Eliminate Network Noise from Your Streaming Audio

The English Electric EE1 Network Noise Isolator is a high-performance, inline ethernet filter designed to drastically reduce the digital noise that plagues modern streaming audio and video systems. While digital audio signals are incredibly robust, they are almost always accompanied by high-frequency electronic noise generated by household routers, smart devices, and network switches.

The EE1 sits discreetly between your network cables, filtering out this damaging background “hash” while allowing the digital music data to pass through completely unhindered.

Passive, Self-Powered Innovation

Engineered by the experts at Chord Company, the EE1 features a unique passive design that requires no external power supply. Instead, it utilizes targeted common-mode filtering to capture unwanted noise frequencies and efficiently convert them into harmless heat, dissipating it safely through its machined aluminum chassis.

Galvanic Isolation for Pure Data Delivery

To ensure the highest level of signal integrity, the EE1 employs advanced galvanic isolation. By breaking the direct electrical path between your home network and your sensitive audio components, it effectively blocks low-frequency hum and dramatically attenuates high-frequency interference. With less noise entering your streamer or DAC, your equipment performs less error-correction, resulting in a noticeably cleaner, more relaxed, and open musical presentation.

Key Performance Features:

• Targeted Noise Filtering: Actively targets and reduces both low and high-frequency network noise.
• Passive & Plug-and-Play: Self-powered design means no extra power cables or added system complexity.
• Robust Aluminum Casework: Protects internal components from external electronic noise and microphony.
• Modular Upgradability: Multiple EE1 units can be used in a single network (e.g., one at the router and one before the streamer) for cumulative performance benefits.

Installation Tips for Best Results:

The EE1 is highly versatile and can be placed anywhere along your network line. For optimum performance, ensure the directional arrow > on the chassis follows the direction of the data signal toward your player.

For the ultimate fidelity upgrade, we recommend placing the EE1 just before your network streamer or music server, utilizing a high-quality streaming cable (such as a Chord Company C-Stream or Shawline) from the EE1’s output into your component.
