recording communications
i recently got access to a sony digital camcorder, and am going to take it
up for a flight (passenger recording of course), and i wanted to patch in the intercom to its audio inputs. What is neccessary to adapt what comes out of the intercom to make it suitable for line level inputs to a camcorder? If anyone has made such a cable, or knows a place that sells them, i'd be interested in hearing from you. thanks. -casey |

I personally use a portable intercom with an audio out jack. -- John T http://tknowlogy.com/TknoFlyer http://www.pocketgear.com/products_s...veloperid=4415 ____________________ |

If you pull a few key words out of your post and Google the r.a.* archives, you'll find lotsa lotsa suggestions. |

Hi,
Plug a tiny microphone into your camcorder and stick it in the cup of your headset. Works amazingly well, cheap, no messing with wires/impedences etc, and you get both the intercom and ambient (engine etc) sounds. Hilton |

Yes, but you don't get what the pilot says over the radio or intercom. I have a Sony camcorder and you simply get a cord with a stereo minijack at either end if your camcorder is stereo, if it's mono get a mono plug on either end. You will need a mini to regular jack adapter for the airplane end. If someone will be sitting in the copilot seat then also get a Y adapter so the audio can go to both the passenger and the camera. |

Eh? Are you sure you don't hear yourself when you talk on the intercom or radio? My intercom has a sidetone that carries my voice quite nicely into the Radio Shack ceramic button mike that I have plugged into a digital voice recorder. The tiny mike is unnoticable when stuck into the headset cup. It could be plugged into the camcorder just as well as the voice recorder. |

I personally use a portable intercom with an audio out jack. John T John, I have a portable David Clark intercom with the audio out jack, but when I picked up a cable at Radio Shack and plugged it into my Sony camera (mic input) it didn't pickup any sound. The camera does however state (plug in power) just below the mic input but I'm not quite sure what that means. Any suggestions? David (KORL) |

The camera does however state (plug in power) just below the mic input but I'm not quite sure what that means. I don't use DC headsets, but I can think of a couple things to check. First, are the DCs stereo? That *may* affect the audio out jack, but I wouldn't count on it. Also, make sure the volume is turned up on the headset (kinda hard to miss that one if you're wearing them . Second, make sure the audio cable is plugged in to the red mic/power jack on your Sony. My model has a green headphone jack and a red mic/power jack as you described. -- John T http://tknowlogy.com/TknoFlyer http://www.pocketgear.com/products_s...veloperid=4415 ____________________ |

Hi,
Excellent results are achieved by buying a tiny microphone, plugging it into the camera, and placing it in your headset's ear cup. You get the intercom and ambient sound in a good ratio. It works great, is fool/failure-proof and doesn't have you messing with impedences etc etc etc. Hilton |

I had excellent results by making a cable with a small jack for the camcorder at one end, and a large jack that plugged into the intercom at the other. Concealed within the large jack was a 47K ohm (IIRC) variable resistor. It turned out it needed all 47K ohms to get the levels right. I'm sure there is more correct ways of impedance matching, but analogue electronics is not my thing :-) I built the cable by buying a mono-to-stereo cable at Radio Shack and chopping off the mono end and putting my custom jack on that end. -- Dylan Smith, Castletown, Isle of Man Flying: http://www.dylansmith.net Frontier Elite Universe: http://www.alioth.net "Maintain thine airspeed, lest the ground come up and smite thee" |
