Easy-to-use Controller
The ZEN Active Control System unit can be controlled via a friendly PC user interface. The High-Speed USB-2
connection allows to set the parameters of the controller, but also to see in real time the different signals and filters of
the system.
A Powerful Compact Controller
The ZEN Active Control System provides enough power to allow a precise wideband control
2 . For example, with a
sampling frequency of 15.6 kHz, the controller can optimize in real time:
992 coefficients for the non-coupled mode
290 coefficients for a coupled mode case (assuming 400 coefficients for primary and secondary control paths)
Cost Effective
Based on the powerful but cost effective SR-MK2
TM DSP board, the ZEN Active Control System is suitable for
research laboratory requirements, but it is also ideal for industrial and commercial applications. Specific version of the
ZEN Active Control System can also be provided as an OEM product.

The number of coefficients of the control filter determines the accuracy of an active wideband controller. More coefficients allows a better
definition of the control filter and precision to reduce the signal over the entire frequency band. The maximum number of coefficients for the
control filters depends on many factors: the optimization frequency, the number of channels and the number of coefficients for the control filters.
