2. SD Card Installation
The DR-100MKII uses SD or SDHC memory cards for recording. A 2GB SD card is included.
- Locate the SD card slot on the bottom of the unit.
- Gently push the SD card into the slot until it clicks into place. Ensure the card is inserted with the correct orientation.
- To remove, push the card in again until it springs out slightly, then pull it out.

3. Connecting Microphones and Line Inputs
The DR-100MKII offers versatile input options, including XLR/TRS combo jacks and a dedicated line input.
- XLR/TRS Inputs: Located on the bottom of the unit, these inputs support balanced XLR microphones (with +48V phantom power if needed) or 1/4-inch TRS line-level devices. The locking mechanism ensures secure connections.
- Line 2 Input: A 3.5mm stereo mini-jack input is available on the side for connecting external line-level devices.
- Digital Input: A dedicated digital input terminal allows for lossless connection from compatible digital audio sources.

4. Connecting Headphones and Line Output
- Headphone Output: Connect your headphones to the 3.5mm headphone jack on the side for monitoring audio.
- Line Output: A dedicated 3.5mm stereo mini-jack line output is available for connecting the DR-100MKII to external mixers, amplifiers, or other audio devices. This output is independent of the headphone output.
5. Powering On/Off
To power on the unit, slide the power switch located on the side. To power off, slide the switch to the OFF position.
Operating
1. Basic Recording
The DR-100MKII can record in WAV (linear PCM) or MP3 formats.
- Select Input Source: Use the INPUT switch to select between the built-in microphones (UNI MIC L/R, OMNI MIC L/R) or external inputs (XLR/LINE 1, LINE 2).
- Adjust Input Level: Use the large rotary input volume controls (L and R) on the top of the unit to set the recording level. Monitor the level meters on the LCD to avoid clipping.
- Press RECORD: Press the RECORD button to start recording. The button will illuminate.
- Stop Recording: Press the STOP button to end recording.

2. Advanced Recording Functions
- Auto Gain Control & Limiter: These functions automatically adjust the recording level to prevent distortion. Enable them via the switches on the back of the unit.
- Pre-record: Captures audio from 2 seconds before the RECORD button is pressed.
- Record Delay: Delays recording start slightly to avoid capturing button press noise.
- Low-Cut Filter: Reduces unwanted low-frequency noise (e.g., wind, rumble). Settings: OFF/40/80/120Hz.
- Overdubbing: Allows recording new audio over an existing file, creating a new file.
3. Playback
- Select File: Use the navigation buttons to select the desired audio file from the list.
- Press PLAY/PAUSE: Press the PLAY/PAUSE button to start playback.
- Adjust Playback Volume: Use the volume controls on the side of the unit.
- Repeat/Loop: Access these functions through the menu for continuous playback of a file or a specific section.
- VSA (Variable Speed Audition): Adjust playback speed without changing the pitch, useful for transcription or learning.
4. File Management
- Mark Function: Add marks at specific points in a recording for easy navigation.
- Track Increment: Automatically or manually split recordings into new files. Auto track increment can be based on file size or input level.
- Divide Function: Split a WAV file into two at a desired point.
- Quick Tag: Quickly tag files for identification.
5. Using the Remote Control (RC-10)
The included RC-10 remote control can be used wirelessly (infrared) or wired for precise operation, minimizing handling noise during recording.
- Wireless Operation: Point the remote at the DR-100MKII's IR receiver.
- Wired Operation: Connect the remote to the REMOTE/DIGITAL IN port on the side of the unit using the provided cable.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | Batteries are depleted or incorrectly inserted. | Replace or recharge batteries. Check polarity. |
| No sound during recording/playback. | Input/output levels too low; incorrect input source selected; headphone/line cables not connected properly. | Adjust input/output levels. Verify input source. Check cable connections. |
| Recording level is too low/high. | Input gain not set correctly. | Adjust the rotary input volume controls. Consider using Auto Gain or Limiter. |
| Cannot record to SD card. | SD card full, write-protected, or corrupted. | Delete unnecessary files, unlock the card, or format the card (will erase all data). |
| Remote control not working. | Remote batteries depleted; IR path blocked; wired connection loose. | Replace remote batteries. Ensure clear line of sight for IR. Check wired connection. |
