ED 120 Coaxial 75 Ohm Digital Cable

ED 120 is the fourth generation descendant of the original Omniwire coaxial cable first introduced in 1993. Accurate transmission of S/PDIF and AES3 digital audio signals demands tight adherence to the 75 ohm characteristic impedance standard in order to minimize reflections and jitter. The required level of manufacturing precision can only be achieved through careful selection of conductor and dielectric materials.

ED 120 is terminated with industry-leading low return loss BNC connectors. Custom BNC > RCA adapters facilitate connection to components with RCA S/PDIF jacks, offering performance that actually surpasses that of directly-terminated RCA connectors. An integral EMC filter elevates performance even further, exemplifying Empirical Design’s commitment to innovative “outside the box” exploration.

ED 120 delivers state-of-the-art digital signal transfer at an eminently rational price.
