Shunyata Research Sigma-X AES/EBU Cable | 110-Ohm Digital Cable
Shunyata Research Sigma-X AES/EBU is a reference 110-ohm balanced digital cable for AES/EBU connections between compatible digital sources, transports, DACs, and processors. Its twinaxial construction uses OCC copper conductors, a 100% foil shield, fluorocarbon dielectric, gold/copper-contact connectors, TAPc, dual-element CMode filtering, and KPIP v2 processing.
Choose Sigma-X AES/EBU when your components use balanced 110-ohm AES/EBU digital interfaces and you want the Sigma-X approach applied to that specific transmission standard.

Who is Sigma-X AES/EBU best suited for?
Digital systems using the professional balanced AES/EBU interface between transports, streamers, processors, and DACs.
AES/EBU vs. S/PDIF
AES/EBU is a 110-ohm twinaxial interface. Sigma-X S/PDIF is a 75-ohm coaxial design; use the format specified by your components.
Technology
Sigma-X AES/EBU combines Shunyata technologies for electromagnetic control, common-mode noise reduction, transmission-line integrity, shielding, and conductor conditioning. Its model-specific 110-ohm twinaxial design uses OCC copper conductors, 100% foil shielding, fluorocarbon dielectric, 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 AES/EBU uses 35 TAPc elements.
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 AES/EBU 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 AES/EBU receives four days of KPIP v2 processing.
110-Ohm Twinaxial Architecture
Sigma-X AES/EBU uses OCC copper conductors, a 100% foil shield, fluorocarbon dielectric, and a specified 110-ohm characteristic impedance for the AES/EBU interface.
