Analog synthesizer Behringer TD-3-SB Red 9V DC

The Behringer TD-3-SB Red is a compact analog synthesizer inspired by classic bassline machines, presented in a durable red finish. It runs on 9V DC power and has a compact footprint (305 mm wide, 165 mm deep, 56 mm high) with a lightweight construction of 1.4 kg, making it easy to carry and integrate into studio rigs or live setups. The instrument features a pure analog signal path with authentic VCO, VCF and VCA circuitry, an integrated 16-step sequencer and distortion circuitry for additional tonal shaping.

Advantages

The TD-3-SB provides a true-to-original analog sound path using matched transistors and transistor-based wave-shaping for sawtooth and square/pulse waveforms. Its 24 dB/octave low-pass filter with cutoff and resonance controls allows precise timbre shaping, and the onboard distortion adds grit and presence when required. With a ready-to-play layout and direct-access controls, the unit is practical for immediate sound design and live performance without complex patching.

Suitable for

• Producing basslines and lead parts in electronic music genres
• Studio sound design and hardware-based synthesis workflows
• Live performances and DJ setups that require compact analog synths
• Educational use for learning analog synthesis and sequencing

How to use

Connect the TD-3-SB to a 9V DC power source and route its audio output to a mixer, audio interface or amplifier. Use the VCO waveform selector and tuning controls to choose and shape the basic tone, then sculpt the sound with the filter Cutoff, Resonance and envelope controls. Program patterns on the 16-step sequencer in Step mode or record in Keyboard mode; store patterns into groups for quick recall. Engage the Distortion switch and adjust Drive for added grit when needed. For synchronized setups, connect via MIDI or USB to external gear or a computer.

Recommendations

For stable performance in live or studio environments, place the TD-3-SB on a flat surface and avoid exposing it to strong vibration or moisture. When combining multiple units in Poly Chain mode, verify connections and power sources before powering up. To preserve the instrument, use the recommended 9V DC adapter and disconnect power when not in use.
