This product is in stock now. If you order it, it will be shipped within 24 hours (see terms & conditions).
The WMD Quad Anti Aliasing Filter (QAAF) was conceptualized as the first epansion for the Phase Displacement Oscillator. It is designed to eliminate aliasing and stair-step distortion from the Digital to Analog converters. We opted to make this a seperate module because it is useful by itself as well as coupled with the PDO.

There are four independent filters inside the QAAF. Each -24dB/octave Butterworth filter runs at exactly the same frequency. The Butterworth filter has a small amount of resonance and a great sound. Each input jack is normaled from the expansion header that connects to the PDO, but any signal can be filtered by plugging in.

The frequency control circuitry uses a vactrol to control the clocking speed of each filter, slowing down the response to transient signals. This brings life and character to the sound.

  • Four 4-pole filters
  • Channel to Channel Freq +-0.5%
  • Switched Capacitor Design
  • Butterworth Response Curve
  • CV Input
  • Frequency Offset Knob
  • Clock Input/Output
  • Mix Output
  • Low-Frequency Limit Jumper
  • 4 HP
  • Great for Pre & Post Filtering
