Studio Recorder

Un-beatable Audio Performance Comes Home to Roost - Meet the Korg MR-2000S!
Korg captured the world's attention with their MR series of DSD mobile recorders and studio tools. After consulting with top recording and mastering professionals, Korg has now created the Korg MR-2000S Studio Recorder; a 2-track mixdown designed from the ground up to bring that same DSD sonic performance home for use in any studio environment.

A DSD and Mastering Recorder Born to Run
In keeping with the MR Series studio recorder heritage of portability, the MR-2000S 1- bit recorder adds a number of new features to meet the requirements of the most demanding studio, yet retains a sleek, single rack-space profile. This compact format is also ideal for any live recording rig; or for grabbing that "off-the-board" live recording night after night - as well as shuttling your recordings from venue to studio and back again. So whether you want to capture that once-in-a-lifetime performance with impeccable detail, or need to transfer those priceless recordings from session to session, the MR-2000S high-resolution audio recorder is ready to roll.

Master. Class.
All of Korg’s MR Series recorders feature the 1-Bit/2.8224 MHz format used in creating the SACD (Super Audio Compact Disc). The MR-2000S goes above and beyond this industry standard to provide 1-Bit/5.6448 MHz recording. At such accelerated sampling rates, the entire sound stage is faithfully captured, even during the softest passages. The clarity, ambience and true dynamic range of the original sound source are preserved with unprecedented accuracy.

By mastering in this superior format, the recorded material can always be re-created natively in whatever format you require, providing a true future-proof archive. In supporting these recording requirements, the MR-2000S uses the highest-quality components available - the CS4398 Digital to Analog Converter from Cirrus Logic and the Burr-Brown PCM4202 Analog to Digital Converter from Texas Instruments Corporation - minimizing any possible degradation of the audio signal.

Format Fiesta
In addition to the aforementioned 2.8 MHz and 5.6 MHz 1-Bit formats (DSDIFF, WSD and DSF formats are supported), the MR2000S is ready to record in any of the current 16-Bit and 24-Bit formats (from 44.1 kHz up to 192 kHz) directly, in BWF (Broadcast WAV) format.

Easy on the Ears, Easy on the Eyes
Sure, the fidelity of the MR-2000S is a feast for the ears. But the multi-stage LED metering is a treat for the eyes as well. Accurate and responsive, each channel employs 24 bright, color-coded LEDs to provide detailed level information that is highly visible from nearly any vantage point, whether in the studio or in a remote live capture environment.

Got the Hook-up?
Versatility is the key when creating a recorder with a wide range of applications, and that’s where the MR-2000S shines. The XLR analog inputs feature a selectable -12dB, -14dB -16 dB, -18dB or -20 dB reference level, insuring the proper level match with nearly any audio source. XLR analog outputs are also provided. In addition, the MR-2000S is equipped with analog RCA style inputs and outputs for maximum flexibility.

On the digital side, coaxial S/P DIF digital I/O provides smooth integration into any 16-Bit or 24-Bit digital studio environment – from the music workshop to the broadcast studio. The MR-2000S also provides word clock I/O for reliable digital synchronization between various digital audio equipment or even between two MR-2000S Studio Recorders.

Save it for Later
The MR-2000S delivers up a whopping stereo record time of nearly 120 hours (16-Bit/44.1 kHz). Even at the highest resolution (1-Bit/5.6 MHz), the 80 GB internal hard drive provides a generous 14 hours of stereo recording time. In fact, the entire file structure of the MR-2000S has been designed to provide ample versatility and ease of use. 

When you begin recording, the MR-2000S creates a date folder for that day (just as digital cameras can date each picture). Up to 400 “Date” folders can be created on the hard drive, and each can contain up to 400 “Projects”. Each MR-2000S recording creates two types of files: one containing the audio data and a second containing any marker data or protect settings. Collectively, these two files are called a “Project”, and the MR-2000S handles them as a single audio file.

To keep the internal drive ready and available, a convenient hi-speed USB 2.0 port allows files to be quickly saved and stored via PC. In fact the MR2000S’ internal hard drive can be used as a FAT32 USB external drive to carry source material and other files when needed.

Going for the One
It has never been easier to add the benefits of 1-Bit recording and future-proof archiving to your musical or commercial recording world, thanks to the new MR-2000S Studio Recorder. But don’t let that name fool you. The one-rackspace MR-2000S is also a welcome addition to any live sound/recording rig, for bringing home that rare performance in legendary 1-Bit clarity.
