ABSTRACT:
A small AM/FM audio player, operating as a radio, tape, cassette or disc machine can be adjusted to receive music or other audio programs. The received programs can be heard audibly through a stereo Y-adapter set of earphones, and also through a set (pair) of stereo microphones which are clamped by spring loading on to a stereo microphone of a camcorder. The small AM/FM audio player can be programmed to emit any desired program and can be audited by personnel simultaneously with recording the audio program. Thus the picture being shown by the camcorder can be concurrently coordinated with the audio messages inexpensively.
