8mm to video sound problems

[rollemfilm]

my guess is the camera uses phantom power
for it's mic. you'll need to get a converter.

I'm transferring some 8mm sound movies to video using an Ambico Transfer System, an ELMO ST-180e and a Sony Digital Video Camera. I adjusted the speed of the ELMO and eliminated the flicker in the video but I'm getting a severe hum on the audio. I'm connecting the audio out on the projector to the mic input on the camera. Any suggestions?

This is not something I know a great deal about, because I shoot silent--
But my guess is that you are feeding a line-level output into a mic-level input, which will give you very bad audio. Radio Shack sells a small red plug which converts from RCA-line to 1/8"-mic level. You could look for this, or try to rig up something which would reduce the volume level going in to your camera.

you need 3 resistors: 47 kOhm, 1 MOhm, 1 kOhm.
connect the 47 kOhm in parallel to the projector?s output,
connect the ground of the projector to the ground of the mic jack (shield of the cable)
connect the 1 kOhm resistor in parallel to the mic input
connect the 1 MOhm resistor between the projector?s output and the mic input.

If the sound now is to silent, you can experiment substituting the 1 MOhm resistor with 100 kOhm, to make the level 10 times higher.

If the hum remains, you need a sound transformer, as used in car audio to connect radios to external amps. This transformer separates the ground of projector and camera, to avoid any loop. connect the transformer to the projector and the resistors between transformer and camera.
