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.
Features:
- 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
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.
