Sony PCM-D50

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 metal (aluminum) and it’s 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/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. Additionally, the D50 offers compadible mounting and use with the recently introduced XLR-1 wide-bandwidth balanced XLR microphone adapter.

Highlights:
Portable and rugged 96 kHz and 24 bit recorder
LCD digital peak bargraph metering – along with dedicated nominal and peak level LED’s
Offers solid-state storage – free of drive mechanisms
Built-in high quality electret condenser stereo microphones
Dual A/D digital limiter and low cut filter
MP3 playback and digital pitch control

Features:
Built-in Electret Condenser Microphones

The PCM-D50’s electret condenser microphones have exceptional 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 wde 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.
