ADDAC603

At ADDAC we’ve been in love with Bandpass Filters for a long time! We use them in several different ways but mostly as dynamic equalizers at the end of an audio chain for ever-changing timbral qualities with slow modulations on frequency and volume; slightly or drastically changing the character of the incoming sound by just controlling a few parameters and adjusting the modulation speed. And while this method is a personal preference of ours while developing such module we soon realized that some features would give it other aural qualities, so we started by adding a dedicated feedback control so that each filter could self-oscillate while making this control independent from the Bandwidth control. Also added an amplifier x3 or x100 at each of the inputs in order to create soft or hard distortions turning it into a controllable 3 band distortion!
 
 
Features:
3 independent Bandpass filters each with: 
Input gain up to x3 or x100 via a switch
VC Frequency with attenuverter
VC Bandwidth  with attenuverter
6 or 12db (1 or 2 poles) Switch
Resonance
Individual output VC Amplifier with attenuverter
Phase output switch
 
3 bands summing mix plus Dry control with attenuverter
 
Inputs are Normalled: 1->2->3 allowing for the three bandpass filters to be used either for the same input source or from three independent sources.
 
Filters and VCA’s developed with the modern version of SSM2164 from CoolAudio for pristine sound quality.
 
 
Tech Specs:

Note: All specifications and features are subject to change without previous notice.

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

It can be done in either Red, Green, Blue, White, Silver Gray, Yellow, or Gold.

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 ADDAC603!
