Behringer 1006 FILTAMP Module – Voltage Controlled Filter & Amplifier for 2500 Series Modular Synthesizer

Patch the Behringer 1006 FILTAMP Module into your 2500 Series system and sculpt sounds with surgical precision. A sound designer in a Berlin studio uses it to carve sweeping resonant textures from a raw sawtooth, while a live performer in Tokyo tweaks the cutoff on the fly for dramatic filter sweeps. This dual-function module combines a multi-mode voltage controlled filter and a voltage controlled amplifier, giving you classic analogue tone shaping in a compact Eurorack-compatible format.

Key specifications

• Voltage Controlled Filter (VCF) with Low-Pass, High-Pass, Band-Pass and Notch modes
• 24 dB/octave (4-pole) filter slope for steep, musical cutoff
• Voltage Controlled Amplifier (VCA) with dedicated gain control
• 2 audio inputs and 3 CV inputs (Frequency, Resonance, Q) on the VCF
• 2 audio inputs and 2 CV inputs (Gain) on the VCA
• Manual controls for Frequency, Resonance (Q), Input Level and CV attenuators
• Separate VCF and VCA outputs for flexible signal routing
• Runs on standard Behringer 2500 Series power: +15V / -15V DC, ~50mA per rail

Why choose it

The 1006 FILTAMP delivers the legendary 2500 series character without the vintage price tag. Its multi-mode filter lets you go from silky low-pass warmth to piercing high-pass bite, while the built-in VCA handles everything from subtle level control to aggressive amplitude modulation. All controls are laid out for hands-on performance, and the module integrates seamlessly with other Behringer 2500 Series modules or any Eurorack case with the appropriate power.

Ideal use cases

• Classic subtractive synthesis: filter a rich oscillator through the low-pass mode for fat basses and leads
• Sound design: use band-pass and notch modes to create vocal-like formants and metallic timbres
• Modular processing: route external audio through the VCF and VCA for dynamic filtering and gating
• Live performance: tweak frequency and resonance in real time for expressive filter sweeps
• Educational setups: teach voltage control concepts with a clear, hands-on module

Good to know

The module is part of Behringer's authentic recreation of the ARP 2500 system, known for its matrix switching and distinctive sound. It requires a compatible case with +15V and -15V power rails, such as the Behringer Eurorack Go or other 2500 Series enclosures. Patch cables are not included. For best results, pair it with a Behringer 1004 VCO or 1027 Sequencer to build a complete voice.
