Product Features

• Two-channel portable handheld audio recorder with microSDXC card storage
• 32-bit float resolution ensures low-noise, distortion-free recordings
• Built-in condenser microphones handle loud environments and sources (up to 125 dB SPL)
• 2-in/2-out USB-C audio interface for recording directly to your computer
• More than 17 hours operation with two AA alkaline batteries
• Supported audio formats:
• Linear PCM (WAV/BWF) at 32-bit float, 24 bit, 16 bit (sampling rates 96 kHz, 48 kHz, 44.1 kHz)
• Compressed (MP3): 32–320 kbit/s at 44.1/48 kHz (VBR files can be played but not recorded)
• Recording
  • Cardioid stereo condenser microphones, easy to set up in either AB or XY configuration
  • XY configuration allows mono compatible recordings and high sound localization acuity (lively interviews or field recordings with ambience)

  • Manual recording level setting for music and field recording
  • Three options of automatic level control during recording: Peak Reduction, Auto Level, Limiter
  • Auto-recording function to automatically start recording based on input level
  • Marks can be added automatically when using the automatic recording function
  • Overwrite function for punch-in recording with one level of Undo
  • Overdub function for non-destructive overdubbing
  • Dictation mode designed for human voice recording and transcription
  • Pre-recording buffer (2 seconds) allows a recording to start before the record key is pressed
  • Self-timer allows a recording to start 5 or 10 seconds after pressing the RECORD button
  • A new file can be created manually during recording or automatically when a certain file size is reached
  • Set marks to quickly locate certain audio positions (up to 99 per file)
  • Automatic tone generator convenient when editing with video on other equipment
  • Stereo mic/line input with plug-in power to connect an external source or microphone
  • File name format can be set to use a predefined word or the date
• Playback
  • Automatic level align prevents uneven playback levels
  • Variable speed audition to change the playback tempo without affecting the key (50–200 %)
  • Repeat/loop function (repeat one track, all tracks or a marked section, convenient for practicing music and studying languages
  • Playlist feature to play files in a certain order
  • Resume function retains the last stop position and starts playback from that position when power is turned back on
