    Subwoofer low-pass filter settings The Optimizer includes a subwoofer low-pass filter with the following options: Cutoff frequency (default is “disabled”): defines the cutoff frequency for the low-pass filter that can be applied to the subwoofer. • • Filter type (default is Butterworth): defines the type of filter used at the cutoff frequency. The elliptic filter is sharper than the Butterworth but shows ripples in the whole bandwidth.

    6.5 2D/3D LOUDSPEAKER POSITION REMAPPING About the remapping The Loudspeaker remapping is one of Trinnov’s patented technology, based on the ability to calculate the acoustic field that is produced by a set of loudspeakers. Its purpose is to reduce spatial distorsion caused by a wrong loudspeakers positioning or to increase spatial resolution by using more speakers.

    Remapping modes Off (default): Remapping is disabled. Matrix: Specifies that the i/o routing to be taken into account is in the Config Editor. To be used by advanced users.

The remapping uses adjacent speakers to virtually correct wrong speaker placement. In this example, the wrong center elevation will be compensated by 3D remapping, but The user-defined input format is 5.1 SMPTE but the real speaker layout is 7.1.

    11.6 MISCELLANEOUS Delay Lines Delay lines are provided in order to delay additional audio systems with the outputs of the Magnitude32 without being affected by the Optimization. Delay lines typically are used in broadcast environment to align audio monitoring between audio and video control rooms. Once created in the Speaker Settings page, delay lines can be set up in sources and speakers routing grids such as in the following example.
