Digital coaxial audio cables are designed for wide bandwidth applications to transport multichannel audio. For maximum performance, Clarus Digital Audio cables are engineered with a proprietary dielectric designed to maintain a consistent 75 Ohm impedance for accurate signal transfer of the digital data. Ultra-pure silver-plated PCCC signal conductors support higher frequency performance by lowering resistance to dramatically increase signal transfer. Shielding is chosen for its immunity to noise and electromagnetic interference. Clarus Digital Audio cables are packaged and sold in each.
