ADDAC System ADDAC803 VC QUADRAPHONIC SPATIALIZER 2011 - Black

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.

LEAD TIME - IMPORTANT NOTE:
Although this is also described in our Shop Policy page, it is worth stressing that, by virtue of being a small team and not outsourcing a great part of our production, long story short, we sort of make your order on demand.
After you place an order, it takes up to 15 business-days to be ready to ship.
This is why you'll see this module as 'in stock', but this in fact means that we do have all its parts and can produce your module. Thanks for understanding, and for choosing us!
