DS-90: Whats Speaker Modeling?
Speaker Modeling is a feature which uses digital signal processing to model the
changes in sound quality produced by a particular speaker during audio output.
This lets you use one type of monitor speaker to emulate speakers from other
manufacturers, and even the speakers from small household-use television sets
and other equipment. You can use the DS-90 in combination with this to simulate
the sound checks at mixdown, which conventionally have required switching
between multiple pairs of monitors set up to compare the sound.
