The EE1 network noise isolator is designed to sit discreetly between ethernet cables within a streaming audio/video system and can drastically reduce noise whilst allowing digital signals to pass unhindered.
Digital signals are robust but are often accompanied by a degree of noise, usually transferred from home network devices.
The EE1, like the EE 8Switch and 16Switch, continues our efforts to prevent noise from affecting music/image data and system performance.
Installation options
For optimum results please ensure the > direction markings on the EE1 unit follow the direction of the music/data signal.

If using cables of varying quality we suggest connecting the superior model/s as far along the signal path as possible, between EE1 and the server/streamer (system type 1) or between EE1 and streamer (system type 2).

If further noise-reduction/enhancement is desired, a second EE1 can be installed between router and network switch.

Installing the EE1 will require an additional ethernet cable.
We recommend using Chord Company streaming (Ethernet) cables throughout your streaming audio system.
