Kit Operation
If filter coefficients are known, they can be entered directly on this tab (Figure 11 ) for both biquads for both
left and right channels. The filter response will not be shown on the Effect Filter Response graph for user
filters.

The 3D effect is described in the TLV320DAC32 data sheet. It uses the two biquad sections differently
than most other effect filter settings. To use this effect properly, make sure the appropriate coefficients are
already loaded into the two biquad sections. The User Filters tab may be used to load the coefficients
(Figure 12 ).
Figure 12. 3D Effect Settings
To enable the 3D effect, check the 3D Effect On box. The Depth knob controls the value of the 3D
Attenuation Coefficient.
