Behringer 140 DUAL Envelope LFO Specification

The Behringer 140 DUAL Envelope LFO is a versatile Eurorack module designed for synthesizers, offering dual envelope generators and a low-frequency oscillator (LFO) for dynamic sound shaping capabilities. Each envelope generator provides controls for attack, decay, sustain, and release (ADSR), allowing users to craft precise amplitude and modulation envelopes. The module features a range of envelope modes, including linear and exponential, to achieve distinct sonic characteristics. The LFO section boasts multiple waveform outputs such as sine, triangle, and square waves, enhancing modulation possibilities. It operates across a wide frequency range, making it suitable for both audio-rate modulation and slow, evolving modulations. The module includes CV inputs for external control over envelope and LFO parameters, enabling complex modulation routings. Its compact design fits seamlessly into Eurorack setups, offering a robust toolset for sound designers and musicians seeking intricate modulation capabilities. With its high-quality build and intuitive interface, the Behringer 140 DUAL Envelope LFO is an essential component for expanding the sonic potential of any modular synthesizer system.

Behringer 140 DUAL Envelope LFO F.A.Q.

How do I connect the Behringer 140 DUAL Envelope LFO to my modular setup?

To connect the Behringer 140 DUAL Envelope LFO to your modular setup, use patch cables to connect the module's output jacks to the inputs of other modules in your system. Make sure the power supply is connected correctly, with the red stripe on the ribbon cable aligned with the -12V marking on the module and power bus.

What is the function of the LFO in the Behringer 140 module?

The LFO (Low-Frequency Oscillator) in the Behringer 140 module generates cyclical waveforms that can modulate other parameters in your modular setup, such as pitch, filter cutoff, or amplitude, creating dynamic and evolving sounds.

How can I troubleshoot if the envelopes are not triggering properly?

If the envelopes are not triggering properly, ensure that the gate or trigger signals are reaching the module. Check the patch cables and connections. Verify that the signal source is functioning correctly and refer to the module's manual for any specific settings that might affect triggering.

Can the Behringer 140 DUAL Envelope LFO be used to modulate filter cutoff?

Yes, the Behringer 140 DUAL Envelope LFO can be used to modulate filter cutoff. Patch an output from either the envelope or LFO section to the cutoff frequency input of your filter module to achieve modulation effects.

What maintenance is recommended for the Behringer 140 module?

Regular maintenance for the Behringer 140 module includes ensuring it is kept free from dust and debris, checking for secure cable connections, and verifying that the power supply is stable. Periodically inspect the module for any signs of wear or damage.

How do I adjust the attack and decay times on the Behringer 140 module?

To adjust the attack and decay times on the Behringer 140 module, use the respective knobs labeled 'Attack' and 'Decay' in the envelope section. Turning the knobs clockwise increases the time, while turning them counterclockwise decreases it.

What should I do if the LFO is not oscillating?

If the LFO is not oscillating, check the power supply connection, ensure the module is properly seated in the rack, and verify that the rate control is set above zero. If issues persist, consult the manual or consider a professional inspection.

Is it possible to sync the LFO with an external clock?

Yes, it is possible to sync the LFO with an external clock by patching a clock signal into the LFO's frequency modulation input. This allows the LFO to modulate in time with your clock source.

Can I use the Behringer 140 to generate both audio and control signals?

The Behringer 140 is primarily designed for generating control signals with its envelope and LFO sections. However, at higher rates, the LFO can produce audio-rate modulations, which can be used creatively in sound design.

How can I extend the range of modulation using the Behringer 140 module?

To extend the range of modulation, you can use external attenuators or CV processors to scale the output of the Behringer 140. Additionally, combining it with other modulation sources can create more complex and varied results.
