Through impedance matching, low attenua-
tion, bandwidth certification, and noise rejec-
tion, cable induced bit-errors and jitter are
eliminated or minimized.

S or 75S Impedance

Digital audio cables feature a 110

S or 75S

characteristic impedance. Impedance matching
ensures low attenuation and minimal signal
reflection which can result in bit-errors or jitter. 

All 110

S digital audio cables are certified to

25MHz for transmission of sample rates up to
192kHz. The bandwidth ensures that the loss,
impedance, and return loss meet or exceed the
relevant standards across this range.

Digital audio data transmission requires a 110

S impedance

and up to 25MHz of bandwidth. To achieve the bandwidth
and impedance requirements, all digital audio cables utilize a
low k constant nitrogen/polymer dielectric.

Cable conductors are made from stranded tinned-copper,
99.999% oxygen-free copper, or precision-drawn solid cop-
per.  These conductor types provide maximum conductivity for
high frequency data signal transmission.

Each cable has time-saving features such as color coded jack-
ets, optimized conductor stranding, drain wires, and easy-to-
strip compounds.

The characteristic impedance of cable is determined by the
physical relationship between the conductors and shield. To
stabilize the impedance, every 110

S twisted-pair cable fea-

tures a nonconductive polymer rod that maintains the geom-
etry, and thereby impedance, of the cable core.

In addition to the pair twisting, noise rejection in balanced
cables is achieved with a 100% aluminum/mylar shield or a
tight-angled braid shield. Aluminum/mylar foil provides addi-
tional strength compared to standard foil shields, while a
tight-angled braid achieves greater strength, flaccidity, and
coverage.

All digital audio cables meet or exceed AES3 or AES3id stan-
dards for digital audio transmission.
