Filter Channel Name — This name changes to match the default or user defined input

name.

Filter Graph — Graphically displays the applied filter curve and provides handles for

adjusting filter parameters. Numbers along the top of the graph represent the filter curve

of the corresponding slot in the filter list below the graph. The number appears over the

center frequency of the filter.

If a filter is active (unbypassed), it appears as a solid red curve. If a filter is bypassed, it

appears as a broken orange curve (such as the bass filter in slot 2).

NOTE: All filters are bypassed by default.

Filter List — Provides filter drop-down menus for all 5 available filter slots. Frequency,

Slope, Boost/Cut, Q, and Bypass controls are also available in this list.

Available filters include:

• High Pass Butterworth • High Pass Linkwitz-Reily

• Low Pass Butterworth • Low Pass Linkwitz-Reily

• Bass • High Pass Bessel

• Treble • Low Pass Bessel

• Parametric • Loudness

• Notch

NOTE: See the DSP Configurator Help file for more information on each of the
