I am thinking of replacing the camera end of my hirose umbilical with a 10 pin XLR or possibly a 7pin XLR as they are more readily available here.
I'm using a Nomad but I found a pin-out for the hirose 10-pn on the Sound Devices site (this is for their panel mount 10pin in the 552)
1 – L (+) output
2 – L (–) output
3–R(+)output
4–R(–)output
5–R(+)returnA
6–n/c
7–L(+)returnA
8 – n/c
9 – ground
10 – ground
Question: Is that second ground really necessary. I not I could use a 7 pin XLR to carry 2 balanced XLR, a stereo return and a ground.
I assume it is necessary as there are some unconnected pins, but if anyone could confirm, and/or explain why, that would be great.
Many Thanks,
B
