Chord EE1 – High-Performance Ethernet Network Noise Isolator

The Chord EE1 is an innovative Ethernet network noise isolator developed by Chord Company to enhance the performance of streaming audio and video systems. Designed for hi-fi and high-end audio applications, the EE1 is installed between two Ethernet cables to effectively reduce network noise while preserving the integrity of the digital signal.

Using galvanic isolation, advanced EMI filtering and proprietary Chord Company technologies, the Chord EE1 minimizes both low-frequency and high-frequency interference generated by routers, switches, NAS drives, servers and other network-connected devices. The result is cleaner, more detailed and more natural sound reproduction, with improved transparency, enhanced soundstage precision and reduced digital harshness.

The device operates in a completely passive configuration and requires no external power supply. Its sophisticated internal circuitry converts unwanted noise into heat without restricting or altering Ethernet data transmission. Thanks to its compact design and precision-machined aluminum chassis, the Chord EE1 integrates easily into any premium streaming audio or home cinema system.

The advanced Chord EE1 PLUS version introduces further improvements through Chord Company’s proprietary ARAY technology, optimized common-mode filtering and an even more refined internal architecture. Ideal for streamers, network DACs, music servers, audiophile switches and high-performance AV systems.
