Eliminate Annoying White Noise in Your AV Receiver Speakers

Jan 23, 2024

Experiencing white noise in your speakers when using an AV receiver can be extremely frustrating and can hamper your audio enjoyment. White noise is a sound that contains every frequency a human can hear, and it can vary in volume. It is typically heard as static, hissing, humming, or buzzing, and can drown out the audio you are trying to listen to. There are several solutions to eliminate white noise in speakers on an AV receiver.

  1. Check Your Connections: Ensure that all cables and connections are secure, as a loose connection can cause white noise. This includes both speaker wires and input cables. Ensure that your speakers' impedance matches the receiver's output impedance as well, to avoid impedance mismatches, which can result in white noise.

  2. Change Cables: Damaged or low-quality cables can produce white noise. Swap your current cables with higher-quality cables, preferably ones which are shielded, as this can help block out external interference that may be causing the white noise.

  3. Use a Power Strip with a Built-In Surge Protector: Electrical interference from other devices sharing the same power source can cause white noise. A power strip designed for audio and video equipment can help reduce interference, providing cleaner power to your AV receiver and speakers.

  4. Move Your Receiver: Relocate your AV receiver away from other electrical appliances that may be causing interference, such as televisions, computers, or gaming consoles.

  5. Install a Ground Loop Isolator or HumX: A ground loop can cause white noise by creating voltage differences between audio components. A Ground Loop Isolator can break the ground loop and eliminate the noise, while a HumX device filters out unwanted low-frequency noise.

  6. Upgrade Your AV Receiver: If none of the above solutions work, you may need to upgrade to a newer AV receiver model with better noise reduction capabilities, or have it serviced to diagnose and repair any potential internal issues.

By following these recommendations, you can eliminate white noise from your speakers and enjoy better audio quality from your AV receiver.
