your Crown Amplifier, even though the PIP module is installed and the host computer IQ software is active, the cable between the computer and the PIP module may be broken or not connected.
