ADDAC803

This is our Quadraphonic output module.
Using the VBAP (Vector-Base Amplitude Panning) principle it allows to position a mono signal over a quadraphonic speaker array for sound spatialization. The VBAP algorithm can be controlled by Cartesian or Polar methods

Sound path is fully analogue featuring 4 high quality VCA's.
Featuring both 1/4 inch and 3.5mm jacks for adapter free connections.

Four 16 bit CV outputs mirror the signal sent to the VCA's control, when connected to 4 external VCA's these can be used for Polar Mixing of 4 diferent sound sources.

The 2 Filter CV outputs react according to the distance from the center point. The + output increases as the sound gets further away from the center of the room allowing to sync a Low Pass Filter to the input sound so that as it moves away from the center the High Frequencies get attenuated further increasing the spatialization experience. Another good practice would be to sync a reverb dry/wet signal as well so that the sounds gets more difused as it moves away from the center into the horizon.
Both the filter and the reverb should be plugged between the sound source and the 803, in order for the incoming sound to be processed before being routed to the 4 outputs.

The X and Y CV outputs mirror the cartesian sound position between 0 and +5v.

In case you're wondering: Sure! We can get you a custom coloured front panel for the ADDAC803.
It has an additional cost and takes 4 to 6 weeks to be ready.

At the moment we have standard issue stock for either Black or Red panels for this module

A custom colour panel can be done in either 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 colored 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 ADDAC803!
