Topic: FYI - AES Cables - 110 Ohms

[sickrick43]

Just an FYI...

Plain old microphone cables will work also, but...

AES (XLR Style) cables are supposed to be made from 110 Ohm cable.  This is documented on the back of Hosa packaging "On the Coaxial side, use high-quality 110-Ohm XLR-terminated cable, like Hosa's AES-Series".

From the Canare site: "Digital audio signals are transmitted at high, video-like frequencies (@ 6MHz) and should be handled very differently than standard analog audio lines. Commonly used XLR-3 microphone cables have various impedance ratings (30 ohm to 90 ohm typical) and exhibit poor digital transmission performance. The result is signal drop out and reduced cable lengths due to severe impedance mis-matching (VSWR) between AES/EBU 110 ohm equipment."

With all the people here using JB3's with converters, just thought I'd pass this along.  This could be the cause of many signal-quality type issues that people here are experienceing.

I was getting ready to make a short AES cable from some spare Star-Quad, when a friend made me aware of this. (yes, I don't know everything)

glad ive been rockin a kindkables cable, made from canare 110ohm, and black neutriks!!!

havent had ANY problems yet

yeah, i have some of the canare 110Ω cable left over for the diyer's out there.
