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.

Solid Build

By Peter Hyatt

from Maine

Recorders have been improving for years now, and have since sought, within competition, to add lots of bells and whistles. Not so, for the Sony PCM D50. The D50 has its money invested in the quality of the recording. It is stunning. The quiet, marvelous reproduction amazes me. It is highly sensitive, so you will need accessories such as a wind screen and a tripod. The mini flexible tripod works well and can be held while holding the unit. It records in WAV and sending a WAV format recording to your computer is simple and fast. I tested this unit against the Zoom H4n (which I love) and found it to be superior quality. Perhaps my favorite thing about this recorder is the weight. It is heavy, and feels solidly made. I find the sound to be so stunning that I actually bring it, in a case, with me, just to listen to with headphones, like an ipod. It is not tiny so I put it on my desk while working. With high quality headphones, I have never heard better recordings. I have Dylan's "Tempest" on it, in WAV format (it can play MP3s) and it is amazing. You can do direct in line recording, or set up external microphones. I have not due to the high quality mics and preamps within the unit. I have found nothing better. Even when multi track recording, I record the basic track on this and then send it over to the computer or Tascam. It is that good.

Ease of use and quality are rare combinations


from Athens, AL

I recorded our church band during Easter and was very impressed with the high quality and balance in the recording. I had to place the mic in the center of the congregation on a tripod about 20 feet from the stage. Even with the close proximity, the recording was defined and had very nice balance. Our band consists of a Pearl electronic drum set, two electric guitars each through fender amps, keyboard and bass through on stage bass amp. One lead vocalist and three backing vocals. All instruments and vocals feed to a main board and PA. Acoustic environment is not the best as it is a former gym. Not ideal for recording, but it did a very nice job. I made a quick read of the first couple of pages of the owner's manual to cover what all the buttons do. Then read the quickstart and made a flawless recording. This is an expensive unit, but the recordings were worth the investment. Unit is larger than I thought it would be, but still is very compact. Descriptions that the unit is built like a tank are accurate. If it is within your budget, you will not be dissapointed with the unit.

never disappoints

By Joe Rodriguez

from Oakland, CA

With surprisingly awesome low end, and crystal clear highs, this recorder will not disappoint. I use it for foley, and for recording live sound. Great with the dead cat attachment, you can record band practice and shows clearly. The 5 second pre record has saved me many times. If you can afford it, and really need a field recorder, this is it. I wish sony made a rechargeable battery pack for it, AA's get expensive.
