DIGITAL AUDIO CABLES
DIGITAL AUDIO CABLES
Low-loss, low-jitter, precision impedance coax for Word
Clock, AES3id, SPDIF, or multiplexed digital audio for-
mats. The same as Gepco's HD video series, these
coaxial cables utilize Gepco's 4.5GHz gas-injected,
low k constant dielectric and a precision-drawn,
solid copper conductor. For comprehensive
broadband shielding, a dual shield, foil and
braid, is used to protect against both high-
frequency RF and EMI noise and interfer-
ence. All electrical and mechanical char-
acteristics are manufactured to precision
tolerances and specifications to mini-
mize attenuation, internal reflections,
and impedance mismatches. As a
result, pulse rounding, bit-errors, and
jitter from the cable interconnection
are minimized.
