The latest addition to Sony's family of portable audio recorders, the PCM-D50 recorder adopts many of its features and style from the highly acclaimed PCM-D1 model, including rugged construction and cool design. It's the ideal choice for making live musical, wild tracks and field recordings.

The PCM-D50 is a 96kHz/24-bit recorder fitted with two-position (X-Y or Wide) stereo microphones, 4GB of internal fl ash memory and a Memory Stick Pro-HG Duo™ slot for additional storage. Operating on four AA alkaline batteries, it provides 14 hours of record operation at 44.1kHz 16-bit recording. Unique features such as a two-position stereo microphone, a pre-record buffer that records fi ve seconds of audio before hitting the record button, digital pitch control and A/B segment/repeat offer great portable possibilities for songwriters, musicians and journalists.

To complement the PCM-D50 recorder, new optional accessories include a remote control, tripod stand and microphone windscreen.


Superb Recording Quality

The PCM-D50 is a 96kHz/24-bit linear recorder that records in standard .WAV file format and surpasses standard DAT sound quality. A low signal-to-noise ratio provides virtually noise-free recording quality.

Expandable Memory

With a 4GB built-in memory, the PCM-D50 records up to six hours when recording in 44.1kHz 16-bit CD quality mode. The Memory Stick Pro-HG Duo Slot provides up to 4GB memory expandability.

Built-in Microphones

The PCM-D50 recorder comes equipped with a high sensitivity, built-in, two-position electret condenser stereo microphone with flexible rotation for either X-Y or Wide stereo positions.

Versatile Recording Functions

The Dual Digital Limiter feature helps prevent distortion, a pre-record buffer records five seconds of audio before hitting the record button and Super Bit Mapping technology helps achieve wide, dynamic range.

Playback Functions

The PCM-D50 recorder provides MP3 playback, a special Digital Pitch Control feature that slows down playback without changing pitch and an A/B segment/repeat feature that allows you to mark and repeat segments.

PC/Macintosh Compatible

The PCM-D50 utilises a simple drag and drop file transfer via a high-speed USB connection.

Rugged Construction

Constructed of lightweight metal (aluminium), the PCM-D50 recorder is built to withstand the demands of professional applications.
