The Pearlcorder J300 microcassette recorder is compact, stylish, and loaded with features. And it's smaller and more ergonomic than any other Olympus microcassette product, meaning it's easy to carry around. An actuator begins recording at the sound of a voice and stops when the voice does. Fast-play mode lets you listen 25 percent faster than normal speed. And the dual tape-speed function can record three hours of voice on one 90-minute microcassette tape. Also included is a tape counter for easy location of previously recorded passages.
