BEHRINGER / FILTAMP MODULE 1006

BEHRINGER Eurorack modular synthesizer, reproducing the circuitry of the original System 2500 from the 70s. Analog voltage controlled low pass filter and VCA module.

Features
70s classic 1006 analog FiltAmp module
Full-scale reproduction of the “2500” series circuit
24 dB transistor ladder low-pass filter followed by discrete VCA
Filter cutoff frequency can be controlled by external control voltage and frequency control
Three external VCF control voltage inputs with variable attenuation respond at 1 V/octave
Resonance or “peak” response at cutoff can be adjusted with the resonance control
Two audio signals can be mixed and their relative amplitudes adjusted.
VCAs receive output from the VCF and modify the output signal level according to the sum of the gain control voltage and the external control voltage.
The two external VCA control signals can be attenuated by front panel control.
The VCA mode can be selected from either the Esponential or Linear mode.
Eurorack specifications: 16 HP, +12V, -12V
