Zoom
A zoom control is used to expand the plot view to review details in the filter settings. As the
zoom control is increased, the plot will be centered to within the graphical plot area.
Filter Type
The filters can be cascaded to create a band pass filter or placed in parallel to create a notch
filter. There are two filters that are used to create a low pass, high pass, notch, band pass, and
off. For the high and low pass arrangement, a filter is removed (turned off) in the audio
processing stream.
Low/High Filter Parameters
Each filter has frequency and Q settings. For a band pass filter, the low pass filter will set the
upper frequency limit, and the high pass filter will control the lower limit.

CROSSOVERS TAB
The Crossover Tab is used to configure crossovers and other outputs where a single channel
drives multiple band outputs (see section 5.2 for block diagrams showing crossovers and other
outputs). In this view there is response curve plot that is used to provide feedback for the
crossover settings. The actual response can be viewed by selecting the RTA view.
Along the top of the Crossover Tab display are buttons that select which channel the current
display applies to. Note that all channels are listed, including those where no crossover controls
are available. If a channel without crossover controls is selected, the controls will be grayed out.
