The crossover frequency for the 2-band DRC by default is 300Hz. This can be modified by entering a new value in the property window.

The DRC rates for the softening filter, attack, and release can also be adjusted. To set these rates, first click on the UPPERBAND or LOWERBAND block. Second, set the RateSliders property to On for that block. Third, double-click on the block to bring up an advanced DRC options window, as shown in Figure 13.
