The cause of your amplifier’s thermal protection state should be determined and corrected as soon as possible. Without correction, the Thermal Protection circuit will typically reactivate. 3. Fuse Protection The high-voltage power supplies of your Sing Easy amplifier are protected by a fuse.

You may connect the bare wire from your speaker to the output terminal to prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.
1. Connect the speakers, microphone and music player to the PA Series, 2. Power on all audio output devices then power on the PA Series. 3. While playing back audio, slowly increase the volume of the PA Series to the desired listening level.
Connect the PA Series to the AC mains power source (power outlet) with the supplied AC power cordset. First, connect the IEC end of the cordset to the IEC connector on the PA Series; then, plug the other end of the cordset to the AC mains.
8. Do not operate the amplifier with less than the rated load impedance. Due to the amplifier’s output protection, such a configuration may result in premature clipping and speaker damage. Remember: Sing Easy is not liable for damage that results from overdriving other system components.
