The TP-M920 features a selectable voice activation sensor and a one-touch recording button. The handy flashing indicator lets you know the unit is recording and the auto-pause saves valuable tape during conversation lulls. There are two selectable recording speeds -- the faster speed makes clearer recordings for reproduction, while the slower speed is perfect for voice memos and audio note taking. The built-in mic and speaker make it easy to record, cue, and review sounds and voice. This recorder features auto-stop at the tape's end and an earphone jack for incognito listening.
