2. Setup

2.1 Unpacking and Initial Inspection

Carefully remove the RD-8 from its packaging. Inspect the unit for any signs of damage during transit. Retain the packaging for future transport or storage.

2.2 Power Connection

Connect the provided power adapter to the DC input on the rear panel of the RD-8. Plug the adapter into a suitable power outlet. The unit operates on DC power.

2.3 Audio Connections

The RD-8 offers flexible audio output options:

• Main Mix Output: Connect a standard 1/4" TRS cable from the main mix output to your mixer or audio interface for a summed mono output.
• Individual Outputs: Each drum sound has its own dedicated 1/4" mono audio output. Connecting a cable to an individual output removes that instrument from the main mix, allowing for separate processing and mixing.
• Headphones: Connect headphones to the dedicated headphone jack for monitoring.

2.4 MIDI and USB Connections

The RD-8 can be integrated into your studio setup via MIDI or USB:

• MIDI In/Out/Thru: Use standard 5-pin MIDI cables to connect the RD-8 to other MIDI devices for synchronization and control.
• USB: Connect the RD-8 to your computer via a USB cable for MIDI over USB functionality, firmware updates, and data transfer.

2.5 Firmware Update

It is recommended to check for and install the latest firmware update for your RD-8 to ensure access to all available features and performance enhancements. Firmware updates are typically performed via a computer connected through USB. Refer to the official Behringer support website for detailed instructions and the latest firmware files.

3. Operating the RD-8

3.1 Basic Controls and Interface

The RD-8 features a comprehensive layout of knobs, buttons, and a display for intuitive control over its functions. Familiarize yourself with the following key areas:

• Master Section: Includes master volume, headphone volume, and global FX controls (Cutoff, Resonance, HPF On/Off).
• Instrument Sections: Each of the 16 drum sounds has dedicated controls for Level, Tuning, Tone, Decay, and Snappy, allowing for detailed sound shaping.
• Mode Section: Buttons for selecting Song, Pattern, and Step modes.
• Sync Section: Controls for internal, MIDI, and USB clock synchronization.
• Sequencer Controls: Includes Tempo, Swing, Prob (Probability), Flam, and various step/note repeat functions.
• Step Buttons: 16 illuminated step buttons for pattern programming and selection.

3.2 Programming Patterns

The RD-8's 64-step sequencer allows for complex rhythm creation:

1. Select Pattern Mode: Press the PATTERN button.
2. Choose a Pattern: Use the step buttons (1-16) to select an empty or existing pattern slot.
3. Select Instrument: Press the SELECT button for the desired drum instrument (e.g., Bass Drum, Snare Drum).
4. Enter Steps: Use the 16 step buttons to program the rhythm. An illuminated button indicates an active step.
5. Accent: The ACCENT function can be programmed like a drum track. It does not produce sound itself but increases the volume and thickness of other drum sounds on that specific beat. This can also be sent as a CV trigger.
6. Polymetry: The sequencer supports polymetry, allowing different track lengths for creative rhythmic variations.
7. Step Repeat & Note Repeat: Utilize these functions to add dynamic variations and fills to your patterns.
8. Real-time Triggering: Drum sounds can be triggered in real-time for live performance and recording.
9. Track Mute & Solo: Use the MUTE and SOLO buttons to isolate or silence individual drum tracks during playback.

3.3 Integrated FX Track

The RD-8 includes an integrated FX track with a Wave Designer and a dual-mode analog filter:

• Wave Designer: Adjust the Attack and Sustain parameters to shape the transients and decay of selected drum sounds.
• Analog Filter: A dual-mode analog filter (HPF/LPF) can be assigned to specific voices, allowing for creative frequency sculpting. Controls for Cutoff and Resonance are available.
• Automation: Live recording, editing, and playback of analog filter cutoff movements can be automated, adding dynamic expression to your patterns.

3.4 Song and Pattern Management

The RD-8 allows for extensive organization of your musical ideas:

• Storage: Store up to 16 songs and 256 patterns internally.
• Import/Export: Patterns and songs can be imported or exported during playback, enabling an unlimited number of compositions.
• Pattern Mode: Organize individual patterns into complete songs, defining the number of repetitions for each song part.
• Song Mode: Chain multiple songs together for extended live sets or complex arrangements.

3.5 Auto-Scroll Function

The unique auto-scroll function facilitates improvisation across all modes, allowing for fluid exploration of rhythmic ideas.

4. Maintenance

4.1 Cleaning

To maintain the appearance and functionality of your RD-8, regularly clean the unit:

• Use a soft, dry cloth to wipe down the exterior.
• For stubborn dirt, a slightly damp cloth with mild soap can be used, followed by a dry cloth.
• Avoid abrasive cleaners, solvents, or waxes, as these can damage the finish and components.
• Ensure no liquids enter the unit through openings or controls.

4.2 Storage

When not in use for extended periods, store the RD-8 in a cool, dry place, away from direct sunlight and extreme temperatures. It is advisable to use the original packaging or a protective case to prevent dust accumulation and physical damage.

4.3 Firmware Updates

Periodically check the Behringer website for new firmware updates. Keeping your device's firmware up-to-date ensures optimal performance, bug fixes, and access to new features.

5. Troubleshooting

This section addresses common issues you might encounter with your RD-8.

5.1 No Sound Output

• Check Power: Ensure the unit is powered on and the power adapter is securely connected.
• Volume Levels: Verify that the master volume, headphone volume, and individual instrument levels are turned up.
• Audio Connections: Confirm that audio cables are correctly connected to the main mix output or individual outputs and to your mixer/interface. If using individual outputs, ensure the corresponding instrument is not muted on the main mix.
• Mute/Solo: Check if any tracks are muted or if only one track is soloed.

5.2 Patterns Not Saving or Recalling Correctly

• Save Procedure: Ensure you are following the correct procedure to save patterns and songs. Refer to the "Song and Pattern Management" section.
• Firmware: An outdated or corrupted firmware can sometimes cause data saving issues. Ensure your RD-8 has the latest firmware installed. If issues persist, a factory reset (refer to Behringer support documentation) might be necessary, followed by a firmware re-installation.

5.3 MIDI/USB Synchronization Issues

• Sync Source: Verify that the RD-8's sync source (Internal, MIDI, USB) matches your master clock source.
• Cable Connections: Check MIDI and USB cable connections for proper seating.
• MIDI Channels: Ensure MIDI channels are correctly configured on both the RD-8 and your external device.

5.4 Unexpected Behavior

If the unit exhibits unexpected behavior not covered above, try the following:

• Power Cycle: Turn off the RD-8, disconnect the power, wait a few seconds, then reconnect and power on.
• Factory Reset: As a last resort, a factory reset can restore the unit to its default settings. Consult the official Behringer documentation for the specific procedure, as this will erase all user data.
