This interface requires balanced connections using high-quality, low-capaci-
tance, controlled-impedance, data communication, twisted-shielded pair cable.
Microphone cable may introduce a significant amount of jitter into the
signal, causing distortion.
Use commercially-available, consumer audio optical cable assemblies.
This interface is unbalanced but, because it carries digital signals, it requires the
use of 75 RG-59 coaxial cable.
Below are recommended cable and cable assemblies. Similar cables from
sources other than those listed here may be appropriate.
