Thank you for viewing. It works without any problems. Built-in microphone: Omnidirectional, stereo Sampling frequency: 44.1kHz/48kHz/96kHz (WAV) Quantization bit depth: 16bit/24bit Power supply: 2 x AA batteries (alkaline or Ni-MH) External dimensions: 61(W) x 141(H) x 26(D) mm Weight: 164g (including batteries) / 116g (without batteries) High-quality stereo recording is required in many situations, such as music practice, concerts, as well as recording wild birds, train sounds, and, more recently, audio for videos. The TASCAM linear PCM recorder series, which houses a microphone unit with excellent responsiveness in a compact body, meets the demand for high-quality recording in these situations.
