Olympus LS-P1 Portable Handheld Digital Audio Recorder (4GB, Silver)


The silver 4GB Olympus LS-P1 is a portable handheld digital audio recorder intended for capturing interviews, speeches, music, and sound effects in compressed, standard, or high-resolution formats. It features selectable recording modes, noise cancellation, an 18mm dynamic speaker, and a 3.5mm headphone output. Use the built-in low-noise stereo microphones or connect an external mic to the 3.5mm mini-jack input. Record to the 4GB internal memory or your own microSD cards in uncompressed linear PCM format at up to 24-bit / 96 kHz resolution or in compressed MP3 format at up to 320 kb/s resolution.

The backlit 1.43" LCD display enables clear viewing of menus and selections, which are easily changed via the navigation buttons. The lightweight metal-bodied LS-P1 is powered by the included AAA NiMH battery and can be recharged via connection of its retractable USB 2.0 jack to a computer or an AC adapter (available separately).

  • Built-in, low-noise microphones feature 90° orientation for an optimized stereo field
  • Advanced amplifier circuit suppresses interference while an Olympus-developed codec reduces noise during AD/DA music conversion
  • Record in PCM (WAV) format at up to 24-bit / 96 kHz or in MP3 format at up to 320 kb/s
  • Direct USB connectivity for easy data storage and transfer
  • Manually or automatically set your recording level and activate the integrated limiter function to ensure distortion-free audio capture
  • Selectable low-cut filter reduces low-frequency hum and rumble
  • Dedicated calendar button allows quick access to audio files, which are automatically marked with the date and displayed in the calendar format
  • Includes a tripod adapter for easy attachment to your preferred tripod stand
  • Selectable voice balancer cuts high- and low-frequency components and compensates low-volume portions during playback
  • Noise cancellation reduces ambient noise
  • Directional quality control technologies narrow the pickup angle of the microphone to increase the recording level and focus on the intended sound source in noisy environments
