Configuring the cardioid feature:
Once the user has configured the subwoofers on the greybox "setup" page, they will be able to align
these subs to create a cardioid effect.
1. Determine the distance from the face of one subwoofer to another. The legend on the feature is
your guide to determining this. The spacing must be equal regardless of how many subs deep the
arrangement is.
2. Set the cancellation angle. This tells the software how wide or narrow you wish the forward
coverage of the subwoofer array to be.
3. Measurement distance – if close to the array, the angle changes. This parameter is used to adjust
the cancellation angle accordingly.
4. LF EQ Compensation – EAW's technique for creating a cardioid does so at all frequencies but also
creates a 6 dB per octave roll off in the extreme low end below the center frequency. This selection
box applies a +4dB compensation EQ to make up for this loss.
5. Center Frequency – Sets the center frequency below which the LF Compensation EQ will be
applied.
6. Once the data has been entered, hit the "Setup Cardioid" button to create the pattern (note: even
though the delay times are not displayed in Pilot for the Cardioid, it has been implemented)
7. Hitting the "Clear Cardioid" button cancels the feature.
