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 the AES/EBU link between a transport, streamer or processor and a DAC. It uses twinaxial OCC copper construction with a 100% foil shield, fluorocarbon dielectric, gold/copper-contact connectors, 35 TAPc elements, dual-element CMode filtering and four days of KPIP v2 processing.
Choose it when both components have balanced AES/EBU digital connections. For a 75-ohm coaxial link, see Sigma-X S/PDIF. For clock links, see Sigma-X Clock-75 and Sigma-X Clock-50. See all our Shunyata Research cables and power products.

SIGMA-X AES/EBU
Shunyata Research Sigma-X AES/EBU is a reference 110-ohm twinaxial digital cable with OCC copper conductors, a 100% foil shield, fluorocarbon dielectric, gold/copper-contact connectors, 35 TAPc elements, dual-element CMode filtering and four days of KPIP v2 processing.
WHO IS SIGMA-X AES/EBU 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 your components specify.
TECHNOLOGY
![]() | TAPc (Transverse Axial Polarizer) is Shunyata Research's patent-pending technology that couples to the electromagnetic fields around signal conductors. It works like a polarizer, passively reducing electromagnetic distortion. Sigma-X AES/EBU uses 35 TAPc elements. |
![]() | CMode is Shunyata Research's filter for common-mode noise, which is harder to measure and remove than differential noise. Shunyata designed it to reduce that noise without the compression effects of conventional filters. Sigma-X AES/EBU uses a dual-element CMode filter. |
![]() | KPIP v2™ is Shunyata Research's proprietary Kinetic Phase Inversion Process, applied to the conductor and terminal metals. Sigma-X AES/EBU receives four days of KPIP v2 processing, which Shunyata says greatly reduces burn-in time. |

FREQUENTLY ASKED QUESTIONS
Is this a 110-ohm cable?
Yes.
Does Sigma-X AES/EBU use PMZ?
No. Shunyata lists PMZ for its Sigma-X S/PDIF and clock models, not AES/EBU.
What is the standard length?
1.00 meter. We list lengths up to 3.5 meters.
