Behringer 112 DUAL VCO Specification

The Behringer 112 DUAL VCO is a Eurorack-format analog oscillator module designed for modular synthesizer systems, delivering classic voltage-controlled oscillator functionality with modern precision. Each of the two independent VCOs in the module offers a wide range of features, including five waveform outputs: sine, triangle, sawtooth, pulse, and PWM, allowing for diverse sound shaping capabilities. The module offers precise frequency control over a 10-octave range, with both coarse and fine tuning knobs to ensure optimal pitch accuracy and flexibility during performance or sound design.

Each oscillator supports pulse-width modulation, a crucial feature for creating rich, evolving tones and harmonics. The pulse width can be manually adjusted or modulated via external control voltage inputs, enhancing the dynamic potential of the module. Additionally, exponential and linear frequency modulation inputs are provided, allowing for complex cross-modulation scenarios between the oscillators or with external CV sources. The 112 DUAL VCO is equipped with a sync input for hard synchronization, enabling tight sonic alignment between oscillators, which is particularly useful for creating harmonically rich and percussive sounds.

The module is designed to fit into any standard Eurorack case, occupying 16 HP of rack space and requiring a typical power supply of +/-12V, drawing a current of 50 mA per rail. Through its robust and versatile feature set, the Behringer 112 DUAL VCO caters to both experimental sound designers and traditional synthesists, offering a powerful tool for crafting a wide array of analog tones. Its design reflects a balance between vintage analog warmth and modern synthesis demands, making it an ideal addition to any modular setup.

Behringer 112 DUAL VCO F.A.Q.

How do I calibrate the Behringer 112 DUAL VCO for accurate tuning?

To calibrate the Behringer 112 DUAL VCO, ensure your system is powered on for at least 15 minutes to stabilize. Use a tuner to adjust the pitch using the front panel trim pots until the desired notes are achieved across the octaves.

What is the best way to patch the Behringer 112 DUAL VCO for a bass sound?

For a bass sound, patch the sawtooth wave output to your filter module, then adjust the filter cutoff to emphasize low frequencies. Modulate the VCO with a slow LFO for subtle pitch variation.

How can I troubleshoot if there is no sound output from the Behringer 112 DUAL VCO?

First, ensure all cables are securely connected. Check the power supply and make sure the module is properly seated in the Eurorack. Verify that the waveform and frequency knobs are set to audible ranges.

What should I do if the frequency of my Behringer 112 DUAL VCO drifts unexpectedly?

Frequency drift can be minimized by allowing the module to warm up before use. If the issue persists, recalibration may be necessary. Ensure the module is not exposed to temperature fluctuations.

Can I use the Behringer 112 DUAL VCO in a polyphonic setup?

Yes, you can use multiple Behringer 112 DUAL VCOs in a polyphonic setup by patching each to separate voices in your modular system, assigning different MIDI channels for polyphony control.

How do I create FM synthesis using the Behringer 112 DUAL VCO?

For FM synthesis, connect the output of one VCO to the FM input of another. Adjust the modulation depth and frequency to achieve desired timbres. Experiment with different waveforms for varied results.

What maintenance is required for the Behringer 112 DUAL VCO to ensure longevity?

Regularly clean the module with a soft, dry cloth to prevent dust buildup. Check connections and recalibrate periodically. Store in a stable environment to avoid temperature and humidity extremes.

How can I achieve a vintage sound using the Behringer 112 DUAL VCO?

To achieve a vintage sound, use the triangle or sine wave outputs for a softer tone. Pass the signal through a low-pass filter and apply subtle modulation with a slow LFO to emulate classic synth sounds.

What power specifications should I consider when integrating the Behringer 112 DUAL VCO into my Eurorack setup?

Ensure your power supply can handle the module's power requirements: +12V, -12V, and +5V if necessary. Check the total current draw of your system to prevent overloading the power supply.

How do I sync the Behringer 112 DUAL VCO with other modules in my setup?

Use the sync input to synchronize the VCO with another oscillator. Connect the sync output of another module to the sync input of the 112 DUAL VCO for phase alignment and stable tuning.
