  Wiring 5 pin xlr phantom powered mic to 3 pin xlr

  Posted by Steve Dann on July 6, 2019 at 1:21 pm

  I need to connect a 5 pin xlr phantom powered mic. to a 3 pin xlr . I know the pinouts but I’m concerned about the phantom power. Can I link the hot and cold of both channels?. Will that affect the supply of + 48v to the mic or is it safer/simpler to just connect left or right? Any issues with that?

  Thanks in advance.

  You can probably do this. A much more confident response would be possible if we knew exactly which microphone you are asking about. Absent any details, it seems likely that applying phantom power to both channels would be safe.

  Recording audio without metering and monitoring is exactly like framing and focusing without looking at the viewfinder.

  Thanks Richard. The mic. is a short Sony gun mic. made specifically to fit on a professional Sony video camera. You can have the mic. output as stereo across ch. 3 & 4 or as mono to either or both chs 3 & 4. I’m going to break out the 5 pin socket to two 3 pin xlrs so I can record the camera mic to ch 4 and have ch. 3 free as another mic. Input. I’m keen to avoid blowing up anything by having +48v going to the wrong place, so hesitant to mono l & r from the mic. The mic is only used for natsot so maybe taking just one channel is the way to go. I’m aware that +48v will go to the other 3 pin xlr whether it needs it or not but that’s not been a problem in the past.
