DUAL-FILTER MODE

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.
