![]() If operating at lower impedance loads, consider reducing the number of speakers or using higher impedance speakers.Excessive heat in the room can impact the amplifier's performance and cause overheating.Ensure the operating environment temperature is within the specified range (refer to the user manual).Avoid stacking other equipment on top of the amplifier that could obstruct airflow.Verify that the AHB2 is placed in a well-ventilated area with sufficient airflow around it.Check for loose or faulty connections at both the AHB2 and speaker ends.Ensure the speaker cables are of sufficient gauge and quality.Inspect speaker cables and connections:.Using speakers with impedance below the recommended level can cause performance issues or even damage the amplifier.Verify that the speakers' impedance matches the recommended load impedance of the AHB2 (3 ohms and higher).Adjust the AHB2's input sensitivity switch if necessary.If using a preamplifier or other device with volume control, ensure the gain setting is suitable for the desired output level.Adjust the source device's volume level to an appropriate level to prevent distortion.Check the output level of the audio source device connected to the AHB2.If possible, test different cables to eliminate the possibility of a faulty cable causing the issue.Try connecting a different audio source to the AHB2 to rule out issues with the original source.Test alternative audio sources and cables:.Check the speaker connections at the speaker end to ensure they are secure.Ensure the speaker cables are properly connected to the AHB2's speaker output terminals. ![]()
