Sony PCM-D50 Portable Linear PCM Digital Recorder
The PCM-D50 is a 96 kHz/24-bit recorder fitted with
two-position (X-Y or Wide) stereo microphones, 4 GB of internal flash memory,
and a Memory Stick Pro-HG Duo slot for additional storage. The body of the D50
is constructed of lightweight aluminum and it is built rugged to withstand the
demands of pro applications, plus it offers long battery life using conventional
AA alkaline batteries. The recorder includes a USB high-speed port for simple
uploading/downloading its native .WAV format files to and from Windows PC or
Macintosh computers. Other unique PCM-D50 features include digital pitch
control, dual digital limiter (inherited from the PCM-D1), low-cut filter, Super
Bit Mapping, A-B repeat, and MP3 playback capability. To complement the D50
recorder, new optional accessories include a remote commander, tripod stand, and
microphone windscreen.
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.
