Hungry Robot Modular VCF


Maker: Hungry Robot

Model: VCF

Condition: New

 

Description:  

The Hungry Robot VCF is an all analog, 4-pole low pass filter with a self-oscillating resonance control.  It is a close replication of the filter circuit found on the famous Prophet 5.  It uses a HM2040 which is a high quality, faithful replication of the original SSM2040 chip.  This resonant filter has a beautiful tonal quality.  The over-sized knobs provide a satisfying tactile response.  The cutoff frequency can be controlled by external control voltage.  It has a built-in attenuator and invert switch for the incoming CV.  CV input does not track at 1V/Oct, but is scaled to act as a VCA when a 5V signal is applied to CV input.  As with all Hungry Robot "Modular Boxes" the VCF can be powered by a simple 9V DC, Negative Center power supply.  


KNOBS 

   -FREQUENCY:  Sweeps the cutoff frequency of the filter.

   -CV:  Attenuator for incoming CV input.  

   -RESONANCE:  Sets resonance of filter.  Small volume drop is to be expected.  Will self-oscillate at higher settings.

SWITCHES
   -INVERT:  Inverts the incoming CV input.  Toggle to the right to invert incoming CV


PATCH POINTS 

   -IN:  Patch Audio Signal In

   -CV:  CV input for Frequency.  Allows for CV control of this parameter.  

   -OUT:  Patch Audio Signal Out

 

Dimensions: 4.7” x 2.6” x 1.5”

Power: 9V DC - Negative Center - 2.1mm Barrel

(ISOLATED SUPPLY PREFERABLE)
