Olympus Outs DM-620 PCM Recorder

Believe it or not, handheld mics are a blogger’s best friend — I use the Zoom H1 almost daily. The DM-620 PCM is no different. The handheld mic records uncompressed 16 bit/48 kHz Linear PCM audio and stores it on the 4GB built-in memory (up to 32GB with microSD/SDHC Card). Features like auto-leveling, scene select, noise cancelation, zoom microphone and low-cut filter help identify recording conditions and adjust accordingly.

It looks like a pretty much standard mic for the most part. But it will win major points if it feels nice and sturdy — the H1 feels really cheap.

Price is $149.99, available in mid-March.

Intuitive DM-620 Digital Recorder Employs Three Mics To Capture Lower Bass Audio And Deliver Amazing Clarity To Speech, Music Or Ambient Sounds

CENTER VALLEY, Pa., March 2, 2011 –Olympus, the market leader for portable digital voice recorders and professional dictation devices, builds on its reputation for incredible audio engineering with the introduction of the new DM-620 PCM audio recording device featuring a three microphone TRESMIC system designed to capture low frequency sound for premium recordings. The device also offers cutting-edge technology options like voice guidance for users with assistive needs as well as auto-leveling, scene select, noise cancelation, zoom microphone and low-cut filter for capturing ideal recordings regardless of the environment. All of these features and more are packed into a compact, lightweight, sleek metal body with uncompressed 16 bit/48 kHz Linear PCM recording format enabling you to capture it all.

“The Olympus DM-620 is an intuitive PCM recorder made to capture pristine audio regardless of environmental sounds,” said Amy Leslie, product manager, Olympus Imaging America Inc. “For any profession – businessperson, lawyer, journalist, teacher or college student – the DM-620 is an easy-to-use device for anyone looking to capture clear, quality audio recordings.

Don’t Miss A Thing
The DM-620’s TRESMIC system employs two condenser stereo mics and a center, omni-directional mic capable of capturing lower bass ranges down to 20Hz. Sensitive microphones are of utmost importance to capture the nuances of every note, word or sound regardless of frequency. Combined with more than 1,000 hours of consecutive recording capacity, the DM-620 doesn’t miss a beat.

No Limitations
A key feature of the DM-620 is complete voice guidance functionality: the recorder can provide audio prompts for users with assistive needs. This optional function helps the user operate the device without the need to see the menus or buttons. Languages can be set to English, French, Spanish and Portuguese. Those with visual or learning disabilities have long been faithful Olympus users, and the DM-620, like its DM-series predecessors, was built with assistive needs in mind.

Perfect Audio for Any Situation
Settings like crowded press conferences, jam-packed courthouses and large lecture halls can produce unwanted background noise that may compromise an audio recording. The DM-620 combats unwanted environmental sound with a litany of menu options like scene select, noise cancellation, zoom microphone and low-cut filter.

Scene Select mode helps optimize recording quality with preset environmental settings that correspond to common surrounding conditions. The Noise Cancellation feature blocks out unnecessary background noises that can sometimes overwhelm a recording. Set to high, medium or low frequency, the zoom microphone function allows users to focus on capturing sound from a particular audio source. In addition, a switchable Low-Cut Filter eliminates low-frequency sound from 100Hz or 300Hz. Background noises like whispers or coughing in a lecture hall can be greatly minimized with these options.

Get More For Less
Equipped generously with 4-gigabytes of internal flash memory, the DM-620 easily captures lengthy, uncompressed PCM recordings or MP3 and WMA recordings. It also features a microSD/SDHC removable media card slot for up to 32 gigabytes of additional data. Users can effortlessly move files between internal and external memory to help manage storage.

Uncompressed 16 bit/48 kHz linear PCM recording capability captures rich, dynamic sound quality and the DM-620 has the versatility to record and play back in PCM (WAV), MP3 and WMA formats with either its internal mics or by plugging in an external mic. Ideal for extended meetings, classes or interviews, the DM-620 operates on two rechargeable AAA batteries.

Transfer. Edit. Enjoy.
Olympus Sonority® Software is included with the DM-620 to simplify the managing and editing of audio recordings. It allows users to easily download, manage and convert sound files and perform waveform editing on a PC or Mac. Downloading large audio files onto a computer is a cinch: the DM-620 is a USB Mass Storage Class device with USB 2.0 high-speed transfer capability. The device will even automatically recharge its batteries while it’s plugged into a USB outlet.

Record How You Want To
The DM-620 allows the user to choose between two options for setting the recording levels – Auto and Manual. Both are set in the device’s menu screen. In the Auto setting, the recorder automatically establishes the recording level in conjunction with the microphone sensitivity. If a sudden volume spike occurs, the DM-620 compensates the sound level to prevent distortion. In the Manual option, the sound level is set through commands on the menu screen. The user has the option of applying a limiter when using the manual option, which compensates when a spike in signal occurs – much like the auto setting does automatically.

Sleek Olympus Look and Feel
The DM-620 features a lightweight, aluminum body with three mics, function buttons and generous LCD screen. At just 4.4 inches long and 3 ounces in weight, the DM-620 provides remarkable power that fits in the palm of a hand.

An easy-to-read, 1.69-inch backlit LCD screen shows file information, recording time and events clearly. A user-friendly thumb pad provides control to adjust volume level, and fast-forward and rewind with a simple touch. Stop and record buttons are located above the thumb pad and erase and file List buttons are positioned below for easy access.

No Strings Attached with Wireless Remote
An optional RS-30W Wireless Remote empowers users to start and stop the recording of the DM-620 without touching the unit. This remote is ideal for large conferences or classrooms, as the device can be placed in an optimal recording position and activated at a distance.

In addition to Olympus Sonority software, the DM-620 is packaged with a USB cable, carrying case, two rechargeable AAA batteries, strap, instruction manual and Olympus warranty card. Optional accessories for the DM-620 include the infrared RS-30W Wireless Remote, A-514 AC adaptor and TP-7 Telephone Pick-Up.

Pricing and Availability
The DM-620 provides excellent audio recording at a highly competitive price for a Linear PCM recorder: an estimated street price of $149.99 (U.S.). It will be available in mid-March 2011. To purchase online, visitwww.getolympus.com.
