Behringer 921B Oscillator Specification

The Behringer 921B Oscillator is a meticulously engineered modular component designed for precise sound synthesis within Eurorack systems. It serves as a voltage-controlled oscillator (VCO) that is integral to modular synthesizers, offering superior sound quality and versatility. The 921B is part of Behringer’s modular synthesizer range and is built to replicate the classic analog warmth and precision of vintage oscillators. It features an extensive frequency range, extending from 0.01 Hz to 40 kHz, allowing it to generate anything from subsonic tones to ultra-high frequencies. This oscillator module is designed to produce multiple waveform outputs simultaneously, including sine, triangle, sawtooth, and square waveforms, each known for their distinct sonic characteristics, enabling complex sound design possibilities.

The 921B operates as a slave oscillator and requires a 921A Oscillator Driver for frequency control, ensuring stable and accurate pitch tracking across its range. This separation of control and output modules enhances the precision and flexibility of the system. The front panel is equipped with high-quality rotary controls that allow manual tuning adjustments, providing intuitive usability. It is housed in a compact, durable design, adhering to the Eurorack format with a width of 8HP, making it an efficient addition to any modular setup. Connectivity is facilitated through standard 3.5mm jacks, making integration with other modular components seamless. The Behringer 921B Oscillator promises to deliver classic analog sounds with modern reliability, catering to both vintage enthusiasts and contemporary sound designers seeking authentic analog tones.

Behringer 921B Oscillator F.A.Q.

How do I connect the Behringer 921B Oscillator to my modular synth setup?

To connect the Behringer 921B Oscillator to your modular synth, use patch cables to link the oscillator’s outputs to your mixer or other modules. Make sure the power supply is connected according to the manufacturer's specifications.

What are the basic waveforms available on the Behringer 921B Oscillator?

The Behringer 921B Oscillator provides sine, triangle, sawtooth, and square waveforms. These can be selected using the waveform output jacks on the module.

How can I troubleshoot if the Behringer 921B Oscillator is not producing sound?

First, ensure that the module is properly powered and all cables are securely connected. Check the waveform output and the amplitude settings. If the problem persists, try different patch cables and verify the module is not muted or bypassed in your system.

What should I do if the tuning of the Behringer 921B Oscillator drifts?

Allow the oscillator to warm up for a few minutes before use, as temperature changes can affect tuning. If the drift continues, manually calibrate the tuning knobs or refer to the user manual for recalibration instructions.

How do I perform a factory reset on the Behringer 921B Oscillator?

The Behringer 921B Oscillator does not have a factory reset function as it is an analog module. Any adjustments must be done manually.

What maintenance is required for the Behringer 921B Oscillator?

Regular maintenance involves keeping the module clean and free from dust. Use a soft, dry cloth to wipe the panel and avoid using any solvents. Periodically check connections and cables for wear.

Can the Behringer 921B Oscillator be used with other brands of modular synths?

Yes, the Behringer 921B Oscillator is compatible with other Eurorack modular systems, allowing for integration with various brands and modules.

What is the frequency range of the Behringer 921B Oscillator?

The Behringer 921B Oscillator typically covers a frequency range from approximately 0.03 Hz to 20 kHz, allowing for both sub-audio and audio applications.

Why is there no sound when I patch the square wave output on the Behringer 921B Oscillator?

Check the level and pulse width settings of the square wave output. Ensure the patch cables are properly connected and the destination module is set to receive the signal.

How do I synchronize the Behringer 921B Oscillator with another oscillator?

Use the sync input on the Behringer 921B to connect it to another oscillator's sync output. This will force the 921B to align its waveform phase with the master oscillator.
