1. Introduction
This manual provides essential information for the proper setup, operation, and maintenance of your Behringer TD-3-RD Analog Bass Line Synthesizer. The TD-3-RD is an analog bass line synthesizer featuring true analog circuitry for bass and groove sounds, an authentic reproduction of original circuitry with matched transistors, and a pure analog signal path based on legendary VCO, VCF, and VCA designs. It includes a sawtooth and square waveform VCO with transistor wave-shaping circuitry and a four-pole low-pass resonant filter with cut-off, resonance, envelope, decay, and accent controls.

5. Setup
Follow these steps to set up your TD-3-RD synthesizer:
- Power Connection: Connect the provided power adapter to the DC INPUT on the rear panel of the TD-3-RD and then to a suitable power outlet. Ensure the power switch is in the OFF position before connecting.
- Audio Output: Connect the OUTPUT jack on the rear panel to your mixer, audio interface, or amplifier using a standard 1/4-inch TS cable.
- MIDI Connections (Optional): For MIDI control, connect a MIDI cable from your MIDI controller or interface's MIDI OUT to the TD-3-RD's MIDI IN. If chaining multiple MIDI devices, use the MIDI THRU port.
- USB Connection (Optional): Connect a USB cable from the TD-3-RD's USB port to your computer for MIDI over USB functionality and firmware updates.
- Power On: Flip the power switch on the rear panel to the ON position.
6. Operating
The TD-3-RD offers a range of controls for sound generation and sequencing. Familiarize yourself with the main sections:
6.1. Sound Generation (VCO, VCF, VCA)
- VCO (Voltage Controlled Oscillator): Select between Sawtooth and Square waveforms using the WAVEFORM switch. The VCO generates the fundamental tone of your sound.
- VCF (Voltage Controlled Filter): This is a 4-pole low-pass resonant filter. Adjust the following knobs to shape the timbre:
- CUTOFF: Determines the frequency at which the filter starts to remove higher frequencies.
- RESONANCE: Boosts frequencies around the cutoff point, creating a distinctive 'wah' or 'squeal' effect.
- ENVELOPE: Controls the amount of envelope modulation applied to the cutoff frequency.
- DECAY: Sets the decay time of the VCF envelope.
- ACCENT: Adds a dynamic emphasis to notes, affecting both volume and filter cutoff.
- VCA (Voltage Controlled Amplifier): The VCA controls the overall volume of the sound, influenced by the envelope and accent.
6.2. Sequencer
The TD-3-RD features a 16-step sequencer for creating rhythmic bass lines.
- MODE: Switch between WRITE (for programming patterns) and PLAY (for playing patterns).
- TRACK/PATTERN GROUP: Organize your patterns into tracks and groups.
- PITCH MODE: Select the input method for pitch data (INT for internal keyboard, MIDI, USB, TRIG).
- TIME MODE: Adjust timing parameters and step resolution (e.g., 1PPQ, 2PPQ, 24PPQ, 48PPQ).
- STEP Buttons (1-16): Used for entering notes and parameters in WRITE mode, and for pattern selection.
- ACCENT/SLIDE: Buttons to add accent and slide effects to individual steps in a sequence.
- WRITE/NEXT: Used to save patterns and advance in programming.
- START/STOP: Initiates or halts sequence playback.
- TEMPO: Adjust the playback speed of the sequencer.
6.3. Distortion Effects
The built-in distortion circuit adds grit and aggression to your bass lines.
- DISTORTION Switch: Toggle the distortion effect ON or OFF.
- TONE: Adjusts the tonal character of the distortion.
- LEVEL: Controls the output level of the distorted signal.
7. Maintenance
Proper care ensures the longevity and optimal performance of your TD-3-RD.
- Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Do not use abrasive cleaners or solvents.
- Storage: Store the synthesizer in a cool, dry place away from direct sunlight and extreme temperatures.
- Transportation: When transporting, use the included bag or a suitable case to protect the unit from physical damage.
8. Troubleshooting
If you encounter issues with your TD-3-RD, refer to the following common problems and solutions:
- No Sound:
- Check power connection and ensure the unit is turned ON.
- Verify audio cable connections to your mixer/interface.
- Ensure the VOLUME knob on the TD-3-RD is turned up.
- Check the master volume on your mixer/interface.
- Sequencer Not Playing:
- Ensure the MODE switch is set to PLAY.
- Press the START/STOP button.
- Check if a pattern is loaded or programmed.
- MIDI Not Responding:
- Verify MIDI cable connections.
- Check MIDI channel settings on both the TD-3-RD and your controller/software.
- Ensure the PITCH MODE is set to MIDI or USB if applicable.
