The PCM-D50 is a 96 kHz/24-bit recorder
Built-in Electret Condenser Microphones The PCM-D50's electret condenser microphones have exceptionally high sound quality and offer a selection of 2 operating positions, X-Y and Wide Stereo. X-Y covers a wide sound range with good depth, perspective and a natural sounding stereo image; or alternatively, a wide stereo position offering a wider spread stereo image.
Superior Audio Signal Path The PCM-D50 is designed with four separate circuit boards to separate analog audio, digital audio, digital recording, and power supply circuits. Separate circuit boards for each function helps minimize noise.
Simple Uploading to Computer The PCM-D50 conforms to the USB 2.0 Mass Storage Class Device standard and this recorder's native recording file format is .WAV. This means recordings can be rapidly uploaded to a computer and used in conjunction with most common audio production software.
Versatile Recording Functions The PCM-D50 offers comprehensive signal processing features for location recording including a unique dual digital limiter function (inherited from the PCM-D1 recorder), a high pass filter with selectable frequencies (150 Hz or 75 Hz) and SBM (Super Bit Mapping) noise shaping. In addition, the PCM-D50 includes a 5 second pre-record buffer with an A-B repeat playback function.
