FURIA

Olivella Modular

Fully discrete 4-pole transistor ladder LPF (based on E-mu Modular 2100) and an all-transistor vintage-style VCA with variable CV response curve, pre-filter saturation, and selectable AC/DC coupling via rear DIP switches.337

Capabilities 2

Ladder Filterladder-filter
Discrete 4-pole transistor ladder LPF at -24dB/oct based on the E-mu Modular 2100; no ICs in audio path.337
Voltage-Controlled Amplifiervca
All-transistor VCA with variable CV response curve (linear to exponential) and X10 impedance switch for distortion.337

Jacks 3

NameSignalVoltageDescription
Inputs (3)
AMP CVcvCV input for the VCA with attenuverter; normalled to FREQ CV input for LPG-like operation. Accepts audio-rate modulation.337
AMP INaudioAudio input that mixes a signal directly into the VCA after the filter stage. The X10 switch changes its impedance from 100kΩ to 10kΩ.337
FREQ CVcvCV input for the VCF cutoff frequency, with attenuverter. Accepts audio-rate modulation.337

Parameters 4

NameTypeRangeBehavior
AMP CV response curvemenu_settingControls the VCA CV response curve continuously from linear to exponential.337
DIP switchjumperLocated on the rear panel; allows selective AC-coupling of VCF and VCA inputs/outputs, and changing the VCF→VCA normalling for series, parallel, or independent use.337
INPUT LEVELknobControls pre-filter input gain; starts distorting around 9 o'clock and interacts with resonance.337
X10 switchswitchReduces the VCA input impedance tenfold (from 100kΩ to 10kΩ), enabling distortion or pre-amplification of external sources.337
