AES on BNC
by audioeditor on Jan 14, 2008 at 7:53:20 pm
I searched here but didn't find an answer. I just ordered a Sony HVR-1500 and noticed it has AES output but on BNC rather than the more familiar XLR. Since a BNC is only two conductors, do you still get two channels on each BNC or is it back to one channel? And, how to you wire a cable from an AES stereo XLR to the BNC? I'm sure Sony did this to save space but it has thrown me a loop since I haven't dealt with AES on BNC before. Thanks for any help!

Does anyone know how to wire AES audio from an XLR (3 conductors) to a BNC (two conductors)? I can see two separate channels on an XLR (two hots with a common ground) but how to they accomplish 2-channels of AES into one BNC connector (only two conductors)? Do you use Belden 2-conductor shielded from the XLR and somehow go to Belden coax for the BNC? I'd appreciate a wiring schematic if someone has one.

Digital (AES) doesnt require pins 2 and 3 (hot and cold) to be present to provide stereo (ie 1 for left and 1 right). The stereo infromation is intrinsically encoded into the datastream.
Although Im not 100% on the wiring to go bnc to aes or vice versa, 2 mins with a soldering iron will tell you if my suspicion is corect.
