Digital loudspeaker management system

C3-ControllerThe DFM high performance DSP architecture provides excellent audio characteristics that allow even the most demanding solutions.

Serial bus system with corresponding NetControl PC Software allows managing several C3 controlers as a groupable network in real time. This possibility is also supplemented in two variants which differ by managing the parameters.


The C3-EQ is a fully adjustable audio controller. For inputs and outputs parameters like filters, bands and so on are separatly adjustable.


At the C3-Controller only the inputs are abjustable. The outputs are adjustable by predefined presets made from the OEM manufacturer. The presets are made for the present speakertype only.
