Audio return / tape playback / standby voltage
Notes for pinouts sets:
N1. A 1970s B&W Panasonic WV-85, and many others, used this wiring. Although there's plenty of other variations.
N1.-N4.: The microphone is usually amplified, but still at the usual microphone levels. VTR playback re-uses pin 1, with a few volts DC on top (as a mode switching signal).
This pinout, with option N1 works for the Canon VS-30. The pinouts are for the MALE end of the cable that is permanently installed in the camcorder.
Note for CCJ cable: All shields are isolated from each other, other than the two that join on pin 4. There may be a shield around all the wiring in the cable, this may be joined to the pin 9 ground.
Some device-specific pinouts:
Two 24 volt tally lamps are directly wired across pins 6 & 10, the top and rear tally lamps, in parallel. The intercom line is wired directly to the tip and ring of the ¼ inch TRS jack, with a 3 volt (if I recall correctly) baristor from tip to sleeve. The intercom is totally isolated from the rest of the camera, ground, and the chassis. The intercom headset has a 35Ω carbon mike between tip and sleeve, and a 160Ω earpiece between ring and sleeve. The camera is separately mains powered.
Directly usable with the NV-100 portapak VCR.
If video is present on pin 1, record/pause control is from the camera. Otherwise, the pause button on the VTR is used.
