Introduction Thank you for purchasing the Korg MR-1 1-bit mobile recorder. In order to take full advantage of your new equipment, please read this manual carefully and use the product as directed. When you've read the manual, keep it safe for future reference. Features The MR-1 is an ultra-high audio quality stereo portable recorder that can record and play back formats such as CD (16-bit/44.1 kHz), DVD audio (24-bit/192 kHz), and SACD (Super Audio CD) (1-bit/2.8 MHz).
Parts of the MR-1 Front and side panels 9 3 1 10 11 2 4 12 5 7 6 8 1. DC 5V connector Connect the included AC adaptor here (also used for charging the battery). 2. USB connector This lets you use a USB cable to connect the MR-1 to your computer. 3. Display The display shows the level meters and counter during recording and playback, and can also show information about the project (→p.13) or file, and parameter settings. 4. Playback/Pause button This button starts recording or playback.
9. Power button (with Hold function) This turns the power on/off (shutdown). By sliding this button to the HOLD position, you can prevent accidental operation from occurring when you inadvertently touch the buttons or the P-dial. 10. Menu button This button accesses the menu list (MENU) screen, allowing you to choose the information or parameters that will be displayed. Each time you press this, you will alternate between the level meter screen and the menu screen.
Screens and operations Level meter screen and menu list (MENU) screen When you power-on the MR-1, the display will show the level meter screen. When the display shows the level meter screen, pressing the menu button will show the menu list (MENU) screen which lets you proceed to various types of settings or informational screen. You'll use the P-dial from this screen to make various settings.
Basic operation 1. Power and usage The MR-1 contains a rechargeable battery that is convenient for mobile or outdoor use. If you're in a location where AC power is available, you can also use the MR-1 with the included AC adaptor. If the AC adaptor is connected, recharging will begin regardless of whether the power is on or off. Recharging will end automatically when the battery is full. Using the AC adaptor Plug the power cable of the included AC adaptor into an AC outlet.
Remaining battery indication The battery icon in the level meter screen indicates the approximate remaining battery capacity, and whether the battery is being recharged. If you continue playback or recording without using the AC adaptor even though the low battery indication is shown, the shutdown screen will appear automatically when the battery capacity is exhausted, and the power will turn off after several seconds.
2. Connecting your monitor equipment Connect stereo headphones to the headphone jack. Use the volume buttons to adjust the volume. If you're connecting the MR-1 to a monitor system, connect your stereo cable (mini) to the OUTPUT. Connecting headphones won't cut the sound from the output jacks. If you're recording from a mic, we recommend that you monitor through headphones to reduce the risk of acoustic feedback. 3.
4. Playing back the demo project The MR-1 contains a high-quality demo project that was recorded in DFF(DSDIFF) format. Here's how to play back this project. What is a project? When you record on the MR-1, two files are created; an audio file and a project file (containing protection data and markers, etc.). These two files are collectively called a "project," and can be operated on the MR-1 as if they were a single audio file. (→p.
5. The level meter screen When you turn on the power, the level meter screen is shown in the display. When the menu list (MENU) screen is shown, you can also access the level meter screen by pressing the menu button. This screen shows information such as the MR-1's operating status and recording/playback format.
6. Recording When you record on the MR-1, date and time information is automatically added to the file so that you can manage your projects more easily. If you set the date and time on the MR-1 (→p.28), the date and time will be correct. However, if the rechargeable battery does not have enough power to turn the MR-1 on and you let it sit for a few days, the date and time settings will be reset, so you'll need to set them correctly after recharging the battery.
Recording using the line inputs Set the input switch to LINE. If the level is too low even after you've adjusted the gain (→p.16), set the input switch to MIC. Selecting the recording format Here's how to select the recording format. Each time you record, a new project will be created in the recording format you've selected. The default setting is WAV 16-bit 44.1 kHz. 1. Press the menu button, and in the menu list, use the P-dial to select and confirm "REC MODE.
