Who is Sigma-X S/PDIF best suited for?
High-performance digital systems using a 75-ohm coaxial S/PDIF connection.
S/PDIF vs. AES/EBU
S/PDIF uses 75-ohm coaxial construction; AES/EBU uses a 110-ohm twinaxial architecture. Match the cable to the component interface.
Technology
Sigma-X S/PDIF combines Shunyata technologies for electromagnetic control, precision impedance, common-mode noise reduction, shielding, and conductor conditioning. Its model-specific 75-ohm coaxial design uses SPC conductors, a 100% braided SPC shield, PTFE dielectric, PMZ, TAPc, dual-element CMode, and KPIP v2 processing.
TAPc
Patent-pending Transverse Axial Polarizer technology couples to electromagnetic fields surrounding signal conductors and is designed to reduce electromagnetic distortion. Sigma-X S/PDIF uses 35 TAPc elements.
PMZ
PMZ is Shunyata's precision production standard for tightly controlling conductor surfaces, dielectric extrusion, and braided-shield geometry to minimize impedance variance.
CMode
CMode is Shunyata's common-mode filtering technology, designed to reduce common-mode noise without the compression effects associated with conventional filtering. Sigma-X S/PDIF uses a dual-element CMode filter.
KPIP v2
Shunyata Research's proprietary Kinetic Phase Inversion Process is applied to conductor and terminal metals. Sigma-X S/PDIF receives four days of KPIP v2 processing.
75-Ohm Coaxial Architecture
Sigma-X S/PDIF uses SPC conductors, a 100% braided SPC shield, PTFE dielectric, and a specified 75-ohm characteristic impedance.
