In the dual-filter mode one mono signal is accepted
(see Fig.5) The input can be selected from either one of
the 2 stereo inputs (from the left or right input channel).
DC filtering is performed at the input before further
processing. Two separate corrections, in parallel, can be
performed by means of an 8-band graphic equalizer.

16 poles and 16 zeros can be selected arbitrarily from the
Z-domain. At the output, one of the channels can be
delayed internally by the DAPIC. The two corrected
outputs can be added to either one of the two stereo
outputs.
The application for this mode is in loudspeaker correction.
