Solutions for Audio Problems

Audio problems happen, they can and will. That's why it's important to know that audio solutions are available to remedy most of these situations. Understanding your gear when creating pro audio recordings is essential when those problems do arise, and Performance Audio is a great resource to learn more about your gear and find the solutions for your audio needs.

When to Use a Hum Eliminator

Hum eliminators are a great solution if you're struggling with a buzzing or humming noise in your sound system. Humming and buzzing is usually a result of a ground loop. The ground loop hum occurs when there's a difference in electrical potential at the grounding points of your sound system. Inserting a hum eliminator between the two pieces of equipment where the buzzing sound is coming from will usually solve the problem. In-line versions work with a single cable connection, whereas multi-channel hum eliminators have multiple XLR or 1/4-inch connections.

What Are Matching Transformers?

If you're setting up a large sound system, electrical impedance is a significant concern, and can cause problems such as echoes or colorations from the mismatched circuitry. If you want your audio equipment to reach its full potential, you need to eliminate impedance issues. You can do this by matching load impedance to ensure optimal power transfer between your audio devices. Matching transformers keep your impedance levels balanced between your audio connections, and eliminate background noises and distortion.

What Is a Direct Box (DI Box)?

Direct boxes are often referred to as "DI" boxes. The DI stands for "Direct Injection" as the main purpose of a Direct Box is to convert unbalanced and/or high impedance instrument signals into a low impedance balanced format suitable for direct connection to a mixing console's mic input - without the use of a microphone. Additionally it isolates electronic equipment on stage from the mixing console which can help reduce interference and noise. Direct Boxes are available in both active and passive variants.
