ADDAC106

This is the last module in our T-Networks series, a straightforward 4 voice module with frequency and decay controls for each of the voices. As the name already unveils we added a noise source and created 2 different circuits that explore the timbre of a t-network when used to filter noise.

There are 2 different circuits in this module: voices 1 to 3 have a pre-vca t-network filter while in voice 4 the t-networks filter applied post-vca.

At each voice input there’s a switch that sets which type of input to use; this signal will be used to control an internal VCA hence why the type of setting defined here is important:
1. Trigger - Any incoming CV will be converted into a 1ms trigger as soon as it crosses its fixed threshold.
2. Mute - This disconnects then incoming signal effectivelly muting the voice.
3. Envelopes - This can be used with CV sources as well as Gate sources and simply follows the input signal.

This incoming signal will then be processed by a slew circuit which adds a decay factor allowing the user to set the “Tail” of each voice.

Trigger mode is mostly dedicated for percussive sounds while the Envelope mode is open to any external envelope control and able to control noise swooshes, swirls, crackles and pops simply out of t-networks filtered noise.

Audio inputs also welcome use as a Trigger/Envelope input, in fact the results of using this method had us all extremely surprised, so please do try it out!

Diferences between voices:
The first 3 voices also feature a Timbre selector switch: Hat/Snare
In Snare mode all frequencies coming from the t-networks filter pass through to the output .
In Hat mode it adds a High Pass circuit which removes the mid/bottom frequencies (characteristic of the snare strike) creating a higher spectrum output which is closer to a Hat timbre.
All of these 3 voices are also differently tuned from each other to offer more timbrical options.

Voice 4 is closer to a typical t-networks circuit but this time a peculiar one where the noise is gated by the vca and then sent through the t-networks filter.

Hat and Snare are terms used very loosely here; they are timbrical references and do not in any shape or form try to effectively replicate the complex timbres of a real world Hat or Snare.

In case you're wondering: Sure! We can get you a custom coloured front panel for the ADDAC106.
It has an additional cost and takes 4 to 6 weeks to be ready.

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, Yellow, 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 ADDAC106!

DIY Kit for Eurorack Module

Please read this safety guide before installation or use.

Important Notice & Intended Use
• This kit is intended for adult users experienced in electronics and modular synthesis.
• Assembly, including soldering, is required.
• Proper testing and installation are essential to ensure safe and functional operation.
• The completed module is intended for installation in a Eurorack-compatible synthesizer system powered by ±12V and +5V.
• Use outside this scope may result in malfunction, damage, or safety risks.

General Warnings

Electrical Hazards:
• Ensure the power supply matches the module’s specified voltage and current ratings (refer to the product manual). Incorrect voltage can damage the module and pose a safety risk.
• Never connect or disconnect the module while the Eurorack system is powered on.
• Wrong polarity can damage your module or system. Make sure the module is connected with correct polarity.
