The Furman SS-6B is a deceptively simple piece of equipment. At first glance, it might seem counterintuitive: a power conditioner that adds noise. But the reality is far more nuanced, and understanding its function is key to appreciating its value in a professional audio setup. This isn't about injecting unwanted noise; instead, it's about strategically introducing a specific type of noise to mitigate a far greater problem: ground loops.

Understanding Ground Loops: The Silent Audio Killer

Ground loops are a common issue in audio setups, particularly those with multiple interconnected components. They occur when there are multiple paths to ground, creating a circulating current that manifests as a low-frequency hum or buzz in your audio signal. This hum can be incredibly frustrating, often requiring significant troubleshooting to locate and eliminate.

The SS-6B's Solution: Noise to Neutralize Noise

The Furman SS-6B addresses ground loops through a clever technique: it injects a small amount of high-frequency noise into the power line. This noise, while inaudible to the human ear, acts as a "drowning" mechanism. It effectively masks the low-frequency hum caused by the ground loop, resulting in a cleaner, clearer audio signal. The injected noise is carefully controlled and designed to not negatively impact the audio quality.

More Than Just Hum Reduction

While hum reduction is the SS-6B's primary function, it also offers other benefits often associated with high-quality power conditioners:

• Surge Protection: The unit provides basic surge protection, safeguarding your valuable equipment from power spikes and surges.
• Voltage Regulation: It offers some degree of voltage regulation, helping to ensure a stable power supply to your audio components. This is crucial for maintaining consistent performance and preventing damage.

Is the Furman SS-6B Right for You?

The Furman SS-6B is a valuable tool for professionals and serious hobbyists facing persistent ground loop issues. However, it's important to consider that it's not a universal solution. If your hum or buzz is caused by a faulty component or a poorly grounded system, the SS-6B won't magically fix the underlying problem. It's best used as a preventative measure or a targeted solution to address known ground loop issues. Before purchasing, thoroughly diagnose the source of your noise problems to ensure the SS-6B is the appropriate solution.

Conclusion

The Furman SS-6B represents a sophisticated approach to a common audio problem. By strategically adding a small amount of high-frequency noise, it effectively eliminates the often-troublesome low-frequency hum caused by ground loops. Its additional surge protection and voltage regulation capabilities further enhance its value as a component in a professional audio setup. While not a cure-all, for persistent ground loop issues, the Furman SS-6B is a powerful tool worth considering.
