Modular synthesizer multimode filter Behringer 1047 2500 Series

Behringer 1047 2500 Series is a multimode filter module for the 2500 Series modular synthesizer format. The module offers selectable filter modes that allow precise shaping of audio signals, control of resonance, and manipulation of frequency content. Designed for integration into compatible modular racks, the 1047 is intended for sound design, synthesis and live performance setups where flexible tonal shaping is required.

Advantages

The Behringer 1047 provides multiple filter modes in a single module, enabling low-pass, high-pass and band-pass responses to be selected for different timbral needs. It delivers adjustable resonance for emphasizing harmonics and creating sweeps, while its format ensures compatibility with standard 2500 Series racks. The straightforward control layout makes it practical for both studio patching and stage use, and its analog-oriented design supports classic filter behaviors useful in a wide range of electronic music styles.

Suitable for

• Modular synthesis patching in 2500 Series racks
• Sound design for electronic music and experimental textures
• Live performance setups requiring on-the-fly timbre control
• Integration with oscillators, VCAs and envelope generators

Key specifications

• Multimode filter: selectable low-pass, high-pass and band-pass responses
• Resonance control for peak emphasis and self-oscillation potential
• Control inputs and outputs compatible with the 2500 Series modular format
• Compact panel layout suitable for modular rack mounting

How to use

Patch the audio source output into the module's input and route the selected filter output to the next module or mixer. Use the mode selector to choose the desired filter response and adjust the cutoff frequency control to sculpt the tonal balance. Increase resonance to emphasize harmonics or create characteristic filter sweeps; reduce resonance for cleaner filtering. When using control voltage sources, patch CV to the filter cutoff input to automate frequency movement in sync with envelopes or LFOs.

Usage recommendations

For stable operation, mount the module in a compatible 2500 Series rack and ensure proper power and grounding. Start with moderate resonance settings when patching with high signal levels to avoid unintended distortion. Use CV control for dynamic modulation and combine the filter with envelopes and effects to expand its sonic possibilities.
