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.
