Low Pass 

Ladder Filter 

This VOLTAGE CONTROLLED LOW PASS FILTER is a traditional ladder-type filter, switchable 12/18/24 dB/oct with voltage controllable cutoff frequency and regeneration.

M 505

Voltage Controlled Multi Mode Filter

The MULTI MODE FILTER features low pass, high pass, band pass (12 dB/oct each) and notch mode (6 dB/oct), which are available simultaneously as well as combined at the mixed output, where the filter mode is voltage controlled. Cutoff frequency and resonance are voltage controllable too.

M 506

Voltage Controlled Modifier

The MODIFIER module is a combination of voltage controlled low pass filter and voltage controlled amplifier connected in series. 

The VCF is a ladder type lowpass filter featuring switchable slopes (12/18/24 dB/oct) and voltage controllable regeneration. In addition to the manual frequency and resonance dials there are three attenuated control voltage inputs for filter cutoff (bipolar), resonance and amplifier gain. 

The VCA bypass switch opens the amplifier.

Coupled Dual Voltage Controlled

High Pass/Low Pass Filter

This module combines two VOLTAGE CONTROLLED FILTER circuits in one triple-width unit. The two identical filters are switchable high pass/low pass filters with independent controls for cutoff frequency and regeneration. 

The four-mode combinator allows using the filters as – two separate filters (”stereo mode“) – two filters in series (”maximum slope“) – notch/band reject mode – band pass mode. 

The balance between filter 1 and 2 and the bandwidth are voltage controllable. 

An additional jack combines both filters' audio outputs.

Voltage Controlled

High Pass/Low Pass Filter

The SINGLE VOLTAGE CONTROLLED FILTER is one half of the 517 module without the combinator part, featuring a single high pass/low pass filter with voltage controllable cutoff frequency and regeneration.
