ACL Dual State Variable VCF Owner's Manual

ACL Dual State Variable VCF is a versatile Eurorack synthesizer module containing two 12dB multimode VCFs (A and B) with Lowpass, Bandpass, Highpass, and Notch outputs. Each filter can be controlled individually or simultaneously, offering both parallel and serial routing options. Both filters can be controlled with CV inputs for Cutoff and Resonance, all with attenuverters for signal strength adjustments.

1. INTRODUCTION
Audiophile Circuits League. -DUAL STATE VARIABLE VCF module contains two
12dB multimode VCF´s A and B, with Lowpass, Bandpass, Highpass and
Notch-Output. Both �ilters A and B can be controlled individually and
simultaneously in the same time. Filters can be routed in parallel or serial
con�iguration. All Audio and CV-inputs are normalized from �ilter A→B. CV
inputs for Cutoff and Resonance of each �ilter got a attenuverter.
(For details about normalization, see section 5. CHARACTERISTICS)

Frequently asked questions

The CV inputs allow you to modulate the filter's cutoff frequency and resonance using external control signals, like LFOs or envelopes. The attenuverters on the CV knobs let you adjust the signal strength for fine control.

In parallel mode, the two filters operate independently. In serial mode, the audio signal from filter A passes through filter B, allowing for complex filtering effects.

Yes, the 1V/OCT input jack allows you to use the module as a substitute for an oscillator using self-oscillation. You can connect a scale to this input for pitch control.
