Hey folks. First post here (although I've been reading anonymously for a little bit now). This may not be the best forum for this question, but figure I'll give it a shot.
I'm working on a video shoot that's kind of a mix of high level pro and entry/mid level equipment and expertise. We're shooting with an Arri Alexa, and recording audio to a Tascam DR-680 via a Sound Devices MixPre. Syncing to timecode is out of the question because of the DR-680, so we're wanting to send an audio scratch track to the Alexa in the form of an audio feed out of either the MixPre or 680 via a Sennheiser ew 100 G3 / SK 100 wireless transmitter located on the sound guy, to a corresponding EK 100 receiver on the Alexa, and into the Alexa's 5-pin XLR connection.
The question I have is regarding the 5-pin XLR cable into the Alexa. The output of the EK 100 is a 1/8" stereo, so I'm wondering about the best cable configuration to make this happen. I'm running only a signal shotgun mic, so don't need the 5-pin XLR's stereo capabilities, but DO need the 5-pin connection. I currently have a 1/8" to 3-pin XLR cable, which I obviously can't use alone.
One thought: use a 3-pin XLR female to 5-pin XLR male that would sit between the existing 1/8" to 3-pin XLR male cable I already have. Anyone know if this would be successful in sending signal to one of the channels?
Another thought (if the above doesn't work): use a 5-pin XLR male to a (2) 3-pin XLR female Y cable, plug in my existing 3-pin XLR male to one of them, and simply disregard the second XLR connector.
Hope that all makes sense.
Any thoughts? Again, I just need it for a scratch track so we can making syncing in post easier.
