Offer Details

The Stereo Dipole is a versatile Quad Multi-Mode Voltage-Controlled Filter (VCF) offering single, dual, and quad peak filter outputs.
This module is designed to be both clean and characterful, without targeting a specific sound. It excels in applications ranging from clean frequency-based panning to complex phasing, formant synthesis, and overdriven, squelchy bass lines. Simple yet powerful, the Stereo Dipole provides a user-friendly interface while encouraging sonic experimentation and exploration.
Key Features:
Dual Identical Filter Sections:
Operable independently or together using dedicated controls:
RES: Resonance
FREQ: Primary Cutoff
SPREAD: Secondary Cutoff
Central controls for stereo functionality:
STEREO FREQ: Stereo Cutoff
STEREO RES: Stereo Resonance
Filter Outputs:
Each channel (Left and Right) offers:
Single Peak (POLE) and Dual Peak (DIPOLE) outputs
Switchable High Pass, Low Pass, and Band Pass outputs located above the POLE and DIPOLE controls.
Routing Flexibility:
The Dual Peak DIPOLE output can be routed in Series or Parallel with the main POLE VCF, enabling a wide range of configurations:
24dB/OCT HP/BP/LP
Variable-width Band Pass
Notch filtering
Unique and experimental filter combinations
Control Parameters:
FREQ: Adjusts the cutoff for both primary and secondary filters.
SPREAD: Matches or offsets the secondary cutoff frequency by +/-5 octaves.
Advanced Outputs:
DIPOLE AB: A Quad Peak Monophonic Output with shared routing and topology options for the four VCF cores.
The A input (Left) normalizes into the B input (Right), creating stereo imaging from a monophonic source.
Pre-Filter Input DRIVE:
Soft-clipping and saturation controls on each channel add harmonic content and enhance low-end richness. Even a sine wave can be overdriven for warm, musical results.
Resonance Control:
Ranges from subtle to full self-oscillation across 20+ octaves.
Oscillator and LFO Capabilities:
All VCF cores track 1V/OCT and are temperature-compensated, enabling use as single, dual, or quad sine wave oscillators or LFOs.
Series routing expands tonal oscillation options via DIPOLE and DIPOLE AB outputs.
CV Inputs and Attenuation:
Individual and stereo CV inputs for STEREO RES, RES A/B, and STEREO FREQ.
Polarizing attenuators for FM CV inputs on each channel.
SPREAD CV inputs allow direct and accurate 1V/OCT control of secondary peaks.
Visual Feedback:
RGB LEDs display cutoff frequency and resonance positions.
Build Quality:
Reverse power protection
Soft-start power-on system
High-fidelity components
The Stereo Dipole is a dynamic tool that caters to intricate sound design, offering unparalleled flexibility for both mono and stereo applications.
