Trust what you hear, your perceptions are unique to you.

iEARTH earth box actually works to achieve improved sound performance of your audio system through noise reduction. It's not the type of noise you can detect by putting an ear to a speaker when the music's not playing. Removing the crud caused by electrostatic fields makes music sound more dynamic, more musical and with greater clarity.

Noise - Think Outside the Box

​

• In its broadest definition, noise is any undesired signal

• Analog signals accumulate noise as they flow through system equipment and cables

• Once noise is added, it's essentially impossible to remove it without altering or degrading the original signal. Therefore, noise must be prevented along the entire signal path.

• Signal INTERFACES are generally the danger zone, rather than the equipment itself.

Understanding Noise in Your Audio System

• Defining Noise: At its core, noise is any unwanted signal that interferes with your audio experience.

• The Journey of Analog Signals: As analog signals traverse your system's equipment and cables, they pick up noise, accumulating unwanted signals that degrade audio quality.

• The Challenge of Removing Noise: Once introduced, noise is nearly impossible to remove without changing or diminishing the original signal's integrity. The key is to prevent noise from entering the signal path in the first place.

• Where Noise Finds Its Way: Often, the most vulnerable points for noise intrusion are signal interfaces, not necessarily the equipment itself.

 

The iEARTH Earth Box plays a crucial role in preserving the purity of your audio system's signal, ensuring that what you hear is as true to the original recording as possible.

 

Types of Signal Noise and Their Effects

​

1. Digital Noise:

• Origin: Arises from digital devices and circuits, such as DACs, digital streamers, or computers. Generated by the binary switching operations in digital processing.

• Effect: Can affect even fully analog devices like tube amplifiers through interconnected cables, leading to less pure sound, reduced clarity, and increased harshness.

2. Analog Noise:

• Origin: Emanates from electromagnetic interference (EMI) from electronic devices, thermal noise from resistors, and mechanical vibrations.

• Effect: Adds hiss, hum, or static to audio output, detracting from fidelity in turntables and reducing signal-to-noise ratio in amplifiers.

3. Ground Loop Noise:

• Origin: Occurs with multiple grounding paths in an audio system, creating loops that induce noise.

• Effect: Manifests as a low-frequency hum or buzz, problematic in systems with complex interconnections.

4. Video Signal Noise:

• Origin: Relevant in systems combining audio and video devices, stemming from complex processing in video devices and cables, such as HDMI.

• Effect: Can degrade audio quality through shared connections and power supplies, introducing interference similar to digital noise.

5. Network Signal Noise:

• Origin: Generated by network devices and cables, especially in environments with high-frequency data transmission and Wi-Fi signals.

• Effect: Can introduce jitter and latency in streamed audio content, affecting timing accuracy and leading to a less stable soundstage.

6. Turntable (Phono) System Noise:

• Origin: Arises from the mechanical nature of turntables and the electrical signal processing in phono preamps. Includes motor noise, belt vibrations, and electrical noise from the cartridge.

• Effect: Adds pops, clicks, and a background hum to the audio output, potentially overshadowing the nuances of the vinyl playback and reducing the overall warmth and depth of the sound.
