ADDAC702

Here's our first Voltage-Controlled Variable Filter, inspired by the original MS-20 filter.

This module features:

  .Two independent filters, a High-Pass and a Low-Pass with dedicated audio inputs and outputs. 

  .Besides individual outputs the HP and LP are also sent to a voltage-controlled Mix between the HP and LP filters.

  .Both Cutoff and Resonance are voltage-controlled with dedicated cv attenuator pots.

  .Switch for selecting between normal cutoff behaviour and an adjustable Smooth circuit to simulate a vactrol behaviour for cutoff control.

  .Switch for setting filters Filters in Parallel (independent) or Series (HP > LP).

  .Inspired by the Oscar synthesizer we added a Coupling switch to tie the HP Cutoff control to the LP Cutoff control, in this case the LP cutoff controls act as an offset from HP setting.

  .Three position switch selects different resonance clipping paths: diodes / no clipping / leds.

  .Both filters features a post Distortion/Fuzz circuit that adds extra harmonics adds an even deeper growl or extra gritiness to it.

  .All audio outputs (HP, Mix, LP) feature a switch for choosing phase output, allowing additive or subtractive mixes.

  .Three Leds monitor the amplitude of the three outputs (HP, Mix, LP).

In case you're wondering: Sure! We can get you a custom coloured front panel for the ADDAC702.
It has an additional cost and takes 4 to 6 weeks to be ready.

At the moment the ADDAC702 standard panel colour is Black.

A custom colour panel can be done in either Red, Green, Blue, White, Silver Gray, Yellowed Silver, and Dark or Light Bronze.

Print colour varies between Black, White, or Red, Blue and Green. We recommend lighter-tone print for darker panels, and vice-versa.

Please note: we don’t stock custom coloured panels. For every custom order we need to make a single panel order from our panel provider. This explains the panel price and lead time.

Thanks for your interest in the ADDAC702!
