I have the PS Engineering PM 1000 II, the specs say the headphone
impedance range is 150-1000 ohms. Craig Prouse wrote: Newps wrote: wrote: I don't know of an off-the-shelf adapter, but it needs to be an impedance adapter. Headsets are typically 150-300 Ohm, with voltages running upwards of 10V. Portable devices like cd players and other line-in critters use a much lower voltage, and expect a lower source impedance. If you truly want to go into the mic port, it'd have to accept and modulate the bias voltage coming from the video-cam as well, I'd expect. If it were me, I'd build one... but need to do more research first. If you have a Sony with a mic in a simple cord from Radio Shack will suffice. Unless you have an intercom that can't drive an 8 ohm load, in which case you'll get nothing on the tape and nothing in your headset. Or a fire in your intercom. Your intercom sees that Radio Shack cord as almost a short circuit. |
