Like its predecessors, the PMD670 is a rugged and reliable portable recorder specifically designed for applications like meeting recording, voice dictation, high quality sound gathering and everything in between. The PMD670 includes a built-in microphone, built-in speaker, and professional mic/line inputs and outputs. You can record many hours of quality stereo or mono audio on a single CF (compact flash) memory card or Microdrive. Transfer audio files into a computer for editing or distribution by simply placing a recorded card into your computer PC card drive or use the built in computer I/O port for a no hassle approach to file transfer. The PMD670 is also fully compatible with Marantz Professional's PMDEdit editing and file management software.
