Uncompromising, future-proof fidelity at an unprecedented price. Korg’s new, super-portable MR Professional Mobile Recorders break new ground by providing high fidelity 1-bit recording technology at unheard of low prices.

MR-1 Professional Mobile Recorder

The hand-held MR-1 provides high quality 1-bit/2.8 MHz recording and playback in a shirt-pocket portable package that is perfect for location recording, broadcast journalism, podcasting, live music performances – even for rehearsals and song-writing sessions.

By recording in 1-bit/2.8 MHz format you are assured that your most important, once-in-a-lifetime moments are captured in stunning detail, and ready for whatever the future brings you. And back in the studio it also provides superb final mix and archiving benefits.

Powerful new software bundled with the MR-1 recorder enables the conversion of your 1-bit recordings and mixes into all of today’s audio formats without degradation. Best of all, by archiving your data in 1-bit format you’re ready for the future, as playback systems and standards change.

Real world features
The MR-1 supports multiple recording formats including DSDIFF, DSF, and WSD 1-bit formats*, as well as multi-bit PCM format (BWF) with resolutions up to 24-bit/192 kHz.

It features a 20Gbyte internal hard drive, offering up to six hours of recording** at the highest audio quality (1-bit 2.8224 MHz stereo), or approximately twenty hours at CD quality (16-bit 44.1 kHz).

High-speed USB 2.0 connectivity provides for fast and easy transfer of files between the recorder and your computer. The MR-1 runs on AC or long-life rechargeable lithium polymer battery.

MR-1000 Professional Mobile Recorder

The MR-1000 is the perfect tool for the professional who wants to record and archive their final mixes in the studio, while its compact size and portability make it ideal for location recording, podcasting, live music performances – even for rehearsals and song-writing sessions.

After recording and editing all your tracks in the DAW/hardware system of your choice, you can mix directly, or via an analog summing mixer, to the MR-1000. This gives you the superb fidelity of high-rate 1-bit technology, which preserves all the transients, nuances, and “air” from the original recording.

Powerful new software bundled with the MR-1000 enables the conversion of your 1-bit recordings and mixes into all of today’s audio formats without degradation. Best of all, by archiving your data/mix in this new double-speed 1-bit format you’re ready for the future, as playback systems and standards change.

Real world features
The MR-1000 supports multiple recording formats including DSDIFF, DSF, and WSD 1-bit formats*, as well as multi-bit PCM format (BWF) with resolutions up to 24-bit/192 kHz.
It features a 40 Gbyte internal hard drive, offering up to six hours of recording at the highest audio quality (1-bit 5.6448 MHz stereo), or approximately sixty hours at CD quality (16-bit 44.1 kHz).
The table-top MR-1000 includes combination XLR/ 1/4" input connectors with top quality microphone preamps, phantom power and built-in limiting. Both XLR and RCA outputs are provided for maximum flexibility.

Designed for high audio quality
In order to deliver an unprecedented level of audio quality, careful attention was paid not only to the digital signal domain but also to the hardware design. The input/output circuitry of the MR-1000 features ultra-high quality mic preamps. Power is supplied independently to the MR-1000’s digital circuitry and analog circuitry, thus holding interference due to electrical current to an extremely low level. Every component of the MR-1000 has been carefully selected to maximize performance. The respected Cirrus Logic CS4398 is used as the DAC (Digital/Analog Converter), and the Burr-Brown PCM4202 from Texas Instruments is used as the ADC (Analog/Digital Converter). By paying close attention to every component, the design has minimized any possible degradation of the audio signal.

Quality and portability
The MR-1000 allows two-way operation; it can be powered by the included AC adaptor or by eight AA batteries, delivering 1-bit audio in a portable package that’s equally at home in the studio or in the field. It comes with a specially-made carrying case that lets you record without removing the MR-1000 from the case, making it a great choice for field recording. The large backlit LCD display guarantees excellent visibility, ensuring smooth workflow. The Almite-coated aluminum body provides strong impact resistance and stable operation in any situation.
1-bit technology equals pristine fidelity
1-bit recording is the latest advancement in audio, and has been adopted for use in the critically acclaimed SACD recording format. It offers a frequency response of DC to 100 kHz and dynamic range of 120 dB. This uncompromising fidelity, low noise floor, extended dynamic range, lifelike imaging and analog quality depth has been praised by top experts. But there are other important advantages to the format that are of benefit to all recording professionals, regardless of their tracking platform.

The Technology behind the new MR-1 and MR-1000 Mobile Recorders:

• 1-bit technology equals pristine fidelity - 1-bit recording is the latest advancement in audio, and has been adopted for use in the critically acclaimed SACD recording format. It offers a frequency response of DC to 100 kHz and dynamic range of 120 dB. This uncompromising fidelity, low noise floor, extended dynamic range, lifelike imaging and analog quality depth has been praised by top experts. But there are other important advantages to the format that are of benefit to all recording professionals, regardless of their tracking platform.
  
• Future proof flexibility - Today’s state-of-the-art 24-bit converters use high-speed 1-bit conversion to capture audio, using real-time decimation and other processes to present the data in the desired bit depth/sample rate format. The beauty of the MR’s bitstream format is that it uses the original 1-bit data, without the need for the other processes. What comes in comes out, with no manipulation needed.
  
  As files are converted and reconverted between various bit depths and sampling rates, there are possibly degrading effects, depending on the sample rate conversion algorithms. The critical issue is that files mixed and mastered in today’s state of the art resolution may be insufficient for tomorrow’s formats. Archiving your final mixes and masters in a 1-bit system allows you to bypass these issues, and preserve your music with both the highest fidelity and in a more "universal" format. That data then can more easily be converted at a later date to the bit depth/sample rate format of your choice without compromising the integrity or fidelity of the data. You can even convert to newer formats that will be adopted in the future, be they multi-bit or a further migration to the 1-bit format.
