Synthesis Technology E440 Discrete OTA VC Lowpass Filter

The E440 from Synthesis Technology is a low-pass VCF with three outputs, each occupying a different slope of the filter: 2 pole, 3 pole, and 4 pole. Two CV inputs control the cutoff frequency, while the third controls the resonance. The module is capable of self-oscillation at higher rates for use as a sine-wave VCO with 1V/Oct tracking and a four-octave range.

E440 Features

• Resonance goes into tasty self-oscillation
• Standard and inverting FM inputs with dedicated FM amount controls
• Drive up to 2x gain
• AUDIO IN can be any level up to 14V pk-pk
• Individual 2-pole, 3-pole, and 4-pole outputs
